The adaptive oxidative stress response allows bacteria to adapt to hostile environmental conditions. We explored how the evolution of cellular ROS in oxidative stress triggers physiological and genetic changes in multiple pathogenic species. Our study posits that growth-survival tradeoffs under oxidative stress enact a diverse array of genetic and physiological changes resulting in cross-resistance to acid, antimicrobial resistance, and metabolic reprogramming in bacteria.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
