Description The response of Camellia sinensis (L.) O. Kuntze cultivars Chinary and Assamica to Cu and Al stresses was
investigated. Exposure to 100 μM CuSO4 or 100 μM AlCl3 led to accumulation of reactive oxygen species (ROS) more
in Assamica than in Chinary. Proline content was higher in Chinary compared to Assamica, while chlorophyll and
protein contents decreased upon Cu and Al exposure in both the cultivars. Expression of glutathione biosynthetic
enzymes γ-glutamylcysteinyl synthetase (γ-ECS) and glutathione synthetase (GSHS) was elevated. Phytochelatin
synthase (PCS), an enzyme involved in phytochelatins synthesis by using glutathione as a substrate was up-regulated at
its transcript level more in Chinary than in Assamica. These results suggest that Chinary could be more tolerant than
Assamica.
