Gene related to stress resistance of black cabbage and application of gene

The invention discloses a gene related to stress resistance of black cabbage and application of the gene, and relates to the technical field of genetic breeding, the stress is specifically high temperature, salt and drought, the gene is specifically a bHLH57 gene, and the nucleotide sequence of the gene is shown as SEQ ID NO.1. When related stress-resistant varieties are screened, the stress-resistant variety of the black cabbage is screened, and the stress-resistant variety of the black cabbage is screened. The bHLH57 gene expression quantity is detected only when the screened variety is planted to have six true leaves, wherein the stress resistance of the variety with higher bHLH57 gene expression quantity is stronger; the method provided by the invention can provide a guidance direction for culturing transgenic black cabbage varieties with stress resistance. 本发明公开了一种与乌菜抗逆性相关的基因及其应用，涉及遗传育种技术领域，其中所述逆性具体为高温、盐和干旱，所述基因具体为bHLH57基因，其核苷酸序列如SEQ ID NO.1所示，在对相关抗逆性品种进行筛选时，只需将筛选品种种植至6片真叶时进行bHLH57基因表达量的检测，其中bHLH57基因表达量越
