The function of TaDREB1 transcription factor, a product of TaDREB1 gene, is regulation the expression of obiotic stress-tolerant genes, such as drought-tolerant genes. Using the theory and methodology of molecular biology, to understand the molecular mechanism of crop drought tolerance and to discover novel drought-tolerant gene resources are not only important in theory but also valuable in practice for breeding drought-resistant and high yield variety and promoting the development of economizing water in ...
