Cytokinin receptor AHK3 involved in senescence regulation of plant, mutant thereof and method for delaying senescence of plant using the same

摘要

The present invention is to encrypt talkie non-receptor AHK3, variants thereof or those between the involved in aging regulation of plants It is by using a polynucleotide to a method for delaying the senescence of plants. More specifically, the talkie non-receptor AHK3, the sequence number of 10 243 amino acid in the amino acid sequence of proline (proline) is a serine mutant is substituted with (serine) type between talkie non-receptor AHK3, and between an amino acid sequence of SEQ ID NO: 10 a polynucleotide encoding them using a method of delaying the senescence of plants. According to the invention AHK3 by over-expression by introducing a gene or a mutant gene in plants can delay the senescence of a plant, productivity of them through the plant and storage efficiency increase, and the like can be achieved .
