Stain-resistant gene Di19 and application thereof in rape stain-resistant breeding
By overexpressing the Di19 gene in rapeseed, the problem of insufficient stain resistance of rapeseed under stain stress was solved, and the stain resistance of rapeseed was significantly improved during the germination period and the high-quality development of the rapeseed industry was promoted.

AI Technical Summary
In the prior art, rapeseed is susceptible to hypoxic stress and ionic poisoning when facing stain damage stress, which affects its underground root development and above-ground plant growth. At the same time, the disease resistance is weakened, easy to fall, and the oil content of seeds is reduced, which restricts the development of the rapeseed industry.
By overexpressing the Di19 gene in rapeseed, the Di19 gene was transferred to rapeseed by Agrobacterium transformation method, which improved the stain resistance of rapeseed.
It significantly improves the stain resistance of rapeseed during the germination period and can take root and emerge normally in a flooded anaerobic environment. Compared with wild-type rapeseed, the germination rate is 12.6 times to 27 times.
