"Genomics/Transcriptomics of Weed Stress Responses in Corn and Soybean," will be presented by David Horvath from North Dakota State University and USDA-ARS at 4 p.m., Oct. 23 in Beadle Center E103 (1901 Vine Street). The seminar is free and open to the public.
Weeds reduce crop growth and yield. It has been hypothesized that this is due to competition between crops and weeds that reduced resources (light, water and nutrients) available to the crop. However, observations that weed presence early in the growing season or late in the growing season had little impact on yield, as well as recent experiments that indicate weeds can reduce yields even if physically separated from the crop, suggest this hypothesis is invalid.
We have taken a transcriptomics approach to investigate and characterize signaling processes through which crop plants perceive weed presence and alter developmental programs leading to reduced yield.
