Chemical Signalling in Plants

Many chemicals are critical for plant growth and development and in integrating various stress signals and controlling downstream stress responses by modulating gene expression machinery and regulating various pumps and biochemical reactions. Plant hormones are responsible for chemical signalling in plants. Auxin is the hormone responsible for phototropism in plants. The drought signalling in plants is done by Abscisic acid during the time when there is stress on water availability. Calcium signalling is one of the very important  intracellular second messenger molecules involved in many signal transduction pathways in plants. Nitric Oxide signalling is also an important chemical signalling adopted by plants for efficient utilisation of Nitrogen from the soil.
