Summary
Archaea, though rare in eukaryotes, significantly impact plant health. This review highlights their role in plant growth, stress adaptation, and immunity activation through root colonization and volatile emissions.
Area of Science:
- Microbiology
- Plant Science
- Ecology
Background:
- Archaea are abundant in extreme environments but less studied in eukaryotic hosts.
- They are a significant component of plant-associated microbiomes (phytobiomes).
- Limited research exists on archaea's role in plant health and symbiosis.
Purpose of the Study:
- To review recent advancements in understanding archaea's contribution to plant traits.
- To synthesize functional and molecular data on archaea in plant interactions.
- To explore archaea's role in plant growth, stress adaptation, and immunity.
Main Methods:
- Literature review of recent functional and molecular data.
- Synthesis of studies on root colonization by archaea.
- Analysis of volatile emissions from archaea and their effect on plant immunity.
Main Results:
- Archaea influence plant growth and adaptation to abiotic stresses.
- Root colonization by archaea is a key interaction mechanism.
- Volatile emissions from archaea can activate plant systemic immunity.
Conclusions:
- Archaea play a substantial role in plant health and phytobiome interactions.
- Understanding archaea-plant symbiosis offers new insights into plant resilience.
- These findings represent a paradigm shift in plant-microbiota interaction research.

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...

Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
46.1K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

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...
