In this Review, we provide an overview of the currently recognized
archaeal diversity, summarize new findings on the metabolic potential of recently described archaeal lineages, and discuss these data in light of archaeal evolution.
On the basis of our current understanding, much
archaeal diversity still defies genomic exploration.
Not exact matches
Recently discovered
archaeal lineages include mesophiles and (hyper --RRB- thermophiles, anaerobes and aerobes, autotrophs and heterotrophs, a large
diversity of putative
archaeal symbionts, as well as previously unknown acetogens and different groups of methanogens (see the figure).
Spang et al. review the
diversity of Archaea and their genomes, metabolomes, and history, which clarifies the biology and placement of recently discovered
archaeal lineages.
Efforts to obtain and study genomes and enrichment cultures of uncultivated microbial lineages will likely further expand our knowledge about
archaeal phylogenetic and metabolic
diversity and their cell biology and ecological function.
