NDL India: Thermophiles Biodiversity, Ecology, and Evolution
Skickas inom vardagar. These are indeed exciting times to be a microbiologist. Microbes can thrive in almost any environment where there is an exploitable energy source, and, as a result, the possible existence of microbial life elsewhere in the solar system has stimulated the imaginations of many.
Extremophiles have taken center stage in these investigations, and thermophiles have taken on the lead roles. In one of our study on two circumneutral hot springs in Tengchong geothermal region involving integrated comparative genomics, we obtained six Aigarchaeota metagenomic bins which could be used to address the gaps in understanding the origin and evolutionary history of the Aigarchaeota and their roles in biogeochemical cycling.
Our analysis revealed a facultative or strictly anaerobic lifestyle of Aigarchaeota with an ability to oxidize sulfide to gain energy for growth Figure 2. Evolutionary genomic analyses of Thaumarchaeota and Aigarchaeota suggested that both the phyla evolved from hot habitats and they shared a large proportion of gene families with their last common ancestor. Adaptation to a different habitat led to the functional differentiation of Aigarchaeota from Thaumarchaeota, with the latter invading a wide diversity of non-thermal environments Figure 3.
Genomic inference of the metabolism and evolution of the archaeal phylum Aigarchaeota
Genes acquired horizontally from Euryarchaeota and Firmicutes played a significant role in the functional diversification of Aigarchaeota in hot spring habitats. This study represented a significant advancement in our understanding of the genomic diversity and evolution of Aigarchaeota. This work also highlights the extraordinary diversity of microbial life still awaiting discovery in terrestrial geothermal systems.
