ABSTRACT
Respiration is a ubiquitous process involved in the oxidation of carbohydrates through glycolysis and Krebs’s cycle, and is responsible for the emergence of life on this planet. Respiration is important for the acclimation of plants against different types of abiotic stress such as drought, salinity, extreme temperature, which brings changes in the energy levels as well as energy requirements of plants, eventually inducing the changes in the respiration process. Plants are autotrophic organisms capable of using sunlight for splitting of water molecules, reduction of carbon dioxide and finally storing food reserve as insoluble polysaccharides or for their utilization in the synthesis of other compounds. Respiration plays a pivotal role in the acclimation of plants to environmental stress especially in conferring tolerance to the abiotic stress factors including drought, flood, high, low temperature, salinity. Plants, being sessile, have to cope with various abiotic stresses such as drought, salinity, extreme temperatures, etc. that may act on the plant systems internally or externally.
