Research on clubroot in Brassicaceae suffers from a proliferation of names assigned to resistance (R) genes that are, in fact, identical. To date, only three genes have been truly validated: CRa, Crr1a, and RPB1. The authors call for a standardized nomenclature system and a centralized database to clarify the genetic landscape and better identify the actual mechanisms underlying resistance.
