摘要

双球菌属包括杆状（Bacilli）和球形（Cocci）两种。在本研究中，我们旨在确定双球菌属的共同祖先是杆状还是球形。我们比较了各种Deinoccussecies和Thermus thermophilus中与细菌杆状相关的蛋白质同源物（MreB、MreC、MreD、MrdA、RodA和RodZ）。基于每种蛋白质和同源物的系统发育树反映了物种的进化关系，表明在双球菌进化过程中没有发生基因的水平转移。双球菌属的祖先是杆状的，当杆状形成系统在属内进化和多样化过程中消失时，出现了球形。

The Common Ancestor of Deinococcus Species was Rod-Shaped

The genusDeinococcusconsists of species in rod-shape (Bacilli) and spherical shape (Cocci).In this study, we aimed to determine whether the common ancestor ofDeinococcusspecies was rod-shaped or spherical.We compared the homologs of the proteins related to the rod-shape in bacteria (MreB, MreC, MreD, MrdA, RodA, and RodZ) in variousDeinococcusspecies andThermus thermophilus.The phylogenetic trees based on each protein and the homologs reflected the evolutionary relationships of the species, indicating that the Horizontal transfer of the genes did not occur during theDeinococcusevolution.The ancestor of the genusDeinococcuswas rod-shaped, and the spherical forms appeared when the rod-shaped formation system was lost during evolution and diversification within the genus.
