Other claims from this paper (10)
- Mechanism DHAR follows a ping-pong reaction involving DHA and GSH to promote AsA generation under salt stress.
- Mechanism H2O2-mediated sulfenylation inhibits the reported DHAR mechanism.
- Intervention effect PbDHAR3 overexpression alleviated salt-induced damage in pear callus and Arabidopsis plants.
- Intervention effect Silencing PbDHAR3 decreased salt tolerance in Pyrus betulaefolia.
- Intervention effect PbNAC3 overexpression improved salt tolerance in pear callus.
- Intervention effect PbNAC3 silencing reduced salt tolerance in P. betulaefolia.
- Intervention effect PbNAC3 overexpression adjusted the growth–salt stress trade-off in Arabidopsis.
- Observation NCED and PYL expression levels were higher under salt treatment.
- Observation ABA content was higher under salt treatment.
- Mechanism PbNAC3 activates PbNCED5 through cis-regulatory element interaction.
