UK: The molecular mechanisms of Ca²⁺ sensor BraCBL1.2 in clubroot resistance in Chinese cabbage

Published 2024년 1월 16일

Tridge summary

Chinese cabbage is a widely cultivated leafy vegetable, but it is heavily affected by clubroot disease caused by Plasmodiophora brassicae. One of the earliest cloned clubroot resistance genes, BraCRa, has been identified as conferring resistance to this disease. A specific Ca2+ sensor, BraCBL1.2, has been found to be involved in the BraCRa-mediated clubroot resistance, providing a basis for further research on resistance to Plasmodiophora brassicae in Chinese cabbage.

Chinese cabbage (Brassica rapa L. ssp pekinensis) is one of the most important leafy vegetables cultivated worldwide. Clubroot disease caused by a soil-borne obligate biotrophic Plasmodiophora brassicae (Pb) severely affects the yield and quality of cruciferous crops, especially Chinese Cabbage. BraCRa, as one of the earliest cloned clubroot resistance genes, confers race-specific resistance to Pb.As TNL-type resistance (R) gene in plant, BraCRa is supposed to induce Ca2+ influx with the help of Ca2+ permeable channel. However, the identity of downstream Ca2+ sensors and decoders of BraCRa are still elusive.A manuscript entitled "A Ca2+ sensor BraCBL1.2 involves in BraCRa-mediated clubroot resistance in Chinese cabbage" published as article in Horticulture Research.The aim of this study is to identify the specific isolates of Pb protested by BraCRa and identify the downstream Ca2+ sensor of CRa. In this study, the spatial and temporal expression patterns of BraCRa were ...
