The Magic of Cytokinins: How They Power Plant Growth
Cytokinins are a group of plant hormones that act as cellular cheerleaders , promoting cell division, delaying aging, and ensuring lush, healthy growth. Found naturally in growing roots and shoots, these hormones are vital for plant development—and scientists harness their power in labs and farms worldwide. How Do Cytokinins Work? These hormones kickstart cell division (cytokinesis) by activating key proteins. They also slow down leaf aging, keeping plants green longer, and encourage shoot formation, making them essential for robust growth. Why Are Cytokinins Used in Tissue Culture? In tissue culture, cytokinins are the secret ingredient for multiplying shoots. Paired with auxins (which boost roots), they help regenerate full plants from tiny tissue samples—enabling mass production of identical, disease-free crops!
