Plant-parasitic nematodes are one of the most economically impactful pests in agriculture resulting billions dollars realized annual losses worldwide. Soybean cyst nematode (SCN) is number biotic constraint on soybean production making it a priority for discovery, validation and functional characterization native plant resistance genes genetic modes action that can be deployed to improve yield across globe.

An epistatic interaction between SCN resistance loci rhg1-a and rhg2 in PI 90763 imparts against virulent populations which can be employed to diversify soybean cultivars. With more than 95% of the $46.1B market dominated by a single type genetic resistance, breeding for cyst nematode (SCN)-resistant that effectively combat widespread increase presents significant challenge. Rhg genes (for Resistance Heterodera glycines) play key role SCN; however, their deployment beyond use rhg1-b allele...

Plant pathogens are constantly under selection pressure for host resistance adaptation. Soybean cyst nematode (SCN, Heterodera glycines) is a major pest of soybean primarily managed through resistant cultivars; however, SCN populations have evolved virulence in response to pressures driven by repeated monoculture the same genetic resistance. Resistance mediated multiple epistatic interactions between Rhg (for H. genes. However, identity genes that confer ability overcome remains unknown. To...
