Research Article | SpotlightAgrobacterium tumefaciens Deploys a Versatile Antibacterial Strategy To Increase Its Competitiveness...The T6SS encodes multiple effectors with diverse functions, but little is known about the biological significance of harboring such a repertoire of effectors. We reported that the T6SS antibacterial activity of the plant pathogen Agrobacterium tumefaciens can be enhanced under carbon starvation or when recipient cell wall peptidoglycan is disturbed.
Research ArticleDouble Tubular Contractile Structure of the Type VI Secretion System Displays Striking Flexibility and ElasticityThe cell wall is a physical scaffold that all transenvelope complexes have to cross for assembly. However, the cell wall-deficient state has been described as a common condition found in both Gram-negative and Gram-positive pathogens during persistent infections. Loss of cell wall is known to have pleiotropic physiological effects, but how membrane-anchored large cellular organelles adapt to this unique state is less completely...
