The phytohormone salicylic acid (SA) is best known as a mediator of host defense response and systemic acquired resistance. However, it can also inhibit growth. In this dual capacity it coordinates developmental and environmental inputs to allocate resources to growth or defense. We have employed genetic screens, mechanistic biochemistry, and temporally and spatially resolved transcriptional analysis to identify and elucidate key components and nodes of SA metabolism and response. Together, these findings illustrate how the concentration of SA, in developmental context, drives functional outcomes.
