Interpretive Summary: The soybean cyst nematode is the major pest of soybean and causes an estimated one billion dollars in damages annually in the U.S. Recent advances in genomic research include sequencing of the genomes of soybean and of the nematode. Massive gene expression data provide new insights into the interaction of the nematode with its host. These advances provide new opportunities for research to broaden resistance of soybean to the nematode. These data are of interest to scientists seeking to understand modes of resistance of plants to nematodes.

Technical Abstract: Glycine max (Merr), soybean, is a major agricultural crop under constant siege by a myriad of pathogenic organisms. The most costly of these pathogens is the soybean cyst nematode (SCN), Heterodera glycines. This review focuses in on the recent genomic research, including the sequenced genomes of both soybean and SCN. The review discusses how genomic information is being used to identify soybean and SCN genes involved in regulating the interaction with attention paid to recent reverse genetic technology used to functionally test those genes in genetic engineering experiments.
