The physiological role of ascorbate as photosystem II electron donor: protection against photoinactivation in heat-stressed leaves.

Plant physiology - 1 May 2011

Tóth Szilvia Z, Nagy Valéria, Puthur Jos T, Kovács László, Garab Gyozo

Abstract excerpt

Previously, we showed that ascorbate (Asc), by donating electrons to photosystem II (PSII), supports a sustained electron transport activity in leaves in which the oxygen-evolving complexes were inactivated with a heat pulse (49°C, 40 s). Here, by using wild-type, Asc-overproducing, and -deficient Arabidopsis (Arabidopsis thaliana) mutants (miox4 and vtc2-3, respectively), we investigated the physiological role...
