  • Use of active cytokinin synthase gene
    Patent number: 8962920
    Abstract: Cytokinin is a plant hormone that regulates various physiological activities including cell division, cell cycle, cellular senescence, and axillary buds outgrowth. The present invention provides a method for producing a transformed plant by introducing an isolated nucleic acid or recombinant vector containing the isolated nucleic acid into a plant cell such that the amount of active cytokinin synthesized from nucleotide cytokinin is increased in the plant cell and by regenerating a plant body from the plant cell.
    Type: Grant
    Filed: January 13, 2012
    Date of Patent: February 24, 2015
    Assignee: Riken
    Inventors: Hitoshi Sakakibara, Nanae Ueda, Takeshi Kuroha
  • METHOD FOR INCREASING PLANT BIOMASS BY CONTROLLING ACTIVE CYTOKININ EXPRESSION LEVEL
    Publication number: 20130212743
    Abstract: An object of the present invention is to provide a means for conferring a useful phenotype to a plant by efficiently controlling the quantitative productivity of iP-type and tZ-type active cytokinins in plant aerial organs. According to the present invention, a method for increasing plant biomass by causing the overexpression of an active cytokinin synthase gene and a cytokinin hydroxylase gene in a plant body is provided.

  • Use of active cytokinin synthase gene
    Patent number: 8124834
    Abstract: It is an object of the present invention to clarify an enzyme gene capable of directly regulating the amount of active cytokinins synthesized and to provide a transformed plant with a regulated amount of cytokinins using the aforementioned gene.
