Title
Exogenous methylglyoxal alleviates drought-induced ‘plant diabetes’ and leaf senescence in maize
Yi-Hsuan Lin; Ya-Ning Zhou; Xiao-Gui Liang; et al. Journal of Experimental Botany 2023. doi:10.1093/jxb/erad503
Other claims from this paper (7)
- Intervention effect Exogenous MG delayed leaf senescence and promoted photoassimilation under drought.
- Intervention effect Exogenous MG reduced drought induced yield loss by 14%.
- Mechanism Drought increased sugar accumulation in leaves through inhibited sugar transporters.
- Mechanism Drought led to glycolysis disequilibrium and endogenous MG overaccumulation.
- Intervention effect Exogenous MG upregulated glycolytic flux and the glyoxalase system.
- Observation Drought promoted trehalose-6-phosphate anabolic gene expression and suppressed catabolic gene expression.
- Intervention effect Exogenous MG reversed drought effects on trehalose-6-phosphate related genes.
