A Ca²⁺ sensor BraCBL1.2 involves in BraCRa-mediated clubroot resistance in Chinese cabbage.

ABSTRACT: Clubroot disease caused by Plasmodiophora brassicae (P. brassicae) severely threatens the cultivation of Cruciferous plants, especially Chinese cabbage. Recently, resistance genes in plants have been reported to encode for a Ca²⁺-permeable channel in the plasma membrane, which can mediate the cytosolic Ca²⁺ increase in plant cells upon pathogen attack. However, the downstream Ca²⁺ sensor and decoder are still unknown. In this study, we identified the virulent and avirulent P. brassicae isolates (Pbs) of two near isogenic lines, CR 3-2 and CS 3-2, with CR 3-2 harboring clubroot resistant gene BraCRa. The transcriptomic analysis was then conducted with CR 3-2 after inoculating with virulent isolate PbE and avirulent isolate Pb4. Fr
