Summary The fitness of host‐associated microbes depends on their ability to access nutrients in vivo . Identifying these mechanisms is significant for understanding how have evolved fill specific ecological niches within a host. Vibrio fischeri bioluminescent bacterium that colonizes and proliferates the light organ Hawaiian bobtail squid, which provides an opportunity study bacteria grow Here, transcription factor CysB shown be necessary V. both several sulfur sources vitro establish...
The symbioses that animals form with bacteria play important roles in health and disease, but the molecular details underlying how bacterial symbionts initially assemble within a host remain unclear.
In Bacillus subtilis, iron homeostasis is maintained by the ferric uptake regulator (Fur) and manganese relies on transport (MntR). Both Fur MntR function as bi-functional metalloregulators that repress import activate metal ion efflux systems. The ferrous ATPase, PfeT, derepressed hydrogen peroxide (H2O2) sensed PerR induced Fur. Mutants lacking PfeT are sensitive to intoxication. Here, we show mntR mutants also iron-sensitive, largely due decreased expression of MntR-activated MneP MneS...
The decision to pursue a science, technology, engineering, and/or math (STEM) career is often made in middle and high school, yet many students do not have access resources or opportunities navigate this path. Without guidance, obtaining job STEM may seem like daunting impossible task. Here, we present Write Researcher, program wherein school were paired with professionals at Cornell University as pen pals. Through personalized handwritten letters, her empowered advice, encouragement,...
