B-09 Regulatory Genes for Plant Differentiation and Growth

技术优势

● The novel GA binding proteins are helpful in increasing the GA sensitivity to enhance plant growth. ● Tall crop plants such as grain crops can be modified into dwarf types by suppressing the expression of the proteins. The lodging can be reduced to improve the yield.● The novel protein can be used to assess the binding to biologically active GA.　Compounds that regulate GA actions on plants can be screened and tested.

*Abstract

Researchers at Nagoya University successfully isolated multiple GA-insensitive dwarf mutants in rice and identified the causative gene, GA insensitive dwarf mutant-1; GID1. In addition to finding that GID1 protein to be a cytoplasmic receptor that mediates GA signaling, the researchers identified genes and GA-binding proteins involved in GA signaling.

Summary: The protein (P1) is useful in assay method of gibberellin responsiveness, for selecting compound that controls gibberellin response, and for selecting compound that controls interaction of gibberellin and protein (P1). The nucleic acid encoding the protein (P1) is useful for producing plant exhibiting increased sensitivity with respect to gibberellin. The vector (V1) is useful for producing plant exhibiting decreased sensitivity with respect to gibberellin. The nucleic acid encoding the protein (P1) or the vector (V1) is useful for decreasing or increasing gibberellin sensitivity in plants (all claimed), and for controlling differentiation/growth of plant. The nucleic acid encoding the protein (P1) or the vector (V1) is useful for preparation of ornamental plants having aesthetic value, and for production of plants exhibiting reduced height, thus exhibiting resistant to lodging and increasing the yield of agricultural product.
Novelty: Novel protein exhibiting binding ability with gibberellin, useful in assay of gibberellin responsiveness, and for controlling differentiation or growth of plant
