Abstract
Polyamines are the organic molecules present in all living organisms and are involved in various metabolic activities. Polyamine plays a key role in diverse plant functions such as flowering, embryogenesis, cell division, seed germination, and senescence. In addition, polyamines play a vital role to protect the plant from various abiotic stresses. Changing environmental factors aggravate the yield losses in many crops and substantial crop losses in many countries. Abiotic stresses negatively impaired the plant function and cause physiological, morphological, and biochemical alterations to the plant. Therefore, adoption techniques are essential to ensure sustainable crop production. Hence utilizing the polyamines for abiotic stress is ensuring a successful crop production. Exogenous application of polyamines alleviates the cold, temperature, oxidative, drought, salt, and UV stress in various crops.
