Prigozhin and Krasileva identify highly variable NLR subfamilies responsible for the generation of new immune receptor specificities. The Plant Cell (2021)   By Daniil M. Prigozhin1 and Ksenia V. Krasileva2 1Lawrence Berkeley National Laboratory 2University of California Berkeley  Background:…

Plant cells sense endogenous and exogenous molecules through proteins localized to the cell surface. While numerous ligands that mediate a variety of developmental and stress processes are known, cognate receptors for many ligands remain unidentified. Rhodes and colleagues have now shown the Arabidopsis…

Mitogen-activated protein kinases (MAPKs) are conserved protein kinases in eukaryotes that participate in signaling from cytoplasmic to chromatin events to allow transcription reprogramming. MAPKs play prominent roles at the chromatin level. Rayapuram et al. report a chromatin-associated phosphoproteome…

The exocyst is a conserved protein complex that mediates tethering of secretory vesicle to the plasma membrane prior to SNARE-mediated membrane fusion. Exo70 is one of eight subunits and has expanded into 23 homologs in Arabidopsis. Brillada and Teh et al. identified Exo70B2 as a bona fide exocyst subunit…
