Different mitigation approaches against abiotic stress conditions: field implications

Abiotic Stress Tolerance in Plants

Аннотация

Horticulture crop production is low due to fluctuations in climate change. Abiotic stresses showed adverse effects on the productivity of plants. Abiotic stresses involved in horticulture crops losses regarding germination, vegetative growth, reproductive phase, and quality of produce. Plants modulate physiological and biochemical indices to mitigate adverse effects of abiotic stresses. Recently, there has been a lot of interest in the integration of different stress mitigants to lessen the adverse effects of abiotic stress. Different stress mitigants had potential to enhance the tolerance against abiotic stresses by promoting root growth, leaf transpiration, germination of seeds, and antioxidant levels while decreasing the over-generation of toxic substances. The current review explores the important roles played by signaling molecules, phytohormones, and plant growth-promoting rhizobacteria (PGPR) in horticulture plants to ameliorate abiotic stress tolerance. Therefore, the goal of this study is to provide an overview of the evolving ideas around the function of important particulates in abiotic stress tolerance focusing on the productivity of horticultural crops. Moreover, it also describes the various roles of different stress mitigants utilized in plants under stress conditions. Therefore, it has been concluded that the contribution of different stress mitigants such as signaling molecules, phytohormones, and PGPR can ameliorate abiotic stress tolerance in horticulture crops.
