physiological function | chloroplast-localized adenosine-5'-phosphosulphate reductase (APR) generates sulfite and plays a pivotal role in reduction of sulfate to cysteine. The increases in APR activity in response to sulfite infiltration into wild-type and sulfite oxidase (SO)-deficient mutant leaves result in an increase in endogenous sulfite, indicating that APR has an important role in sulfite-induced increases in stomatal aperture. The importance of APR and SO and the significance of sulfite concentrations in water loss are further demonstrated during rapid, harsh drought stress in root-detached wild-type, gr2 and SO transgenic plants. Effects of sulfite infiltration on water status and sulfite accumulation in wild-type and sulfite oxidase overexpressing and deficient mutant leaves, overview | Arabidopsis thaliana |
