SUMMARY:Oleksandra Shabliy
DESCRIPTION:Title: Strategies to Improve Resistance to Wheat Powdery Mildew\n \nAbout Oleksandra\nOleksandra is a Master’s student in the Department of Plant Pathology. Originally from Kyiv\, Ukraine\, she earned her B.S. in Biotechnology and Bioengineering from the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute.” Her undergraduate work focused on industrial biotechnology and the development of microbial production processes for pharmaceutical compounds. Oleksandra previously worked at the Institute of Microbiology and Virology of the National Academy of Sciences of Ukraine\, where she was involved in research related to microbial biodegradation and bioenergy production. Her current research focuses on wheat root endophytic Actinobacteria and how they may help wheat tolerate drought stress\, suppress soilborne pathogens\, and maintain plant health under stressful growing conditions. In her free time\, Oleksandra enjoys spending time with her friends\, hiking\, and doing jigsaw puzzles \nAbstract\nWheat powdery mildew\, caused by Blumeria graminis f. sp. tritici (Bgt)\, ranks among the most significant foliar diseases affecting wheat globally. Annual yield losses are estimated between 7.6% and 19.9% in affected regions (1). Research indicates that this pathogen originated in the Fertile Crescent and expanded with wheat cultivation\, enhanced by human migration and trade\, which influenced its global spread (2). \nPowdery mildew is hard to control because Bgt is an obligate biotrophic fungus and has adapted to resistance used in breeding programs. Many resistance genes (R genes) allow the plant to recognize the pathogen and activate defense responses\, but they often function only against specific pathogen strains. As a result\, this resistance can lose effectiveness as the pathogen population changes over time (2). Surveys in the U.S. showed that several older powdery mildew resistance (Pm) genes have already been broken down\, especially in eastern soft wheat production regions. Pm3a\, Pm4a\, and Pm17 are some of the main examples\, showing that resistance based on a single major gene is often not durable (3). \nBecause of this\, researchers are looking for ways to make powdery mildew resistance more effective and longer-lasting. One approach is gene stacking\, in which multiple resistance alleles are combined in a single wheat line. It was shown that stacking multiple transgenic Pm3 alleles gave better field resistance than lines carrying only one allele. This stronger resistance seemed to come from both higher total transgene expression and the combination of different allele specificities. Importantly\, the stacked lines did not show negative effects on plant development or yield. In some allele combinations\, no powdery mildew infection was observed under field conditions (4). \nA second approach focuses on susceptibility genes (S genes) instead of R genes. Editing the wheat MLO-B1 locus produced the mutant Tamlo-R32\, which had strong powdery mildew resistance without the growth and yield losses often seen in earlier mlo mutants. This line carried a 304-kb deletion in the MLO-B1 region and maintained normal plant height and grain yield while greatly reducing fungal colony formation (5). \nA third approach is to introduce resistance genes from wild relatives to broaden the wheat resistance gene pool. Durum wheat was used as a bridge to transfer Pm60 and Pm60b from diploid Triticum urartu into common wheat. Using crossing\, backcrossing\, and marker-assisted selection\, several recombinant introgression types were identified\, and resistant lines with high self-fertility were developed. Their results show that wild relatives are still an important source of new resistance genes for improving powdery mildew resistance in wheat (6). \nOverall\, wheat powdery mildew remains a major challenge because the pathogen continues to overcome widely used resistance genes. However\, strategies such as gene stacking\, susceptibility-gene editing\, and introgression from wild relatives offer promising ways to improve resistance and reduce future losses in wheat (2–6). \nPlant Pathology 515\, 3rd Semester\, 2nd Year \n\nSotiropoulos\, A.

SUMMARY:Kara Lanning (student invited speaker\, Pacific University\, Oregon)
DESCRIPTION:Plant Pathology in Context: Teaching\, Research\, and Community Engagement at a Small Liberal Arts Institution.\nAbout the Presenter\nDr. Kara Lanning is an Assistant Professor in the Department of Environmental Studies at Pacific University (Forest Grove\, Oregon\, USA)\, where she teaches courses in plant science\, and sustainability science. Her current research focuses on plant pathogens\, particularly Phytophthora species\, and their potential ecological impacts in the Pacific Northwest. Dr. Lanning mentors undergraduate students in field-based research\, fostering their engagement in high-impact learning experiences that integrate scientific inquiry with community-based environmental stewardship. \nDr. Lanning is dedicated to advancing undergraduate research opportunities\, helping students develop critical thinking skills while contributing to meaningful scientific work. Her research also emphasizes the importance of community engagement\, as she collaborates with local organizations to promote environmental conservation\, inform sustainable practices\, and provide place-based ecological information for strategic and informed decision making. Dr. Lanning’s work reflects her commitment to environmental stewardship\, particularly through efforts that bridge academic research with real-world applications in ecosystem management and pathogen prevention. \nAs an educator\, Dr. Lanning employs innovative teaching strategies to empower students\, cultivating both their academic growth and their role as informed citizens in addressing environmental challenges. \nAbstract\nThis seminar traces my professional experiences as a doctoral student at Washington State University (Ph.D Horticulture) to my current role as Assistant Professor of Environmental Studies at a small liberal arts institution. I will reflect on how my disciplinary background in Horticulture and Plant Pathology is highly integrated in my present work in sustainability-focused teaching and research programs\, and how the demands of working at a teaching-focused institution has reshaped my professional identity and definitions of scholarly impact. \nA central theme of the seminar is how teaching and curriculum development differ in undergraduate versus graduate-centered contexts. While graduate education often assumes disciplinary fluency and high levels of independence\, undergraduate-focused teaching requires intentional scaffolding of research skills\, explicit cultivation of scientific identity\, and structured opportunities for experiential learning. I will share examples of pedagogical strategies I use in ENV 410: Plant Pathology that maintain disciplinary rigor and provide a strong grounding in foundational concepts. I have found that these approaches have broadened access to the field\, allow for systems thinking integration\, and highly engage students in a field that is typically offered at R1 institutions. \nFinally\, I will discuss both the challenges and the rewards of conducting research in an undergraduate-focused laboratory\, and how disciplinary expertise in Plant Pathology can translate into community-engaged scholarship and transformative student research experiences. I will describe my approach to designing field-based surveys of local plant pathogen communities that center student development alongside knowledge generation. This model requires rethinking traditional metrics of productivity\, mentorship\, and impact. \nZoom Recording\n

SUMMARY:Jeremy Johnson
DESCRIPTION:Zoom Recording \nUncovering the Protective Characteristics of Fungal Endophytes in Mangrove Trees\nAbout The Presenter\nJeremy is currently a first-year master student in the USDA Grain Legume Genetics Physiology Research Unit in Pullman Washington. Jeremy completed his B.S. in Biochemistry at Washington State University. As an undergraduate Jeremy joined the research unit and has just reached his fifth year with the team as of April 2026. In his time with the unit\, he assisted with research relating to disease resistance in chickpeas to different fungal diseases including Ascochyta blight and pythium seed rot. For his masters Jeremy is working to identify SNPs associated with disease resistance to Ascochyta blight utilizing the mini dome disease screening assay through GWAS. He is also working to identify Ascochyta blight resistant materials in new F2  populations recently generated through the chickpea breeding program. In his free time Jeremy enjoys spending time with his friends and family\, walking his dog Noelle\, hiking\, and volunteering with the Scouting America. \nAbstract\nEndophytes have diverse roles in supporting the survival of a host plant both directly and indirectly through nutrient acquisition\, defense against pathogens\, mediating adverse environmental conditions (4\,5\,6). Mangrove trees are species of woody plants that live in coastal and estuary zones of tropical and subtropical climates (5). Their ability to survive under harsh environmental conditions has sparked interest in their endophytic fungi (1\,4) Two current research topics pertaining to mangrove endophytes focus on their role in bioremediation and advancing pharmacology (1\,4\,5\,6). \nEndophytes from polluted and undisturbed mangrove populations were examined to determine how water quality influenced endophyte diversity and their ability to solubilize phosphate and zinc (3). The polluted site had a more diverse community of fungal endophytes\, which rejected the initial hypothesis that diversity would be greater in the community collected from undisturbed population. Only isolates from the polluted site demonstrated exceptionally high levels of phosphate solubility while isolates from both sites proficiently solubilized zinc. This study provided knowledge about the diversity of endophytes within mangrove ecosystems and identified endophyte species that may contribute to developing mangroves to manage agricultural and industrial pollution in coastal regions (4\,5\,6). \nThe endophyte Purpureocillium lilacinum A5 was investigated for its role in alleviating copper stress in the mangrove tree Kandelia candel (2). Purpureocillium sp. A5 altered the content of chlorophyll A and B\, the Relative Water Content (RWC) and Water Saturation Deficit (WSD) in colonized leaves\, which promoted plant growth compared to the uncolonized control. Plants colonized with Purpureocillium sp. A5 absorbed less copper than control plants. Significant differences were observed between soil from colonized and control plants in pH\, quantity of toxic Cu+ ions\, and the formation of carbonate-bound Cu\, Mn–Fe complexes Cu\, and organic-bound Cu. These results suggested mechanisms by which fungal endophytes can assist mangrove trees subjected to adverse soil conditions. \nEndophytes from two different mangrove species\, Rhizophora stylosa and Rhizophora mucronate\, were screened for antimicrobial activity against human pathogenic bacteria and cytotoxic effects against cancer cells lines (7). Two isolates from R. mucronate showed significant effects at inhibiting microbial growth at concentrations between 0.015-1 mg/mL. Cytotoxicity screening identified five isolates between both mangrove species that displayed significant antitumor activity\, with inhibitory concentrations (IC50) values below 20 μg/mL. These results show promise for the future development of new pharmaceuticals derived from mangrove endophytes (1\,4\,6). \n

SUMMARY:Chakradhar Mattupalli (guest speaker from WSU)
DESCRIPTION:Berry and potato pathology program: A marriage of convenience\nBio: Chakradhar Mattupalli is an Assistant Professor in the Department of Plant Pathology at Washington State University. He earned his B.S. and M.S. in Agriculture from India\, and Ph.D. in Plant Pathology from the University of Wisconsin-Madison. He worked as a postdoctoral researcher at the Noble Research Institute LLC\, in Ardmore\, OK\, and then joined Colorado State University\, where he was a Research Professor and Extension Specialist at the San Luis Vally Research Center. Since February 2021\, he has been leading the Berry and Potato Pathology program at WSU Mount Vernon Northwestern Washington Research and Extension Center. Mattupalli’s research focuses on understanding pathogen biology and developing disease management strategies for blueberry and potato crops in northwest Washington. \nAbstract: The Berry and Potato Pathology program pivots on two commodity crops: highbush blueberry and potato. Washington state produces 26% of blueberries grown in the U.S.\, generating an annual revenue of $205 million. Fresh market potatoes are widely grown in Skagit County\, produced on about 11\,000 acres with a farm gate value of $70 million. In addition\, northwestern Washington has a designated seed potato isolation district to ensure the production of superior quality seed potatoes. The mild maritime climate in this region\, coupled with new production and pest management issues\, poses unique challenges to blueberry and potato growers. In this seminar\, I will summarize five years of grower-oriented research and Extension activities focused on developing disease risk models\, promoting fungicide stewardship\, understanding biology of soilborne pathogens\, and improving methods for molecular detection of pathogens. \nZoom Recording\n

SUMMARY:Kylie Swisher Grimm (guest speaker from USDA)
DESCRIPTION:Improving our understanding of Tobacco rattle virus\nAbstract\nTobacco rattle virus causes internal and external tuber necrosis that render potatoes unmarketable. The virus is vectored to potato in the northwest U.S. by the stubby root nematode\, Paratrichodorus allius\, and commercial growers control the virus through costly chemical controls that target the nematode.  Basic research strategies have been conducted in the greenhouse to improve our understanding of virus movement within a plant and factors that influence nematode fecundity. Applied research strategies have been utilized in the field to identify strategies that growers might use to mitigate the effects of the virus on tuber yield and quality. As part of the Tri-State Potato Variety Development Program\, breeding clones are screened each year for resistance to Tobacco rattle virus-induced internal tuber necrosis. Information gained from each of these projects can combine to improve strategies that commercial growers currently use to mitigate Tobacco rattle virus and its nematode vector. \nAbout Kylie\nKylie Swisher Grimm is a Research Plant Pathologist at the USDA-ARS Temperate Tree Fruit and Vegetable Research Unit located in Prosser\, WA. Her research focuses on the epidemiology\, biology\, and management of new and emerging pathogens of potato and vegetable crops in the Northwestern U.S. One aspect of Dr. Grimm’s research focuses on insect-vectored pathogens such as ‘Candidatus Liberibacter solanacearum’ and ‘Candidatus Phytoplasma trifolii’ that are the causal agents of zebra chip and potato purple top diseases\, respectively. She has worked to identify novel pathogen haplotypes\, identify host plant and insect vector associations\, and develop new molecular tools for high-throughput insect testing. Another aspect of Dr. Grimm’s program focuses on soilborne pathogens that cause internal tuber necrosis such as Tobacco rattle virus and Potato mop-top virus that are vectored by stubby root nematodes and Spongospora subterranea\, respectively. Much of this work has been on understanding the relationship between pathogen\, host\, and vector\, as well as identifying disease-resistant germplasm that will benefit growers in the region. Dr. Grimm’s background in molecular biology pairs nicely with the field and greenhouse trials routinely conducted in her program. \nZoom Meeting Information\nZoom Link\nZoom Meeting ID: 959 0545 7360\nZoom Password: 2488

SUMMARY:Elaine Larsen
DESCRIPTION:Elaine Larsen\nZoom Recording \nFungi as Vectors of Plant-Pathogenic Viruses\nViruses are the most abundant biological entity on Earth\, infecting all cellular organisms across terrestrial and marine ecosystems [1]. Plants are known to be infected by diverse viruses and viroids (i.e.\, virus-like\, unencapsidated\, single-stranded RNA particles) belonging to at least 35 families [2]. Several viral families contain structurally related viruses that infect either plants or fungi (i.e.\, mycoviruses)\, and several viral genera infect both plants and fungi [2]. The majority of research on plant viruses has focused on pathogenic viruses that cause disease in agricultural crops and account for the annual global loss of ca. $30 billion [3]. Plant pathogenic viruses are typically vectored by sap-sucking arthropods [4]\, but the potential for fungi to act as vectors for plant-pathogenic viruses was discovered as early as the 1970s\, when tobacco mosaic virus (TMV) was identified in the asexual spores (conidia) of a powdery mildew fungus [2]. Since then\, several plant viruses have been successfully inoculated into fungi and oomycetes\, with some resulting in stable infections [5-8]. Similarly\, studies have shown that viroids can infect yeasts ( Saccharomyces cerevisiae )\, plant-pathogenic filamentous fungi\, and the oomycete pathogen Phytophthora infestans [9-11]. Viroids also have been transmitted successfully between fungal hyphae via hyphal fusion and persist in spores after asexual reproduction [11]. Although plant viruses could exist within fungal cells\, they were not known to undergo replication [2]. However\, it is now recognized that some plant viruses and viroids can replicate within fungal cells\, suggesting that fungi may both vector and amplify viral loads [5-11]. Beyond simply being vectored by fungi\, viruses and viroids can modulate the pathogenicity of infected fungi [2]. In some cases\, the severity of plant disease caused by plant-pathogenic fungi has been shown to either increase or decrease when fungi are infected by plant viruses [7]. While most viroid infections appear to be asymptomatic in fungi\, hop stunt viroid (HSVd) reduced growth and pathogenicity in the plant-pathogenic fungus Valsa mali [11]. Mycoviruses may also reduce the pathogenicity of pathogenic fungi and have been researched as potential biological control agents [2\,12]. Virus-induced hypovirulence has been observed in Cryphonectria parasitica \, the causative agent of chestnut blight\, and Ophiostoma ulmi \, which causes Dutch elm disease [2\,12]. Demonstrating the potential for both pathogenic and non-pathogenic fungi to serve as vectors of pathogenic viruses\, a recent study found that fungal endophytes isolated from the leaves of plants exhibiting symptoms of viral infection carried a number of plant-pathogenic viruses [8]. Overall\, the long evolutionary history of close endosymbiotic relationships between plants and fungi—ranging from parasitic to mutualistic interactions—appears to have shaped the evolution\, host specificity\, and transmission of plant viruses [2]. However\, more research is needed to understand the role of pathogenic and non-pathogenic fungi in vectoring plant-pathogenic viruses and the implications of fungus-virus interactions on plant disease management.

SUMMARY:Francely Flores
DESCRIPTION:Title: Modes of seed transmission of plant pathogens and their epidemiological importance\nZoom Recording \nBio\nFrancely is currently a Ph.D. student in the Berry and Potato Pathology Program at the Mount Vernon Northwestern Washington Research and Extension Center. She earned her B.S. in Agricultural Engineering from EARTH University\, Costa Rica in 2020\, and her M.S. in Sustainable Tropical Agriculture from Zamorano University in Honduras in 2023. Her master’s research focused on the adaptability and yield performance of introduced tomato lines under greenhouse and open-field conditions in Honduras. She has completed international internships in the Dominican Republic and at the World Vegetable Center in Taiwan. Her current research focuses on the management of Verticillium dahliae\, a soilborne pathogen affecting potato and several crops in western Washington. In her free time\, she enjoys reading\, listening to music\, playing badminton\, and drinking coffee. \nAbstract\nSeeds are foundation for successful crop production. However\, seeds can also serve as an important source of primary inoculum for diseases and facilitate long-distance movement of plant pathogens [1\,2]. Plant pathogens may be associated with seeds externally through contamination occurring in the field or during storage\, or internally through infection of the embryo or  non-embryonic tissues such as the endosperm or perisperm\, where transmission to the emerging seedling is not necessarily assured [1\,3]. These different modes of pathogen transmission by seeds influence epidemiological risk and disease outcomes. \nAcross pathogen groups\, transmission mechanisms vary but can lead to similar epidemiological consequences. Bacterial pathogens such as Xanthomonas citri pv. fuscans and Xanthomonas phaseoli pv. phaseoli\, the causal agents of common bacterial blight of bean\, may occur on the seed surface or within internal seed tissues and initiate epidemics at infection frequencies as low as one infected seed per 10\,000 to 30\,000 seeds. Hence\, seed health and phytosanitary programs have set a zero tolerance level for this pathogen on bean seeds  [4\,5]. Fungal pathogens\, such as Fusarium circinatum\, which cause pitch canker disease of pine\, are often externally seed-borne. However\, they can still cause severe disease in forest systems due to high seedling mortality and latent infections\, allowing the pathogen to persist undetected during early vegetative growth\, particularly in nursery production of pine seedlings – a risk that has led to the implementation of quarantine and strict phytosanitary measures [6\,7]. In contrast\, seed transmission of plant viruses is biologically limited and typically requires infection happening during a narrow window of embryonic development [1\,8]. This form of transmission represents vertical transmission\, in which the pathogen moves from the parent plant into the seed embryo. Viruses such as pea seed-borne mosaic virus can infect embryo of the seed posing epidemiological risk\, with risk levels varying among host cultivars [9]. In addition\, certain nematodes\, including Ditylenchus dipsaci\, are true seed-transmitted plant pathogens that survive in seeds in a dormant state and introduced to new areas due to long distance movement of seed\, often prompting strict quarantine measures [10–12]. \nA low frequency of seed infection does not equate to low epidemiological importance. Global seed trade amplifies these risks by enabling repeated and long-distance movement of pathogens beyond the limits of natural dispersal\, while detection challenges at low infection levels complicate effective risk management [13\,14]. Although advances in diagnostics and seed health systems have improved phytosanitary protection\, important challenges remain\, including identification of detection limits of pathogens relative to epidemiological risk\, influence of environmental conditions on transmission dynamics\, and the need for improved risk-based decision frameworks that  link seed health test results to epidemiological and economic thresholds for phytosanitary decision-making [13\,14]. The objective of this seminar is to examine how seed transmission pathways influence epidemiological risk and disease management across different plant pathogen groups. \n Literature Cited\n\nBaker\, K.F.\, and Smith\, S.H. 1966.

SUMMARY:Eric Holmes (guest speaker from University of Idaho)
DESCRIPTION:Study\, evolution\, and engineering of plant-microbe interactions to address emerging agricultural challenges.\nAbiotic and biotic stressors pose a significant threat to agriculture and global food security. As a rising demand for food and negative impacts from these stressors co-occur\, transformational changes to our agricultural systems will be necessary to efficiently feed the planet. New technologies that leverage the plant microbiome to improve depleted soils\, reduce crop loss\, and augment energy-intensive fertilizers promise to contribute toward this transformation\, yet additional mechanistic insight into plant-microbe interactions is necessary to fully exploit this potential. In the Holmes Lab\, we seek to define these molecular mechanisms and apply our insights to engineer microbial bioproducts that improve plant health and fitness. In this seminar\, I will present two case studies that exemplify this approach. First\, I will describe our work discovering and characterizing N-hydroxypipecolic acid\, a previously unknown plant hormone that is essential for systemic immune defense. Second\, I will discuss my prior industry work where we translated new biochemical insights into the development of a more effective bacterial anticancer vaccine. Together\, these examples highlight how mechanistic understanding of cross-kingdom biological systems can be harnessed to design impactful engineered bioproducts. \nEric’s Bio\nDuring his graduate work in Elizabeth Sattely’s lab at Stanford University\, Eric developed metabolic and genetic screening approaches to discover and engineer metabolite-based pathogen defense mechanisms in plants. Post-PhD\, Eric spent several years in industry\, working with microbiome therapeutic startups to develop novel genetic engineering strategies for bacterial-based therapeutics. He then transitioned to a Postdoctoral Researcher position at the National Renewable Energy Laboratory\, where he worked in Gregg Beckham’s group to develop strategies for producing sustainable food products from waste resources. In 2025\, Eric started his lab at the University of Idaho\, where he leverages expertise in plant chemistry\, metabolomics\, microbiology\, and synthetic biology to uncover and engineer the mechanisms that underlie critical interactions between plants and microbes. Eric was born and raised in Oregon and spends his spare time enjoying the Pacific Northwest’s many recreational opportunities. In particular\, he enjoys backpacking\, fly fishing\, wildlife photography\, running\, and vegetable gardening. \n

SUMMARY:Prabu Gnanasekaran (Guest Speaker from WSU)
DESCRIPTION:Insights from Diverse Plant Virus Systems: Mechanisms and Management\n \nZoom Recording\nAbout the Presenter\nPrabu Gnanasekaran is a Research Associate working with Prof. Hanu Pappu in the Department of Plant Pathology at Washington State University. He earned his Ph.D. in Life Sciences with a specialization in Molecular Plant Virology from Jawaharlal Nehru University\, India\, and subsequently pursued postdoctoral research at Washington State University. Dr. Prabu’s research focuses on the molecular and biochemical mechanisms underlying plant–virus interactions\, with particular emphasis on economically important plant viruses affecting horticultural and agricultural crops. His work spans studying viral protein function\, host defense responses\, resistance-breaking mechanisms\, and virus-induced alterations of host metabolism. He has extensive experience with molecular\, proteomic\, and cell biology approaches to study viral pathogenesis. In addition to fundamental research\, Dr. \nPrabu is leading the Dahlia Resource Center activities at WSU\, including the developing diagnostic tools\, managing diagnostics\, establishing virus elimination tissue culture pipeline and maintaining clean stock of popular dahlia cultivars. \nAbstract\nViruses use diverse strategies that include disrupting host physiology and development\, and defense pathways to cause disease. My research focus has been on gaining insights into host-virus interactions of diverse DNA and RNA viruses that include caulimoviruses\, geminiviruses\, potato virus Y (PVY)\, tomato spotted wilt virus\, and viroids. By combining molecular\, biochemical\, and genomic approaches\, my research has provided insights into how different plant viruses manipulate host cellular processes to promote infection and disease development. Also\, using the knowledge gained from the molecular studies\, I developed molecular diagnostic tools for reducing the impact of these viruses. \nGeminiviruses cause some of the most economically damaging diseases in food\, feed\, and fiber crops in tropical as well as subtropical regions of the world. Geminivirus–betasatellite complex is an important model for understanding DNA virus pathogenicity and host – virus interactions. I showed that the betasatellite-encoded pathogenicity determinant βC1 targets chloroplast function resulting in vein clearing\, and impaired photosynthesis. βC1 interacts with chloroplast-associated host factors and viral replication proteins to modulate host defense responses and helper virus replication leading to the establishment of virus infection. \nIn case of economically important RNA viruses\, PVY is a constraint to potato production here in WA and other potato producing regions of the world. I showed that PVY exploits host hormone and metabolic pathways: PVY-coded NIa-pro protein was shown to stabilize indole-3-acetic acid–amido synthetase to alter auxin homeostasis and enhance disease development\, while the PVY coat protein interacts with cytosolic phosphoglucomutase to reprogram host primary metabolism. \nDahlia is a high value flower\, and viruses are recognized as a major constraint by dahlia stakeholders. A nationwide survey and testing of more than 4k samples provided a better understanding of the nature and identify of viruses that affect dahlias. Two caulimoviruses\, dahlia mosaic virus and dahlia common mosaic virus were found to be widespread in dahlias. By comparative genomic analyses\, I resolved the taxonomic ambiguity by demonstrating that these two are variants of a single species\, with direct implications for diagnostics and disease management. A meristem tissue culture-based pipeline was established to produce virus-free dahlias with a goal to supply virus-free materials to stakeholders. \nTo address emerging phytosanitary challenges\, a rapid\, sensitive\, and field-deployable CRISPR/Cas13-based SHERLOCK assay was developed for detecting quarantine-significant pospiviroids in tomato and pepper. Together\, these studies integrate mechanistic understanding of virus-host interactions with practical diagnostic and management tools\, highlighting how insights from diverse plant virus systems can advance sustainable disease
