Abstract excerpt

Heat tolerance of Arabidopsis thaliana (WT) and its mutants, crr2-2, lacking NADPH-dehydrogenase (Ndh-pathway), and pgr5, deficient in proton gradient regulation and/or ferredoxin-quinone-reductase (FQR-pathway), was studied from 30 to 46°C. Chlorophyll fluorescence revealed that thermal damage to photosystem II (PSII) was maximal in WT plants following short-term exposure of leaves to moderate or high...
