All kinds of abiotic stress factors are probably the most limiting for crop quality and productivity, comprising economical output and human food supply. Plants constantly monitor their surroundings and make appropriate metabolic, structural and physiological adjustments to accommodate environmental changes. Within frame work of genetic background, plant productivity is dependent on this constant adjustment of gene expression in response to environmental cues. The genome-environment interaction is an essential focus for the elucidation of the nature of the phenotypic variations leading to successful stress tolerance responses. Today, the role of organic chemicals and inorganic chemicals are recently emerged and also, widely used approaches for stress mitigation in plant systems. All these molecules modify constitutively expressed transcription factors, leading to the expression of early response transcriptional activators, which then activate downstream stress tolerance effector genes, responsible for stress mitigation. This review explains the role of few organic and inorganic chemicals in stress mitigation. Also, there are obviously still large gaps to fill in order to elucidate the precise role of these chemicals in enhancing the tolerance of plant to environmental stresses during development as well as normal conditions.
