Soybean cyst nematode (SCN; Heterodera glycines) is a microscopic roundworm that feeds on
the roots of soybean causing more than $1 billion in losses to U.S. soybean producers annually. SCN
management relies heavily on the deployment of resistant soybean cultivars. The roots of plants carrying
Rhg (for resistance to Heterodera glycines) genes are penetrated by infective juveniles, but feeding cells
induced by the nematodes to serve as their sole nutritive source, degenerate prematurely. The recently
discovered identities of several Rhg genes in soybean to this nematode reveal that a new mechanism of
plant resistance to nematodes may be at play. A multi-pronged approach targeted at both the host and
pathogen using a combination of omics tools and technologies is underway. We hope these findings will help
us develop a mechanistic understanding of plant resistance and nematode virulence, as well as identify ways
to enhance the effectiveness and durability of natural plant resistance and the design of novel resistance
