The Plant Pathogen Xanthomonas campestris pv. campestris Exploits N-Acetylglucosamine during Infection

mBio, 2014
N-Acetylglucosamine (GlcNAc), the main component of chitin and a major constituent of bacterial peptidoglycan, is present only in trace amounts in plants, in contrast to the huge amount of various sugars that compose the polysaccharides of the plant cell

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, Volume 293, Issue 9, Page 2772-2793, May 2026.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Climate Change Projected to Double the Richness and Abundance of Soilborne Phytopathogenic Fungi in Southern Maritime Antarctica

Global Change Biology, Volume 32, Issue 5, May 2026.
We sequenced fungal DNA in barren soils sampled from 12 sites along a 1900‐km transect through sub‐ and Maritime Antarctica and Patagonia. Using LASSO regression, we found air temperature ‐ and notably mean annual air temperature (BIO1) ‐ to be a highly significant predictor for the richness and relative abundance of soilborne plant pathogens.

A secreted metal-binding protein protects necrotrophic phytopathogens from reactive oxygen species

Nature Communications, 2019
The authors identify a family of iron-binding proteins that is present in phytopathogenic bacteria, fungi and oomycetes. Some of these proteins are secreted, bind metals, protect the pathogen from H2O2-induced death, and are involved in plant infection.
