Transcriptional Coactivator: Driving Force of Plant Immunity and Coordinator of Plant Growth and Defense

Abstract:

The plant hormone salicylic acid (SA) plays a vital role in defense against biotrophic and hemi-biotrophic pathogens. NPR1, as the master regulator of SA signaling and a receptor of SA, controls the expression of 98% of around 2800 SA-regulated genes. On the other hand, EDS1 has been shown to be essential for PAMP-triggered immunity, effector-triggered immunity, pathogen-induced SA accumulation, plant defense gene expression, and systemic acquired resistance. Early studies showed that EDS1 shares sequence homology and structural similarity to lipases. However, subsequent biochemical studies found no lipase activity in EDS1 protein. Despite its importance in almost every aspect of plant immunity, the molecular function of EDS1 remained elusive for more than twenty years. In my presentation, I will focus on two projects related to NPR1 and EDS1. First, I will show you how two interacting transcriptional coactivators cooperatively promote plant defense responses. In the second part of my talk, I will tell you a story on how plants coordinate growth and defense through key players in SA and brassinosteroid signaling pathways.公告
