Other claims from this paper (10)
- Observation ACC synthase activity in stressed wheat leaves increased continuously throughout the 48 h of water stress treatment.
- Observation Ethylene production decreased continuously as water stress progressed in cultivar 8139.
- Observation Ethylene production in cultivar 504 increased remarkably early and decreased later as water stress progressed.
- Observation The decrease in leaf relative water content under water stress was greater in drought-sensitive cv. 8139 than in drought-resistant cv. 504.
- Observation Changes in ACC and MACC levels and ACC synthase activity were higher in drought-sensitive cv. 8139 than in drought-resistant cv. 504 during water stress.
- Intervention effect MGBG, an inhibitor of SAMDC, significantly altered ACC and MACC levels, ACC synthase activity and ethylene production in stressed leaves of both cultivars, increasing them.
- Intervention effect AOA, an inhibitor of ACC synthase, significantly altered ACC and MACC levels, ACC synthase activity and ethylene production in stressed leaves of both cultivars, reducing them.
- Mechanism The authors concluded that ethylene production level in plants did not depend on the ACC level during water stress.
- Mechanism The authors suggest the early increase in ethylene in the drought-resistant cultivar during water stress might be an adaptation to water stress.
- Mechanism The authors conclude that MACC played its role primarily in regulating ethylene production under water stress.
