Abstract

Salicylic acid (SA) signaling has been associated with phospholipids and the enzymes that metabolize them. However, despite studies conducted by other research groups, the role of SA signaling via phospholipids in plant responses to phytoregulators is not yet fully understood. The signal transduction pathway involves the generation of secondary messengers, through the enzymes such as phospholipase C (PLC) and phospholipase D (PLD). The signaling pathway of SA was evaluated in different models of plants, where it was observed that this compound regulates enzymatic activities to generate a rapid cellular response. In this chapter, we review the important aspects of the relationship of the SA effects with phospholipid signal transduction and cellular responses to this component.
