Plant Metabolism and Stress Signalling

Plant metabolism is defined as the complex of chemical and physical events of respiration, photosynthesis, and the synthesis and degradation of organic compounds. These metabolic pathway allows the organism to perform all the normal life processes such as growth and maintenance of cell structures, repair damage, reproduction and respond to environment. The enzymatic activity of plants is controlled by allosteric sites by which modulator or effectors binds to it. 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.
