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 .

The mature female mammal ovary extends continuously follicular development process, which is an expression of proliferation and differentiation of cells. Gene expression occurs in the ovary in a specific order based on many factors. It is known that some proteins are expressed at a specific stage of follicular development and corpus luteum luteinisation. Hormones regulate many functions are ovarian steroids, so the distribution of the receptors of these hormones is extremely important.
