Tea: Present Status and Strategies to Improve Abiotic Stress Tolerance

摘要: Tea (Camellia sinensis (L.) O. Kuntze) is sensitive to several abiotic factors including low temperature, drought, frost, hail, and waterlogging. The published work largely relates temperature which are the most prominent environmental cues impacting tea survival productivity. Low leads winter dormancy through a complex network wherein genes related cell rescue, defense, chaperones were upregulated, associated with cycle DNA processing downregulated. A positive correlation oxidative stress necessitated modulating for regulating dormancy. Chaperonic activities have also been reported play roles in drought response of tea. Importantly, impaired catechins accumulation by downregulating pathway.
