Soybean Cyst Nematode Resistance Quantitative Trait Locus Alters the Expression of a γ-SNAP Protein.

Soybean cyst nematode (SCN) is the most economically damaging pathogen of soybean and host resistance is a core management strategy. The SCN resistance quantitative trait locus , introgressed from the wild relative , provides intermediate resistance against nematode populations, including those with increased virulence on the heavily used resistance locus. was previously fine-mapped to a genome interval on chromosome 15.

Soybean Resistance Locus Confers Resistance to Multiple Cyst Nematodes in Diverse Plant Species.

Cyst nematodes consistently threaten agricultural production, causing billions of dollars in losses globally. The (resistance to 1) locus of soybean () is the most popular resistance source used against soybean cyst nematodes (). is a complex locus that has multiple repeats of an ≈30-kilobase segment carrying three genes that contribute to resistance.
