TL;DR: Intensive mutational processes can account for virtually all of the observed genetic polymorphism, with no demonstrable contribution from horizontal gene transfer (HGT), and no evidence that environmental strains have played a role in the evolution of the outbreak strain.

TL;DR: It is demonstrated that comEA transcription and the horizontal acquisition of DNA by V. cholerae are induced in response to purified CAI-1 and AI-2, and also by autoinducers derived from other Vibrios co-cultured with V. Cholerae within a mixed-species biofilm, suggesting that autoinducer communication within a consortium may promote DNA exchange among VibRIos.

TL;DR: The results support a speculative model that when V. cholerae reaches high density on chitin, CytR–CRP interactions ‘anti‐activate’ multiple genes, including a possible factor that negatively controls DNA uptake, and a nucleoside scavenging mechanism couples nutrient stress and cell–cell signalling to natural transformation in V.

TL;DR: Strain PsJN appears highly efficacious for the control of Pierce's disease when used as an eradicant treatment that can be easily made even by spray application.

TL;DR: This work characterize another such factor encoded by PD0956, designated as an antivirulence secreted protease “PrtA” that displays a central role in controlling in vitro cell proliferation, length, motility, biofilm formation, and in planta virulence.
