The plant hormone salicylic acid (SA) plays an essential role in the regulation of diverse biological processes throughout the entire lifespan of the plant. SA first emerged as an endogenous signal capable of inducing plant defence responses both at the site of infection and in the systemic tissue of the plant. For more than 200 years, the plant hormone salicylic acid (SA) has been studied for its medicinal use in humans. In contrast, evident during the past 20 years has shown its extensive signaling role in plants particularly in defense against pathogens. The activation of Systemic Acquired Resistance (SAR) is associated with the discriminating level of expression of the pathogenesis-related proteins, which possess antimicrobial activity. We discuss the progress made in understanding SA biosynthesis and signaling, its relationship with other mechanisms in plant defense and the practical utility in targeting this defense mechanism for enhancing disease resistance in cotton.
