Soybean cyst nematode (SCN, Heterodera glycines) is most effectively managed through planting resistant soybean cultivars, but the repeated use of same resistance sources has led to a widespread emergence virulent SCN populations that can overcome resistance. Resistance HG type 0 (Race 3) in cultivar Forrest mediated by an epistatic interaction between genes rhg1-a and Rhg4. We previously developed two inbred mass-selecting on susceptible recombinant lines, derived from cross SCN-susceptible...
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...
Abstract Heterodera glycines , the soybean cyst nematode (SCN), is a plant-parasitic capable of manipulating host plant biochemistry and development. Many studies have suggested that has acquired genes from bacteria via horizontal gene transfer events (HGTs) potential to enhance parasitism. A recent allelic imbalance analysis identified two candidate virulence genes, which also appear entered SCN genome through HGTs. One H. biotin synthase ( HgBioB ), contained sequence polymorphisms between...
