Review: Regulation of pattern recognition receptor signalling by phosphorylation and ubiquitination (Curr. Opin. Plant Biol.)

A key step in pathogen recognition occurs at the cell surface with the interaction between receptor-like kinases (pattern-recognition receptors) and their ligands. This event triggers a signal-transduction cascade that leads to the induction of defense responses. Mithoe and Menke review our current understanding of these signals, focusing on the contributions of protein activation and inactivation by phosphorylation and ubiquitination, largely uncovered through proteomics methods, and drawing on both rice and Arabidopsis models.
