Identification of Rcr12, a single dominant clubroot resistance gene near Rcr6 on chromosome B3 of Brassica nigra.

ABSTRACT:

Background

Clubroot disease, caused by the soil-borne protist Plasmodiophora brassicae, is a major threat to Brassica crops worldwide, leading to significant yield losses. Genetic resistance is the most effective and sustainable management strategy; however, the identification and characterization of clubroot resistance (CR) genes remain a challenge, particularly in Brassica nigra. Despite its abundant CR resources, only one CR gene, Rcr6, has been identified in the B genome of B. nigra, leaving much of its genetic potential unexplored. Understanding the genomic distribution and diversity of CR genes in B. nigra is crucial for expanding resistance breeding options, especially for canola (B. napus).
