对植物激素水杨酸的研究与探索

Plant hormone Salicylic acid (SA) is a key signal molecule, which plays an important role in plant immune process. Since the accumulation of SA can affect the normal growth and development of plants and lead to the reduction of plant resistance, the biosynthesis and signaling processes of SA are strictly regulated. With the deepening of research, people have a deeper understanding of the SA signaling pathway, such as NPRs, TGAs and other signal components and their functions have been discovered. This review will introduce the research progress of SA from the aspects of SA biosynthesis pathways and signal transduction components, so as to provide a reference for further study of SA.
