Transgenic Plants Expressing A Mapkkk Protein Kinase Domain

Abstract

The invention features a method for increasing stress resistance or tolerance in a plant, the method including the steps of: (a) introducing into plant cells a transgene including DNA encoding a kinase domain of a mitogen-activated protein kinase kinase kinase (MAPKKK) operably linked to a promoter functional in plant cells to yield transformed plant cells; and (b) regenerating a transgenic plant from the transformed cells, wherein the kinase domain of said MAPKKK is expressed in the cells of the transgenic plant, thereby increasing the level of stress resistance or tolerance in the transgenic plant. The invention further features plants including a recombinant transgene capable of expressing a kinase domain of a mitogen-activated protein kinase kinase kinase (MAPKKK) or a kinase domain thereof, wherein the transgene is expressed in said plant under the control of a promoter that is functional in a plant cell.
