PHD GENE INVOLVED IN DEVELOPMENT AND FORMATION OF PLANT PHLOEM

摘要

The present invention relates to: a PHD protein regulating the differentiation of plant phloem; a recombinant vector containing a gene encoding the same; a plant transformed with the recombinant vector; a seed of the plant; and a method for regulating the development and formation of plant phloem by using the gene encoding the PHD protein. The present invention regulates the development of phloem, which plays the most important role in moving a photosynthetic product and finally storing the same in starch and sugar forms in a plant storage organ, so as to regulate the function of phloem, thereby having a remarkable effect of controlling the size and storage capacity of the plant storage organ. In addition, according to the present invention, the development of phloem can be remarkably improved by allowing the PHD gene to be silent in plants, and thus it is expected that the function of plant phloem can be increased through the regulation of PHD gene expression by using genetic engineering techniques.
