The genetic exchange between populations is a prerequisite for the long-term evolution of bacteria, however its short-term dynamics are largely unexplored. This project aims to define the temporal dynamics of gene transfer and how it shapes the genetic composition of entire bacterial communities. Using innovative DNA sequencing technologies and bioinformatics, This project aims to offer a significant new understanding of the short-term diversification of communities and how different evolutionary forces shape bacterial function. It will show how bacterial systems can adapt to new environmental conditions and the effect on essential ecosystem functions.

种群之间的基因交换是细菌长期进化的先决条件，但其短期动态在很大程度上尚未被探索。该项目旨在定义基因转移的时间动态，以及它如何塑造整个细菌群落的遗传组成。利用创新的DNA测序技术和生物信息学，该项目旨在为群落的短期多样化以及不同的进化力量如何塑造细菌功能提供重要的新理解。它将展示细菌系统如何适应新的环境条件以及对基本生态系统功能的影响。
