WebOne cytokinin is 6-furfurylaminopurine (kinetin); other compounds derived from adenine with effects similar to those of kinetin, and certain compounds derived from another nitrogen-containing compound, urea, are conveniently referred to as cytokinins, although not all are natural products. WebPhytohormones are plant hormones. They are organic substances that facilitate regulating the growth of a plant and its development. Plant hormone signals are incorporated at the gene-network level, and their signaling pathways act non-redundantly. Examples are auxin, gibberellins, cytokinins.
