title: A shared response of thaumatin like protein, chitinase, and late embryogenesis abundant protein3 to environmental stresses in tea [Camellia sinensis (L.) O. Kuntze].
abstract: Drought poses a significant threat to tree plants including tea [Camellia sinensis (L.) O. Kuntze] that yields a popular beverage "tea." Consequence of drought is heat and salt stress, for which data on molecular response in tree species are not available. The present work analyzed drought-responsive subtracted cDNA libraries of tea to identify drought-responsive genes. Temporal and spatial gene expression suggested the involvement of chaperones as one of the major mechanisms to protect the plant against drought-related damages. A common response of thaumatin like protein, chitinase, and late embryogenesis abundant protein3 across four stresses suggests these to be useful targets to generate "drought stress proof" tea.
