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

该项目的主要目标是提供热液条件对祖先新陈代谢的功能和进化的实验制约。我们将模拟早期地球热液条件，包括火山气体的存在，以识别现存的深分枝模式生物甲烷甲藻和氨热杆菌的转录本、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岩化地点收集的微生物群。这一结果将通过约束生命起源和演化的热液条件的控制参数，对CRC具有意义。

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.
