20150240251 | COMPOSITION FOR REGULATING FLOWERING OF A PLANT CONTAINING THE GENE CODING FOR ABI3 PROTEIN - Provided are a composition containing ABI3 gene and a method of delaying flowering of plants using the same. The method has an excellent effect on delaying of flowering of plants. In the previously known method of delaying the flowering of plant, since flowering is delayed by silencing the expression of a gene for promoting flowering, it is difficult to regulate a degree of delaying of flowering. Also, since a gene silencing method such as RNAi is used, it is not easy to produce an actual transgenic plant and thus it is difficult to use for industry. However, ABI3 gene acts in a manner which delays flowering when expression increases, and thus it is easy to regulate the degree of delay in flowering and to produce a transgenic plant. Thus, it is expected that the present disclosure can be effectively applied to increase the productivity of crops by delaying flowering time or blocking flowering in plants of which vegetative tissue or leaves are used. | 08-27-2015 |
