    摘要: A DNA sequence is provided, which encodes an enzyme that is the &agr;-subunit of the first isozyme of rice anthranilate synthase (ASA). Transformed plants having a high tryptophan content can be regenerated by culturing the plant cells having introduced therein such a recombinant vector which contains, at a position downstream of a promoter, an inserted DNA fragment carrying the above DNA sequence. In addition, methods of selecting transformed plant cells are disclosed, wherein plant cells transformed with the discloses DNA are resistant to inhibitory concentrations of tryptophan or tryptophan analogues.
