Abstract
The present disclosure describes genetically-modified plants having enhanced tolerance to multiple abiotic stressors, such as extreme temperatures (heat or cold) and/or drought. Abiotic stress tolerance is enhanced by ectopic expression of a heterologous glutaredoxin. Abiotic stress tolerance (particularly drought) is also enhanced by inhibited function, activity, or expression of an endogenous glutaredoxin. Methods of producing such genetically-modified plants are also disclosed.
Claims22
A genetically-modified plant having enhanced tolerance to an abiotic stressor as compared to a control plant, said genetically-modified plant having ectopic expression of a heterologous, abiotic stress tolerance gene, said gene encoding for a glutaredoxin.
-30. (canceled)
A fusion protein for enhancing the abiotic stress tolerance of a plant, said fusion protein comprising a glutaredoxin amino acid sequence linked to a reporter amino acid sequence by one or more peptide bonds.
A genetically-modified plant having enhanced resistance to an abiotic stressor, as compared to a control plant, said genetically-modified plant having inhibited expression, activity, or function of an endogenous glutaredoxin gene.
