The soybean aphid, Aphis glycines Matsumura, was introduced into the U.S. in 2000 and represents a growing risk to soybean production throughout the soybean growing region. A possible management tool is plant resistance. The soybean KS4202 has been identified as resistant (tolerant) to soybean aphids, but limited information is available on the mechanisms of the resistance and the genes conferring this resistance. Therefore, the objective of this study was to document genes differentially expressed between the resistant KS4202 soybean and the susceptible K03-4686 soybean in response to soybean aphid feeding through transcriptional profiling. Illumina sequencing was performed on leaf tissue harvested from resistant and susceptible soybeans at 5 and 15 days after aphid introduction. Results pending final analysis of the data.
