BSA-seq Analysis of the Stay-green Trait in Chinese Cabbage (Brassica rapa L. ssp. pekinensis)
The stay-green trait positively influences the postharvest quality of Chinese cabbage (Brassica rapa ssp. pekinensis), a leafy vegetable crop in the Brassicaceae family. This trait is typically caused by defects in chlorophyll degradation. A candidate interval associated with the stay-green phenotype in Chinese cabbage was identified through BSA-seq and fine-mapping analyses.
