Discovery of genes conferring host resistance to sweet potato weevils

Sweet potato weevils (SPWs) pose one of the greatest challenges to sweet potato production worldwide; however, the genetic basis of SPW resistance remains unclear. This study identifies two major SPW resistance genes in sweet potato and provides new insights into the mechanisms by which sweet potato defends against SPWs.
