Overexpression of AtCAMTA5 enhances drought tolerance in Arabidopsis.

The Overexpression of AtCAMTA5 leads to higher plant weight and seed weight as compare to Col-0. Under drought condition overexpression lines had reduce water loss,high water use efficiency decline in photosynthesis contributes to 95% survivability wherase Col-0 and camta5 showed enhance sensitivity.Microarray analysis revealed that AtCAMTA5 regulates genes enriched with CAMTA recognition motif like ANAC19, SPL16, aminotransferase, chitinase, MAPK7, SnRK2.2, E3-ligase, RUBISCO, PSI and PSII, etc which were involved in stress response, development, protein modification and photosynthesis.
