Cytokinins are a class of plant hormones that play a crucial role in plant growth and development. They are primarily involved in promoting cell division, also known as cytokinesis, which is essential for the formation of new tissues and organs. Cytokinins are synthesized mainly in the root tips and are then transported upwards to other parts of the plant, such as shoots, leaves, and fruits. Their effects are widespread, influencing processes like bud formation, leaf senescence, and the delay of fruit ripening. In conjunction with another major plant hormone, auxin, cytokinins regulate the differentiation of plant cells, determining whether they develop into roots or shoots. The balance between cytokinin and auxin levels is a key factor in controlling plant morphology. Naturally occurring cytokinins are adenine derivatives, with zeatin being a prominent example. Synthetic cytokinins are also widely used in agriculture and horticulture to improve crop yields and plant propagation. Research continues to explore the complex mechanisms by which cytokinins interact with other plant signaling pathways to orchestrate a plant's overall growth and response to environmental stimuli. Their fundamental role in cell division makes them indispensable for plant life.
