Isolated DNA molecule encoding quinolate-phosphoribosil-transferase, DNA construct, plant cell and transgenic plant, peptide, process for preparing transgenic plant and method of reducing and increasing gene expression

摘要

An isolated DNA molecule comprising a sequence selected from the group consisting of: (e) SEQ ID NO: 1 (f) DNA sequences that encode an enzyme having the amino acid sequence of SEQ ID NO: 2 (g) DNA sequences that hybridize to the isolated DNA of ( a) or (b) above and which encode the quinolate phosphoribosyl transferase enzyme; and (h) DNA sequences that differ from the DNAs of (a), (b) or (c) above, due to the degeneracy of the genetic code and which encode the quinolate phosphoribosyl transferase enzyme, and constructs comprising said DNA. Ways to change quinolate phosphoribosyl transferase expression.
