Cyclic electron flow plays an important role in protection of spinach leaves under high temperature stress

Cyclic electron flow plays an important role in protection of spinach leaves under high... Heat stress is one of the major abiotic stresses and affects plant productivity in a negative manner.

Abstract

Heat stress is one of the major abiotic stresses and affects plant productivity in a negative manner. Photosynthetic processes are largely influenced by heat stress. In spinach (Spinacia oleracea L.) leaves at 40°C the decrease in PSII activity was mainly due to the decreased efficiency to capture excitation energy, increased yield of regulatory energy dissipation mechanism Y(NPQ), and decreased quantum yield Y(II). According to the results below 45°C PSI is stable and protected while at a higher temperature stability of PSI was reduced and protection was not sufficient. Therefore, we conclude that cyclic electron flow plays an important role in protecting PSI from heat stress.
