The Effect of Outer Space and Other Environmental Cues on Bacterial Conjugation by Bar Piscon, Eliana Pia Esposito, Boris Fichtman, Guy Samburski, Lihi Efremushkin, Shimon Amselem, Amnon Harel, Galia Rahav, Raffaele Zarrilli, Ohad Gal-Mor

“…ABSTRACT Bacterial conjugation is one of the most abundant horizontal gene transfer (HGT) mechanisms, playing a fundamental role in prokaryote evolution. A better understanding of bacterial conjugation and its cross talk with the environment is needed for a more complete understanding of HGT mechanisms and to fight the dissemination of malicious genes between bacteria. …”

FurC (PerR) contributes to the regulation of peptidoglycan remodeling and intercellular molecular transfer in the cyanobacterium Anabaena sp. strain PCC 7120 by Cristina Sarasa-Buisan, Mercedes Nieves-Morión, Sergio Arévalo, Richard F. Helm, Emma Sevilla, Ignacio Luque, María F. Fillat

“…Assessment of the exometabolome from both strains revealed the release of two peptidoglycan fragments in furC-overexpressing cells, namely 1,6-anhydro-N-acetyl-β-D-muramic acid (anhydroMurNAc) and its associated disaccharide (β-D-GlcNAc-(1-4)-anhydroMurNAc), suggesting alterations in peptidoglycan breakdown and recycling.IMPORTANCECyanobacteria are ubiquitous photosynthetic prokaryotes that can adapt to environmental stresses by modulating their extracellular contents. …”
