摘　　要：Land plants use diverse hormones to coordinate their growth,development and responses against biotic and abiotic stresses.Salicylic acid(SA)is an essential hormone in plant immunity,with its levels and signaling tightly regulated to ensure a balanced immune output.Over the past three decades,molecular genetic analyses performed primarily in Arabidopsis have elucidated the biosynthesis and signal transduction pathways of key plant hormones,including abscisic acid,jasmonic acid,ethylene,auxin,cytokinin,brassinosteroids,and gibberellin.Crosstalk between different hormones has become a major focus in plant biology with the goal of obtaining a full picture of the plant hormone signaling network.This review highlights the roles of SA in plant immunity and summarizes our current understanding of the pairwise interactions of SA with other major plant hormones.The complexity of these interactions is discussed,with the hope of stimulating research to address existing knowledge gaps in hormone crosstalk,particularly in the context of balancing plant growth and defense.
