Plant Hormones
Plant hormones are chemical signals that regulate important biological processes such as growth, development, and response to environmental changes. These hormones work like mediators that dictate when a plant’s cells should divide and when they should die; when they should accumulate starch or store water; and when they should respond to light or gravity. Plant hormones also influence how cells organize themselves into organs and how organs interact with each other. By modulating these processes, plant hormones are responsible for a large number of phenomena. For example, they are essential for a plant to know when to flower, stop growing, or enter dormancy. They are also critical for the abiotic stress responses of plants to hostile conditions such as drought and cold. Additionally, certain synthetic plant hormones are used in agriculture to improve productivity, reduce crop losses due to pests and diseases, and ameliorate the growth of plants under stress conditions.
