Auxins are a class of Plant Growth Substance (often called Phytohormone s or Plant Hormone s). Auxins play an essential role in coordination of many growth and behavioral processes in the plant life cycle. OVERVIEW Auxins, the first hormones to be discovered, have been demonstrated to be a basic coordinative signal of plant development. Their pattern of active transport through the plant is complex, and auxins typically act in concert with (or opposition to) other Plant Hormone s. For example, the ratio of auxin to Cytokinin in certain plant tissues determines initiation of root versus shoot buds. As a result, a plant can (as a whole) react on external conditions and adjust to them, without requiring a Nervous System . The most important member of the auxin family is Indole-3-acetic Acid (IAA). It generates the majority of auxin effects in intact plants, and is the most potent native auxin. However, molecules of IAA are chemically labile in aqueous solution, so IAA cannot be applied commercially as a plant growth regulator.
