Overview of current program:
Soybean sudden death syndrome (SDS) is caused by the fungus Fusarium virguliforme, and has potential to significantly reduce yields. The 2010 growing season saw unprecedented levels of SDS across Michigan and north central states. Observations indicate that SDS appears to be established in the lower half of Michigan and is moving north. SDS is a difficult disease to detect and monitor as it is soil borne and does not always produce distinctive foliar symptoms. In addition, foliar SDS symptoms can often be confused with other soybean diseases. We are mapping the distribution of F. virguliforme in Michigan to county level and examining it’s interaction with the soybean cyst nematode (SCN) using a combination of molecular and culturing techniques. We are also developing and refining greenhouse screening techniques for SDS resistance in collaboration with MSU’s soybean breeder Dr. Dechun Wang.
Sclerotinia white mold, caused by Sclerotinia sclerotiorum, is a devastating disease of many crop plants and can cause significant economic losses in pea under the appropriate environmental conditions. We are interested in dissecting the pea-Sclerotinia sclerotiorum interaction by examining the host and pathogen mRNA expression profile with next generation sequencing technology. Despite being Mendel’s model system, few genomic resources exist for pea. The expression profiling studies will provide valuable information on the genetics of the interaction between host and pathogen. Identification of genes and pathways involved in partial resistance will lead to a better understanding of the interaction and development of markers for breeding resistance to S. sclerotiorum. We envisage that these studies will lead to further insights and solutions for development of resistant material not only in pea but in other crops affected by Sclerotinia spp.
We have a strong interest in the development and more importantly application of molecular detection assays including high-through put systems and have worked on the development and application of several real-time PCR and standard PCR multiplex assays. My program is particularly interested in utilizing genomic resources and nuclide acid detection technologies to improve our understanding of fungal biology, disease etiology and epidemiology.
Extension and outreach activities:
Extension activities include participation in field days, annual meetings, publication of Field Crop Advisory Team (http://ipmnews.msu.edu/fieldcrop/) alerts throughout the season as disease issues develop. As well as participation in the Legume ipmPIPE (http://legume.ipmpipe.org/cgi-bin/sbr/public.cgi) and Asian soybean rust ipmPIPE (http://sbr.ipmpipe.org/cgi-bin/sbr/public.cgi) programs by providing disease observation data for Michigan and assisting with national commentary.
