Contents
Annotated Information
- Os02g0731700 <=> Ghd2, OsBBX8, OsCCT09, OsK, OsK/Ghd2
Function
- Ghd2 functions as a regulator by integrating environmental signals with the senescence process into a developmental programme through interaction with different proteins
Expression
- Ghd2 is expressed mainly in the rice (Oryza sativa) leaf with the highest level detected at the grain-filling stage, and it is down-regulated by drought stress conditions.
Phenotypic analysis
- Overexpression of Ghd2 resulted in significantly reduced drought resistance, while its knockout mutant showed the opposite phenotype.
- The earlier senescence symptoms and the transcript up-regulation of many senescence-associated genes (SAGs) in Ghd2-overexpressing transgenicrice plants under drought stress conditions indicate that Ghd2 plays essential roles in accelerating drought-induced leaf senescence in rice.
- developmental and dark-induced leaf senescence was accelerated in the Ghd2-overexpressing rice and delayed in the ghd2 mutant.
