Summary

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 to low temperature and drought, which are the most prominent environmental cues impacting tea survival and productivity. Low temperature leads to winter dormancy through a complex network wherein genes related to cell rescue, defense, and chaperones were upregulated, and the genes associated with cell cycle and DNA processing were downregulated. A positive correlation with the oxidative stress and winter dormancy necessitated modulating oxidative stress for regulating winter dormancy. Chaperonic activities and oxidative stress have also been reported to play prominent roles in modulating drought response of tea. Importantly, drought stress impaired catechins accumulation by downregulating several genes of the pathway. It is a critical parameter with the background that catechins are one of the important components determining the quality of black tea. In the area of genome mapping, bulk segregant analysis followed by complete genotyping of pseudo-test progeny of two heterozygous parental clones for yield, drought, and other important traits identified 260 informative RAPD and AFLP markers. Transgenic tea has been developed by Agrobacterium and biolistic gun methods. Tea overexpressing osmotin is a success story that opened up a new path of developing tea plants with improved traits of choice. Developments in systems biology, next-generation sequencing, microRNAs, epigenetics, transcriptomics, metabolomics, proteomics, molecular markers, and transgenic technologies offer immense opportunities for understanding tea response to varied abiotic stresses followed by utilizing the outcome for tea improvement.
