    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.

    摘要： In accordance with this invention, there is provided a DNA sequence which can encode an enzyme protein functioning as the rice dihydrodipicolinate synthase (DHDPS). One example of the DNA sequence according to this invention is the DNA having the nucleotide sequence shown in SEQ ID No. 1 of Sequence Listing. Additionally, this invention provides the DNA having the nucleotide sequence of SEQ ID No. 5, as well as the DNA having the nucleotide sequence of SEQ ID No. 7 of Sequence Listing, as the DNA which is capable of encoding the protein having the DHDPS activity. When cultivation is made of the plant cells in which there has been introduced a recombinant vector having carried therein a DNA fragment containing the DNA of this invention as inserted at downstream of the promoter of said recombinant vector, it is feasible to regenerate from said plant cells a transgenic plant having a high lysine content.

    摘要： A DNA encoding a phosphinothricin acetyltransferase protein obtained from Streptomyces sp. AB3534 strain is described which imparts a resistance to herbicides, particularly the herbicide phosphinothricin (PPT). Plants having a herbicide resistance are constructed by transforming a plant cell with DNA encoding the phosphinothricin acetyltransferase protein and then regenerating the transformed plant cell into a plant. A recombinant protein having the herbicide-resistant activity is also described.
