Plant Signaling and Chemical Signaling

Plant signaling is the capacity of plants to detect and react to the earth to change their morphology, physiology and phenotype in like manner. Different subdivisions, for example, plant physiology, nature and atomic science are used to examine the capacities of the plant. Plants respond to chemicals, gravity, light, dampness, contaminations, temperature, oxygen and carbon dioxide focuses, parasite pervasion, malady, physical disturbance, sound and touch.

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 signaling in plants. Auxin is the hormone responsible for phototropism in plants. The drought signaling in plants is done by Abscisic acid during the time when there is stress on water availability. Calcium signaling is one of the very important intracellular second messenger molecules involved in many signal transduction pathways in plants. Nitric Oxide signaling is also an important chemical signaling adopted by plants for efficient utilization of Nitrogen from the soil.
