Large-scale population resequencing was applied for population structure analysis and gene flow detection. Genetic divergence between ancient tea trees and cultivated tea plants was compared.
Key Findings:
Genomic evidence confirms that Lincang in Yunnan is one of the core domestication regions of cultivated tea worldwide.
The genetic transmission route of ancient tea trees spreading from Lincang to surrounding production areas was clarified.
Selection genes associated with characteristic flavor compound synthesis in Lincang tea were screened to support selective breeding of high-quality Pu'er tea cultivars.
