TLDR
Recent advances in the identification of upstream receptors/sensors and downstream MAPK substrates revealed the molecular mechanisms underlying MAPK functions in plant disease resistance and emerged as battlegrounds of plant-pathogen interactions.Abstract:
Mitogen-activated protein kinase (MAPK) cascades are highly conserved signaling modules downstream of receptors/sensors that transduce extracellular stimuli into intracellular responses in eukaryotes. Plant MAPK cascades play pivotal roles in signaling plant defense against pathogen attack. In this review, we summarize recent advances in the identification of upstream receptors/sensors and downstream MAPK substrates. These findings revealed the molecular mechanisms underlying MAPK functions in plant disease resistance. MAPK cascades have also emerged as battlegrounds of plant-pathogen interactions. Activation of MAPKs is one of the earliest signaling events after plant sensing of pathogen/microbe-associated molecular patterns (PAMPs/MAMPs) and pathogen effectors. MAPK cascades are involved in signaling multiple defense responses, including the biosynthesis/signaling of plant stress/defense hormones, reactive oxygen species (ROS) generation, stomatal closure, defense gene activation, phytoalexin biosynthes...read more

The Arabidopsis NPR1 Protein Is a Receptor for the Plant Defense Hormone Salicylic Acid
Yue Wu,Di Zhang,Jee Yan Chu,Patrick Boyle,Yong Wang,Ian D. Brindle,Vincenzo De Luca,Charles Després +7 more
TL;DR: It is demonstrated that NPR1 directly binds SA, but not inactive structural analogs, with an affinity similar to that of other hormone-receptor interactions and consistent with in vivo Arabidopsis SA concentrations.

A Renaissance of Elicitors: Perception of Microbe-Associated Molecular Patterns and Danger Signals by Pattern-Recognition Receptors
Thomas Boller,Georg Felix +1 more
TL;DR: Current evidence indicates that MAMPs, DAMPs, and effectors are all perceived as danger signals and induce a stereotypic defense response, and the importance of MAMP/PRR signaling for plant immunity is highlighted.
