报告简介:Transformation inStreptococcus pneumoniaeprovided the earliest evidence that genes consist of DNA. It has since become a powerful tool for direct manipulation of the pneumococcal genome, accelerating study of this widespread devastating human pathogen. Recent advances in its study reveal that uptake of naked DNA in the laboratory represents but one step in a highly orchestrated mechanism by which one cell lyses another, obtaining access to DNA of different ancestry. Operation of this mechanism during mixed infections in natural hosts gives each strain ready access to the large pneumococcal pan-genome, as well as new genes from other related species.
