Abstract excerpt
The npq1 mutant of Arabidopsis thaliana (L.) Heynh. has no xanthophyll cycle due to a lack of functional violaxanthin de-epoxidase. Short-term exposure (<2 days) of detached leaves or whole plants to the combination of high photon flux density (1,000 micromol m(-2) s(-1)) and low temperature (10 degrees C) resulted in PSII photoinhibition which was more acute in npq1 than in the wild type. This increased...
