Pseudomonas aeruginosa PA14 produces R-bodies, extendable protein polymers with roles in host colonization and virulence

Abstract

R-bodies are long, extendable protein polymers formed in the cytoplasm of some bacteria. Here, Wang et al. show that Pseudomonas aeruginosa produces R-bodies during colonization of plant and nematode hosts, and R-bodies induce ribosome cleavage and translational inhibition in nematodes.
