Salicylic Acid Steers the Growth-Immunity Tradeof

Journal: Trends in Plant Science       Impact factor: 14.416 Published date: June, 2020       Published by: Utrecht University, The Netherlands

Research Content

Plants possess an effective immune system to combat most microbial attackers. The activation of immune responses to biotrophic pathogens requires the hormone salicylic acid (SA). Accumulation of SA triggers a plethora of immune responses (like massive transcriptional reprogramming, cell wall strengthening, and production of secondary metabolites and antimicrobial proteins). A tradeoff of strong immune responses is the active suppression of plant growth and development. The tradeoff also works the opposite way, where active growth and developmental processes suppress SA production and immune responses.

Research Result

We review research on the role of SA in the growth-immunity tradeoff,which is instrumental in resistance breeding of crops with optimal growth and effective immunity.

The phytohormone salicylic acid (SA) stimulates plant immune responses to a broad range of plant pathogens.SA-induced immune responses contribute to the growth–immunity tradeoff: immune responses actively suppress growth and development and also the other way around, growth and developmental processes can suppress immunity.Immune signaling and growth-related processes directly affect SA biosynthesis and metabolism.
