February 2008


Soybean sudden death syndrome (SDS), caused by Fusarium virguliforme, is a root disease that results in severe foliar symptoms during the reproductive stage. In a regular growing season, an epidemic of SDS is highly correlated with the planting date and the disease tends to be more severe in earlier planted soybeans. This study’s objective was to understand the process of infection and colonization by F. virguliforme in vascular tissue leading to discoloration and subsequent foliar symptom expression in basal stems and taproots.
