MS Final Exam Success

Leslie Holland recently completed the requirement for a M.S. degree in Plant Pathology at Washington State University (WSU).  Her thesis was titled “Characterization of fungal pathogens associated with grapevine trunk diseases (GTD) in Washington State”.  Her thesis committee consisted of Dean Glawe (Chair), Gary Grove, George Vandemark, and Thomas Henick-Kling (director of WSU Viticulture & Enology Program).  Leslie’s study determined that incidence of GTD symptoms was positively correlated with vineyard age.  She isolated seven fungal species previously reported to be associated with GTD, including Cryptosphaeria pullmanensis, Diaporthe eres, Diatrype whitmanensis, Diplodia mutila, Diplodia seriata, Eutypa lata, and Eutypa laevata. She also identified species commonly isolated, but not established to cause GTD, including Cytospora rhodophila, Cytospora chrysosperma, Discostroma fuscellum, and Coniolariella limoniispora.  Her study provides a basis for future work to address important issues such as the biology of these fungi, diagnosis of grapevine dHolland final examiseases, and the epidemiology and management of this diverse group of pathogens.  Leslie grew up in Yellow Springs, Ohio.  She received her B.S. in Biology from New Mexico State University. During her M.S. program at WSU, she received scholarships from the American Society for Enology and Viticulture and the WSU Viticulture & Enology Scholarship.  She served as the President of the Plant Pathology Graduate Student Organization.  She will start this fall her Ph.D. program in Plant Pathology at the University of California, Davis under the advisement of Florent Trouillas.
