Ectopic Expression of , a Member of the OsDREB1 Subfamily, Confers Cold Stress Tolerance in Rice.

Plants adapt to adverse environmental conditions through physiological responses, such as induction of the abscisic acid signaling pathway, stomatal regulation, and root elongation. Altered gene expression is a major molecular response to adverse environmental conditions in plants. Several transcription factors function as master switches to induce the expression of stress-tolerance genes.
