摘要: Background Horizontal gene transfer (HGT) is considered to be a major force driving the evolutionary history of prokaryotes. HGT widespread in prokaryotes, contributing genomic repertoire prokaryotic organisms, and particularly apparent Rickettsiales genomes. Gene gains from both distantly closely related organisms play crucial roles evolution bacterial In this work, we focus on genes transferred species into species.
