| Research Abstract |
High root temperature induces severe chilling injury in the leaves of rice seedlings. The first detectable event was the accumulation of nitrate and nitrite in the leaves, followed by the electron transport to be blocked between QA and QB in photosystem II. This was accompanied by the loss of thylakoidΔpH, malfunction of thermal dissipation, and over-reduction of photosystem II. Thus, the consequent generation of ROS and/or lipid peroxide should destroy the membranes such as thylakoid, chloroplast envelope, and cytoplasm, to lead to the leaf death.
