The present invention provides isolated HaHB11 polypeptides and nucleic acids encoding the same. Also provided are methods of introducing a nucleic acid encoding HaHB11 polypeptides into a plant cell, plant part or plant, e.g., to increase tolerance to abiotic stress, to delay development and/or prolong the life span of a plant, and/or to increase yield from the plant. The invention also provides nucleic acids comprising HaHB11 promoter sequences and methods for expressing a nucleotide sequence of interest operably associated with the HaHB11 promoters of the invention in a plant cell, plant part, or plant. Also provided are transformed plants, plant tissues, plant cells and plant seed comprising the nucleic acids, expression cassettes and vectors of the invention.

HaHB11 provides improved plant yield and tolerance to abiotic stress

A polynucleotide having at least 80% sequence identity with the full-length nucleotide sequence of SEQ ID NO: 1 and substantially identical polynucleotides; an isolated polypeptide having at least 80% sequence identity with the full-length amino acid sequence of SEQ ID NO: 2 and substantially identical polypeptides; and polynucleotides encoding the Ha WRKY76 polypeptide and substantially identical polypeptides are described. Also described are vectors and recombinant expression cassettes containing the c DNA polynucleotide, a polynucleotide encoding the Ha WRKY76 polypeptide, or substantially identical polynucleotides. Transgenic plants containing such expression cassettes, related methods and uses are also provided.
