Other claims from this paper (7)
- Observation Free and conjugated polyamine levels were higher in tolerant than in sensitive rice callus under non-stressed conditions
- Observation Arginine decarboxylase and polyamine oxidase activities were higher in tolerant than in sensitive rice callus under non-stressed conditions
- Observation Under heat stress, the uncommon polyamines norspermidine and norspermine were detected in cultivar N22 and increased appreciably
- Observation Norspermidine and norspermine were not detected in callus of cultivar IR8
- Intervention effect Arginine decarboxylase and polyamine oxidase activities increased to a larger extent in N22 than in IR8 callus during heat stress
- Association Arginine decarboxylase and polyamine oxidase activities were well correlated with the increased levels of common and uncommon polyamines
- Association Increased transglutaminase activity indicates a high titre of conjugated polyamines
