Resistance gene cloning from a wild crop relative by sequence capture and association genetics

Disease resistance (R) genes from wild relatives could be used to engineer broad-spectrum resistance in domesticated crops. We combined association genetics with R gene enrichment sequencing (AgRenSeq) to exploit pan-genome variation in wild diploid wheat and rapidly clone four stem rust resistance genes. AgRenSeq enables R gene cloning in any crop that has a diverse germplasm panel. The treasure trove of disease resistance genes present in wild relatives of domesticated crops is rapidly discovered using association genetics and enrichment sequencing.
