Mitogen mode of action is not entirely clear. It is known tRNA with anticodon adjacent where there cytokinin in the process of protein synthesis, they are involved in the linker tRNA and mRNA ribosome complex. But this may not be the mode of action of exogenous cytokinin. Because tRNA, the cytokinin synthesis is changed from the original in tRNA produced in purine. Exogenous cytokinins did not participate in the tRNA, cytokinin wholesale, but can promote nitrate reductase, protein and nucleic acid synthesis. Between the cytokinin signal transduction pathway and other signal transduction pathways intersect hyperactive response, mitogen plant sale, while cytokinin receptor and its downstream evident in a number of key components of functional redundancy phenomenon. Therefore, , the key to solving these problems illustrate the cytokinin signal transduction networks. cytokinins on cell proliferation plays an important regulatory role, Hanting mitogen in cell cycle G1 / S phase, cytokinin promote the expression of D-type cyclins CycD; and in the G2 / M phase, cytokinin, its role and the CDK phosphorylation. Plants on the body by metabolic cytokinin cytokinin levels, regulating plant growth regulatory genes, affect plant root tips, shoot tips and other organs of growth and development.
