The use of root symbionts can enhance the establishment and survival of plant communities on drastically disturbed sites. Here, we are interested in root symbionts associated with plants from the Schefferville mining site in northern Quebec.

Collectively, our results demonstrate that the perception of symbionts by LysM-RLK is an ancestral feature in land plants, and suggest the existence of yet-uncharacterized AM fungi signals.

In these organs, both symbionts colonise similar intracellular niches, residing within membrane-bound, replicative vacuoles that occupy a substantial part of the cytoplasm of tick cells....Despite extensive genomic reduction, both symbionts have retained pathways for the biosynthesis of B vitamins and, in some cases, chorismate, a precursor used for the production of serotonin by ticks.

They exhibit remarkable diversity in their ecological roles, ranging from decomposers to mutualistic symbionts to parasites. They have a wide array of lifestyles, which reflect their diverse ecological roles and evolutionary adaptations to marine, aquatic, and terrestrial ecosystems.

Here, we propose that these microorganisms function as primary endophytic symbionts of plants, potentially protecting them from other endophytes.

To better understand their diversity and specialization, we cultured both of these Mesoplasma and Spiroplasma symbionts from the fungus-growing ant Trachymyrmex septentrionalis, providing the first isolated mollicutes from any fungus-growing ant species....This suggests that the T. septentrionalis symbionts comprise undescribed species that can exclude each other from a niche that is largely shared between them. Mesoplasma genomes and MAGs also demonstrate regional specificity with their T. septentrionalis ant hosts....Based on our genomic and phenotypic analyses, we describe these T. septentrionalis symbionts as Mesoplasma whartonense sp. nov. and Spiroplasma attinicola sp. nov., providing insight into their genomic and phenotypic diversity and cultures to facilitate future studies of how these common but poorly understood...Importance: Fungus-growing ants partner with multiple microbial symbionts to obtain food and remain free from disease. Of these symbionts, those inhabiting the ant gut remain the least understood and are known only from environmental surveys....Here, we describe the first cultures of the ant gut symbionts of the fungus-growing ant Trachymyrmex septentrionalis, using comparative genomics and phenotypic experiments to describe them as two novel species: Mesoplasma whartonense sp. nov. and Spiroplasma attinicola sp. nov.

Here, we uncover a metabolic arm in the control of symbionts by PRRs. We show that, in Drosophila, the PRRs PGRP-LC and PGRP-LE act independently of canonical NF-κB signaling to repress essential metabolic functions in the gut, such as digestion and central carbon metabolism.

Apicomplexans are wide-spread and diverse obligate symbionts of animals, and many-like the malaria-causing Plasmodium-are important human parasites.

These findings support the idea that while the microbiota of internal organs primarily supports digestive and immunological processes, the symbionts of external organs may play crucial roles in neutralizing toxic compounds from aquaculture practices, such as reduced nitrogen and sulfur compounds, and

To address this, we investigated the population dynamics of coral-dwelling gall crabs (Cryptochiridae), obligate symbionts of scleractinian corals, across four central Red Sea reefs.
