Assessing the relationship between respiratory acclimation to the cold and photosystem II redox poise in Arabidopsis thaliana
We examined the effect of manipulating photosystem II (PSII) redox poise on respiratory flux in leaves of Arabidopsis thaliana. Measurements were made on wild-type (WT) plants and npq4 mutant plants deficient in non-photochemical quenching (NPQ). Two experiments were carried out. In the first experiment, WT and mutant warm-grown plants were exposed to three different irradiance regimes [75, 150 and 300 μmol photosynthetically active radiation (PAR)], and leaf dark respiration was measured in...[Show more]
