Current Knowledge on the Role of Salicylic Acid for Stress Tolerance on Field Crops

Abstract

Salicylic acid is a well-known signal molecule that mediates plant resistance and is also involved in the control of plant development. Conversely, despite its well-established role in plant resistance, its impact on plant development is still poorly understood. the body of research indicating the essential functions of salicylic acid in controlling cell division and expansion, two processes that ultimately determine a plant's structure. This study summarizes the current knowledge of the mechanisms and molecular mechanisms via which salicylic acid regulates plant development through a range of pathways. Here, the role of salicylic acid in controlling growth regulation through effects on cell division and expansion is highlighted. The methods and molecular  processes by which salicylic acid controls stress tolerance through a variety of pathways are compiled in this study. The relationships between salicylic acid and other hormones as well as their significance in determining plant development were also covered. Future crop improvement will greatly benefit from a deeper understanding of the process underpinning salicylic acid-mediated growth.
