Cytokinins are one of the major groups of plant hormones . They stimulate anabolic processes , growth and cell division . The first was discovered cytokinin kinetin , or N-6 furfuryloadenina . Kinetin is an important component of the metabolic pathway that allows the cell to get rid of excess free radicals. This is in response to oxidative stress . The plant cells in the cytosolic fraction , and microsomal membranes are thylakoid cytokinin binding proteins - CBP ( Cytokinin called Binding Protein ) . Binding of them referred to cytokinin induces a physiological response .

Traumatic acid – trans-2-dodecenedioic acid – is synthesized in plant tissues from polyunsa- turated fatty acids, linolenic (18:3) and linoleic (18:2) in response to wounding, pathogenes attack and herbivores. The key enzymes in the biosynthesis pathway of TA are lipoxygenases (LOXs) and hydro- peroxide lyase (HPL). From the numerous investigations it appears that this compound stimulates the cell divisions, wound healing and callus formation. Moreover, TA causes the increase of the content of photosynthetic pigments, monosaccharides and water-soluble proteins in plants’ cells.

Cytokinins are plant hormones that stimulate the division and differentiation of cells. In the last decade , genetic and molecular analysis of mutants has provided a valuable contribution to the understanding of the molecular mechanism of action of this class of hormones. In this paper summarizes the results of research to know the ingredients and the principles of perception and functioning of the cytokinin signal transduction pathway in a plant cell .
