Adenine cytokinin is a class of substances can promote cell division. In the process of plant tissue culture, growth and differentiation of callus by auxin and cytokinin regulated in different proportions. Cytokinin may induce callus promote cell division, chloroplast development and stem bud formation; also regulates biological processes of plant growth and development of plant mitogen various periods, such as the delay leaf senescence. Cytokinins (2 mg · L-1KT or 4 mg · L-1KT) four days after the treatment, a large number of deaths Ningde mitogen, culture brownish black; extraction of total DNA, agarose gel electrophoresis, the results show: 2 and 4 mg · L-1KT two treatments have significant size of 140 ~ 180 bp fragment and multiply the amount of DNA 'ladder' (DNA Ladder) were PI and FDA staining microscopic observations can be seen:. 2 mg · L -1KT handle most cell nuclei smaller plant cytokinin wholesale, nuclear chromatin condensation plant mitogen price, was bar or meniscus; cytoplasm condensed, there asymmetrical Plasmolysis and loss of FDA dyeing activity of these results indicate that the high concentration of cytokinin treated cotton suspension cells caused mass death is a manufacturer of PCD cytokinin |.
