Population structure and divergence in the Roseobacter group - implications for the ecology and evolution (A07)

该项目将阐明玫瑰杆菌组系统发育相关细菌支系内不同的基因组和生态生理学特征，并确定正在进行的物种形成过程的进化驱动因素。我们将重点关注在前一个资助阶段确定的三个具有凝聚力的棕杆菌属种群，并进行比较基因组和生态生理学分析。将硫杆菌和RCA簇纳入我们的比较种群基因组分析将揭示驱动不同罗斯杆菌亚群分化和适应过程的不同进化机制。

This project will elucidate the genomic and ecophysiological traits which vary within clades of phylogenetically related bacteria of the Roseobacter group and determine the evolutionary drivers of the ongoing speciation process. We will focus on three cohesive populations of the genus Phaeobacter identified in the previous funding phase and conduct a comparative genomic and ecophysiological analysis. Including Sulfitobacter and the RCA cluster in our comparative population genomic analysis will reveal the distinct evolutionary mechanisms that drive the divergence and adaptation processes in different Roseobacter subgroups.
