Diversity of Archaea II

32
Archaea, one of the three domains of life, exhibit remarkable diversity and adaptability, thriving in both extreme and moderate environments. Historically, most identified archaea have been classified into two major phyla: Euryarchaeota and Crenarchaeota. However, recent molecular studies have expanded this classification to include three additional phyla: Thaumarchaeota, Nanoarchaeota, and Korarchaeota, each exhibiting unique characteristics and ecological roles.Thaumarchaeota: Mesophiles...

Hyperthermophilic archaea are a group of extremophiles thriving at temperatures above 80°C, often in hydrothermal vents and volcanic soils where conditions surpass the boiling point of water. At such temperatures, proteins, membranes, and DNA in most organisms degrade, but hyperthermophiles have evolved remarkable adaptations to maintain stability and function.Unique Cellular FeaturesHyperthermophilic membranes are composed of a monolayer of biphytanyl tetraether lipids, which resist...

Crenarchaeota, a prominent phylum of Archaea, is remarkable for its ability to thrive in extreme environments characterized by high temperatures and acidity. These microorganisms inhabit sulfuric hot springs, volcanic systems, and submarine hydrothermal vents, where temperatures often exceed 100°C. The unique adaptations of Crenarchaeota not only allow survival under such extreme conditions but also provide insights into the mechanisms of life in primordial Earth-like...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Area of Science:

  • Evolutionary Biology
  • Microbial Ecology
  • Genomics

Background:

  • Host-microbe interactions can lead to parallel evolutionary diversification (co-diversification).
  • Previous co-diversification tests were limited to simple, binary host-symbiont systems.
  • Complex host-associated microbiota present challenges for assessing co-diversification.

Purpose of the Study:

  • To review evidence for co-diversification in complex microbiota.
  • To outline a hypothesis testing approach for multipartite symbiosis.
  • To advocate for microbiota-wide scans to identify co-diversifying symbiont lineages.

Main Methods:

  • Extending co-diversification tests to entire microbial phylogenies (e.g., metagenome-assembled genomes, amplicon sequence variants).
  • Utilizing microbiota-wide scans to identify co-diversifying symbionts within host clades.
  • Employing multi-level permutation tests to account for phylogenetic non-independence and multiple comparisons.

Main Results:

  • Developed and discussed tools for microbiota-wide co-diversification analysis.
  • Demonstrated how to identify co-diversifying symbionts in complex microbial communities.
  • Relative ages of symbiont clades can corroborate co-diversification findings.

Conclusions:

  • Co-diversification tests can be successfully extended to complex microbiota.
  • Microbiota-wide scans offer a powerful approach to discover ancient symbiotic lineages.
  • This framework enables interrogation of molecular evolution and lineage turnover in host-associated symbionts.
