physiological function | Arabidopsis thaliana plants lacking NtrC tolerate high light intensities, display drastically elevated non-photochemical quenching component qE, have larger trans-thylakoid pH differences and have 10fold higher zeaxanthin levels under low and medium light intensities. A double-knockout mutant, lacking additionally photosystem II component PsbS, is devoid of qE. This double mutant grows faster than the NtrC mutant and has a higher chlorophyll content. The photosystem II activity is partially restored, and linear electron transport rates under low and medium light intensities are twice as high as compared with plants lacking NtrC alone | Arabidopsis thaliana |
