Abstract: Disclosed is 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. Regulated is the development of phloem, which plays the 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 an effect of controlling the size and storage capacity of the plant storage organ. The development of phloem can be 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.

Abstract: The present invention relates to, inter alia, a gene which increases biomass production isolated from Arabidopsis thaliana, and a method for producing a transgenic plant by using same. More specifically, the present invention provides, inter alia, a composition, a recombinant expression vector and a transgenic plant for increasing plant biomass production, comprising a base sequence coding for the amino acid sequence of sequence number 2. Consequently, by using the gene for increasing biomass production of the present invention, it is possible to obtain a transgenic plant with which the amount of biomass production is increased and, ultimately, it is expected that same can be used in order to increase starting materials for the pulp and papermaking industries, and starting materials for bioethanol.

Abstract: The invention generally features methods for increasing yield, shoot formation, and delaying senesence in plants with the use of transgenes that regulate the cytokinin response. The invention also features plants and plant components that harbor the transgene(s).
