February in the News

Faculty Organize the Pacific Northwest Barberry Working Group Meeting The first meeting of the Pacific Northwest Barberry Working Group took place in Spokane, WA February 9-10, 2011. The meeting was hosted by the Washington Grain Alliance and Tim Murray, Xianming Chen, and Diana Roberts from the Washington State University Department of Plant Pathology, USDA-ARS, and WSU-Extension, respectively. The working group is comprised of representatives from Washington, Idaho, Oregon, and western Montana, and USDA-APHIS and USDA-ARS. The working group was established to address common barberry in relation to outbreaks of stem rust of wheat and barley in the region and the development of potentially damaging new races of the stem rust fungus.  Common barberry was not eradicated or has reestablished since the Federal Barberry Eradication Program ended in 1981 and is the primary source of stem rust infections in the region. Activities of the Working Group include educating the wheat and barley industry to recognize stem rust and barberry and report it to appropriate local research and extension personnel so pathogen races can be monitored. The group is also developing recommendations for eradication of barberry using currently available herbicides.

Australian Researcher Visits Department
                 
Dr. Daniel Hüberli, Research Officer / Adjunct Senior Lecturer, Murdoch University and Department of Agriculture and Food, Perth, Australia visited the department on  February 17-18. The visit was facilitated by Dr. Tim Paulitz, ARS Research Plant Pathologist and Adjunct Professor. Dr. Huberli gave a seminar, “Fishing for Phytophthoraacross Western Australia’s waterways and in-furrow control of root and foliar pathogens in wheat”.  He met with faculty, postdocs and graduate students during his visit.(Photo from left: Drs. Marianne Elliott, Daniel Huberli, Tim Paulitz and Mr. Ebrahiem Babiker)

Student Receives Travel Award

Jeremiah Dung, PhD student with Dr. Dennis Johnson, was selected to receive a travel award to attend the Conference on Soilborne Plant Pathogens, March 21-23 at UC Davis.

He will be presenting a talk titled “Genotypic diversity of Verticillium dahliae impacting potato and mint”.


Emeritus Faculty Receives Wolf PrizeDr. Jim Cook, Professor Emeritus of Plant Pathology , has been chosen to receive the 2011 Wolf Prize in Agriculture. The award will be presented to Dr. Cook by the President of the State of Israel, and the Israeli Minister of Education, at a special ceremony at the Knesset in Jerusalem, on Sunday, May 29, 2011.

A feature on this Dr. Cook’s award was published in the February 16 edition of WSU Today, Seattle Times on February 15, and CAHNRS News on February 15.

Congratulations on this prestigious award!

Wheat Health Expert from Australia Visits the DepartmentProf. Robert Park of the University of Sydney, Australia visited the department on February 11.  He gave a seminar, ‘Experiences and challenges in cereal rust control in Australia’. Dr. Park visited with several plant pathology and crops and soils faculty during his visit. Dr. Park’s visit was facilitated by Dr. Xianming ChenDr. Robert Park is the chair of Rust Research of the Grains Research and Development Corporation (GRDC) and the director of the Australian Cereal Rust Control Program (ACRCP) at the Plant Breeding Institute, the University of Sydney.

The major research interests of his research group include genetics of resistance (including classical, molecular and cytogenetics), pathogenic and molecular variability in rust pathogens, and more recently, functional genomics of host-pathogen interactions, particularly interested in the way in which fungal rust pathogens evolve and acquire virulence for resistance genes in their hosts. He has expertise in all cereal rust with special interest in wheat, leaf and stem rust, leaf rust in barley and crown rot in oats. Dr. Park has conducted Australia-wide race analyses for the rust pathogens that cause stem rust in wheat, leaf rust in wheat, leaf rust in barley, and crown rust in oats, for the past 20 years. His research group is now developing and applying DNA-based markers to test hypotheses on how rust pathogen populations have evolved in Australia over the past 90 years. He is also interested in the genetics of resistance to rust pathogens in their respective hosts, and his group works very closely with most cereal breeders in Australia for rust resistance breeding. Dr. Park is also actively involved in international rust research, notably via his participation in the global effort to tackle a new race of stem rust, known as Ug99, that has emerged in eastern Africa in recent years.
