Other claims from this paper (11)
- Intervention effect Mild arsenic stress significantly increased total amino acid content in both rice genotypes.
- Association The increase in total amino acids under mild arsenic stress was greater in the low arsenic accumulating genotype than the high accumulating genotype.
- Intervention effect At 10 μM, arsenite affected essential amino acids more than arsenate.
- Intervention effect Arsenate induced more proline accumulation than arsenite.
- Intervention effect Arsenic significantly induced histidine accumulation.
- Intervention effect Arsenic significantly induced aspartic acid accumulation.
- Intervention effect Arsenic significantly induced serine accumulation.
- Observation Glutamate kinase activity was inhibited in the high arsenic accumulating rice genotype.
- Observation Serine acetyltransferase activity increased.
- Observation Cysteine synthase activity increased.
- Association Increased enzyme activities were positively correlated with cysteine synthesis.
