Transcription factor gene induced by water deficit conditions and abscisic acid from Helianthus annuus, promoter and transgenic plants

A nucleic acid construct comprising a first nucleic acid molecule selected from the group comprising consisting of:

• (a) a nucleic acid molecule having the nucleotide sequence of SEQ ID NO:3;
• (b) a nucleic acid molecule having the nucleotide sequence of nucleotides 805 to 1221 of SEQ ID NO:3;
• (c) a nucleic acid molecule having a nucleotide sequence complementary to the nucleic acid molecule of (a) or (b);
• and
• a heterologous second nucleic acid molecule, wherein said first nucleic acid molecule is capable of promoting expression of the heterologous nucleic acid molecule in a transformed cell or tissue selected from the group consisting of bacterial, fungal, insect, plant, animal cell, embryogenic tissue, plant callus and plant seed.
