Introduction: Climate change, which reduces the efficiency of agricultural products, is a major challenge for food security. Abiotic stresses such as drought, salinity, heat and cold cause many changes in the physiological, biochemical and molecular processes of plants. By knowing the role of proteins expressed in response to stress, the mechanisms and processes of stress tolerance can be accurately and comprehensively analyzed and evaluated. Also, by discovering new stress-resistant proteins, it is possible to improve stress resistance in transgenic plants with genetic engineering and genome editing methods and increase yield performance. The study of proteomics as a powerful tool for the separation and detection of stress-responsive proteins will help us in this way. Materials & Methods: This article is a review paper that was obtained by searching related articles on reliable sites. Research findings: Proteomics studies have led to the identification of several biological and physiological pathways responsible for tolerance to abiotic stresses in different plant species. In this regard, the identification of genes encoding the proteins involved in these processes as well as the transfer and overexpression of these candidate genes in plants is an effective strategy to improve stress resistance in economic agricultural products. In addition, the differential expression of genes in response to different stresses showed that some proteins have the same morphological and physiological manifestations in response to multiple stresses applied to them.
