    摘要： A DNA sequence capable of encoding an enzyme protein which is the α-subunit of the first isozyme of rice anthranilate synthase (ASA); and a DNA capable of encoding an enzyme protein which is the α-subunit of the second isozyme of ASA. A transformant plant with a high tryptophan content can be regenerated by culturing vegetable cells into which a recombinant vector constructed by integrating a DNA fragment carrying the above DNA sequence into the downstream of a promoter has been transferred. The invention also provides a DNA having a promoter activity on the rice ASA gene, which is usable as a promoter for transferring a useful foreign gene into rice or other plants and then expressing the same.
