Structural basis for transcription initiation by bacterial ECF σ factors

Nature Communications, 2019
Extra-cytoplasmic function (ECF) σ factors allow bacteria to rapidly respond to stress conditions. Here the authors provide insights into the mechanism of bacterial stress-induced transcription by determining the crystal structures of the M. tuberculosis

Quorum-Sensing Systems in the Plant Growth-Promoting Bacterium Paraburkholderia phytofirmans PsJN Exhibit Cross-Regulation and Are Involved in Biofilm Formation

Molecular Plant-Microbe Interactions, 2017
Quorum-sensing systems play important roles in host colonization and host establishment of Burkholderiales species. Beneficial Paraburkholderia species share a conserved quorum-sensing (QS) system, designated BraI/R, that controls different phenotypes ...

Alpha-ketoglutarate protects Streptomyces coelicolor from visible light-induced phototoxicity

Biochemistry and Biophysics Reports, 2017
It has been known that some Streptomyces species, including the model strain Streptomyces coelicolor, are vulnerable to visible light. Much evidence demonstrated that the phototoxicity induced by visible light is a consequence of the formation of ...

Marine synthetic ecology: From microbial communities to ecosystems

iScience
Marine ecosystems are vital for global ecological functions and human health but face escalating threats from both anthropogenic activities and global climate change. Marine microorganisms, comprising over two-thirds of the marine biomass, play essential roles in biogeochemical cycling of elements and food webs.
