KINASE RELATED TO SIGNAL TRANSDUCTION OF GIBBERELLIN AND GENE THEREOF

摘要

PURPOSE: A kinase related to the signal transduction of gibberellin, the type of phytohormone and a gene encoding the kinase are provided which are useful in regulating physiological function of gibberellin. CONSTITUTION: A kinase, NtDSK1, is isolated from cytoplasm of Nicotin tabacum. The kinase has dual specificity phosphorylating residues of serine, treosine or tyrosine and promotes gene expression regulated by gibberellin or related thereto in the maturation of stamen and the seed thereof, and has amino acid sequence and nucleotide sequence represented by SEQ. ID. NO:1 and SEQ. ID. NO:2, respectively. And plasmid vector pNtDSK1(KCTC 8917P) comprising cDNA gene of the kinase. Consequently a recombinant plant having modified signal transduction of gibberellin is prepared by using E. coli transformed with the plasmid vector pNtDSK1 having kinase genes.
