Cytokinin discovery
Web150 8.3K views 1 year ago Cytokinins (also known as kinetin) are a class of plant compounds that promote cell division or cytokinesis, in plant roots and shoots. They … WebZeatin is a cytokinin derived from adenine, which occurs in the form of a cis - and a trans - isomer and conjugates. Zeatin was discovered in immature corn kernels from the genus Zea. It promotes growth of lateral buds and when sprayed on meristems stimulates cell division to produce bushier plants. [citation needed] Occurrence [ edit]
