Tracing primordial metabolism reflected by microorganisms under hydrothermal conditions (P13+)

本项目的主要目的是提供热液条件对祖先代谢功能和进化的实验约束。我们将模拟早期地球热液条件，包括火山气体的存在，以识别现存深分支模式生物Methanopyrus kandleri和Thermovibrio amificans的转录本、代谢物和碳途径中的祖先指纹。这项研究还将包括从两个蛇纹石化地点收集的微生物群。研究结果对限定热液条件对生命起源和演化的控制参数具有重要意义。

The main goal of this project is to provide experimental constraints of hydrothermal conditions on the functioning and evolution of ancestral metabolism. We will simulate early earth hydrothermal conditions including the presence of volcanic gases to identify ancestral fingerprints in the transcripts, metabolites and carbon pathways of the extant deeply branching model organisms, Methanopyrus kandleri and Thermovibrio ammonificans. The study will also include microbiota collected from two serpentinization sites. The results will have meaning for the CRC by constraining the controlling parameters of hydrothermal conditions for the origin and evolution of life.
