Abstract

The global population is increasing day-by-day, simultaneously; crop production needs to increase proportionately. Environmental stress also known as abiotic stress conditions such as drought, heat, salinity, cold, or pathogen infection can have a devastating impact on plant growth and yield under field conditions. Mechanisms that protect against abiotic stress are essential for plant survival, for growth and productivity, is particularly very important for agriculture. Whereas, increase crop production being restricted due to abiotic and biotic stresses, abiotic stresses adversely affect crop growth and development, leading to crop loss globally and thereby causing a huge amount of economic loss as well. Since last many years, advancement and modern developments in plant physiology, genetics and molecular biology improve our understanding in plant responses to abiotic stress condition. Plants can overcome environmental stresses either by chemical priming or by activating molecular networks including signal transduction, stress perception, metabolite production, and expressions of specific stress-related genes. Regulation of functional genes and increase stress tolerance of plants can be enhance by chemical priming agents as well as genetic engineering. This review summarizes the major abiotic stress, its response on plants and major achievements in molecular approaches that can potentially enhance and induce the abiotic stress tolerance in plants.

Keywords: Abiotic stress, tolerance, molecular approach, chemical priming, plant responses.
