Other claims from this paper (13)
- Intervention effect Sulfur deficiency severely affected the rice photosynthetic apparatus.
- Intervention effect Sulfur deprivation reduced chlorophyll content by 49%.
- Intervention effect Sulfur deprivation generally reduced PSII, PSI, and their associated light-harvesting antenna.
- Intervention effect PSII efficiency at growth light was 31% lower under sulfur deprivation.
- Intervention effect PSI photoreduction of NADP+ decreased by 61% under sulfur deprivation.
- Intervention effect Rubisco content was significantly reduced in sulfur-deprived plants.
- Mechanism Imbalances in photosystems and carbon fixation led to over-reduction of electron carriers.
- Intervention effect Monosaccharide levels were lower in sulfur-deprived plants.
- Intervention effect Starch content was higher in sulfur-deprived plants.
- Intervention effect GSH level was 70% lower under sulfur deprivation.
- Intervention effect The redox state was significantly more oxidized.
- Mechanism Altered GSH status upregulated cytosolic GSH reductase and monodehydroascorbate reductase isoforms.
- Intervention effect Flavonoids and anthocyanins increased in sulfur-deprived plants.
