A multitude of biotic and abiotic stress factors do harm to plants by bringing about diseases
and inhibiting normal growth and development. As a pivotal signaling molecule, salicylic
acid (SA) plays crucial roles in plant tolerance responses to both biotic and abiotic stresses,
thereby maintaining plant normal growth and improving yields under stress. In view of this,
this paper mainly discusses the role of SA in both biotic and abiotic stresses of plants. SA
regulates the expression of genes involved in defense signaling pathways, thus enhancing …
