Other claims from this paper (7)
- Intervention effect Under drought, a coordinated upregulation involving LEA proteins, proline and ABA metabolism was observed at the whole plant level.
- Intervention effect Drought stress significantly altered carbohydrate metabolism, direction not specified.
- Intervention effect Activation of a complete set of sucrose- and starch-degrading and -synthesising enzymes was detected under drought.
- Mechanism These enzymes act in concert with hexose and sucrose transporters to remobilise carbon throughout the plant system.
- Intervention effect A notable root-specific downregulation of ethylene synthesis was observed under drought.
- Intervention effect Under drought, raffinose and myo-inositol synthesis increased in leaves as carbon was redirected into distinct pathways.
- Intervention effect Under drought, malate pathway activation occurred in roots to relieve carbon flux in glycolysis.
