The rapeseed team cooperated with the bioinformatics team to reveal the adaptive evolution mechanism of clubroot disease resistance genes

Nanhu News Network News (Correspondent Yang Zhiquan Jiang Yingfen) Recently, the research results of the research team of Professor Zhang Chunyu and Professor Yang Qingyong of the rapeseed team of our school and the team of Professor Park Zhongyun of Shenyang Agricultural University were published in Plant under the title "R gene triplication confers European fodder turnip with improved clubroot resistance".

Clubroot, also known as "cruciferous cancer", is a soil-borne disease caused by the fungus Plasmodiophora brasicae, which usually causes massive tumor formation in crop roots that hinder crops Absorb nutrients and water from the soil, and in severe cases, the entire crop will die

The researchers selected ECD04 European turnip, which has multiple resistance loci, to resist clubroot disease.

Based on the above results, the study proposes an evolutionary model of Brassica crop clubroot resistance genes (Fig.

【English summary】

Clubroot is one of the most important diseases for many important cruciferous vegetables and oilseed crops worldwide.
