Review: The long road to engineering durable disease resistance in wheat (Curr. Opin. Biotechnol.)

This review by Wulff and Krattinger is a beautifully written “must read”. As the title suggests, it takes the reader on a journey of scientific progress, starting from the “first controlled cross between two wheat species” to the present, with a look into the future. Triticum aestivum (bread…

The secret arsenal of phytopathogenic fungi

Martínez-Cruz et al. identify fungal effectors with chitinase activity, which suppress chitin-triggered immunity. by Jesús Martínez-Cruza,b, Diego Romeroa,b, Jesús Hierrezueloa,b, Michael Thonc, Antonio de Vicentea,b and Alejandro Pérez-Garcíaa,b aDepartamento de Microbiología, Facultad…

Highly Diverse Plant Immune Receptors Form a Species-wide Reservoir of New Recognition Specificities

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:…

When fungi get ‘SCOOP’ed: MIK2 receptor kinase perceives SCOOP phytocytokines in Arabidopsis thaliana (Nature Comms)

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…

Chromatin phosphoproteomics identifies an AT-hook motif protein involved in PAMP-triggered immunity (PNAS)

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…

Exo70B2 functions as a exocyst subunit in secretion linked to immunity and autophagy (Plant Cell)

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…

The Complex Process of Plant Innate Immunity

Liu et al. demonstrate that EIJ1 acts as a key repressor of plant immunity. Plant Cell. https://bit.ly/37MF1tg By Hailun Liu, Yuge Li and Xingliang Hou, South China Botanical Garden, Chinese Academy of Sciences Background: Plants have evolved a complicated network to modulate the immune response.…
