AI Article Synopsis
- Salicylic acid (SA) is a critical plant hormone that triggers defense mechanisms during pathogen infections, but the details of its biosynthesis remain unclear.
- Two main pathways for SA production exist, the ICS and PAL pathways, which both originate from chorismate, but the significance of each varies among different plant species.
- This review focuses on the mechanisms behind SA synthesis and highlights the need to understand these pathways to enhance our knowledge of plant responses to pathogens and how these responses can be disrupted.
Article Abstract
Salicylic acid (SA) is an important plant hormone that is best known for mediating host responses upon pathogen infection. Its role in plant defense activation is well established, but its biosynthesis in plants is not fully understood. SA is considered to be derived from two possible pathways; the ICS and PAL pathway, both starting from chorismate. The importance of both pathways for biosynthesis differs between plant species, rendering it hard to make generalizations about SA production that cover the entire plant kingdom. Yet, understanding SA biosynthesis is important to gain insight into how plant pathogen responses function and how pathogens can interfere with them. In this review, we have taken a closer look at how SA is synthesized and the importance of both biosynthesis pathways in different plant species.
