Plant hormone functions at GPB 2027

Plant hormones, or phytohormones, are essential molecules that regulate a wide array of developmental and adaptive processes in plants. Key hormones include auxins, which drive root growth and cell expansion; cytokinins, which promote cell division and bud formation; gibberellins, which influence stem growth and seed germination; and abscisic acid, which regulates water balance and stress tolerance. Ethylene, another critical hormone, plays roles in fruit ripening and response to environmental stress. These hormones do not work in isolation but interact dynamically, enabling plants to respond to internal and external cues, optimizing growth, and preparing for challenges like drought or pathogens. Manipulating hormone levels in agriculture can support improved crop yields, enhance resilience, and enable control over processes like flowering and fruit maturation, making hormone study integral to modern farming strategies.
