Abstract excerpt

KEY MESSAGE: A Gypsy LTR retrotransposon insertion in BrNYC1-A04 causes the stay-green phenotype of Chinese cabbage via bulked segregant analysis sequencing, fine-mapping, and gene silencing analysis. The stay-green trait positively influences the postharvest quality of Chinese cabbage (Brassica rapa L. ssp. pekinensis), a leafy vegetable crop in the Brassicaceae family. This trait is typically caused by defects...
