Diversity and Transmission of Gut Bacteria in Atta and Acromyrmex Leaf-Cutting Ants during Development

Frontiers in Microbiology, 2017
The social Hymenoptera have distinct larval and adult stages separated by metamorphosis, which implies striking remodeling of external and internal body structures during the pupal stage.

Varied effects of algal symbionts on transcription factor NF-κB in a sea anemone and a coral: possible roles in symbiosis and thermotolerance [PDF]

, 2019
Many cnidarians, including the reef-building corals, undergo symbiotic mutualisms with photosynthetic dinoflagellate algae of the family Symbiodiniaceae.

Construction of an O2‐responsive engineering bioreactor for enhanced indole‐3‐propionic acid production and deoxynivalenol detoxification

Responsive Materials, EarlyView.
An oxygen‐responsive living bioreactor was engineered via interspecies protoplast fusion, converting oxygen from an inhibitory stress into a programmable signal for sustained indole‐3‐propionic acid (IPA) production. This genetically encoded bioreactor enables robust aerobic operation and therapeutic efficacy of deoxynivalenol detoxification in vivo ...

Ontogenetic changes in the bacterial symbiont community of the tropical demosponge Amphimedon queenslandica: metamorphosis is a new beginning

Frontiers in Marine Science, 2016
Vertical transmission of bacterial symbionts, which is known in many species of sponge (Porifera), is expected to promote strong fidelity between the partners.

Evolution of host support for two ancient bacterial symbionts with differentially degraded genomes in a leafhopper host. [PDF]

, 2018
Plant sap-feeding insects (Hemiptera) rely on bacterial symbionts for nutrition absent in their diets. These bacteria experience extreme genome reduction and require genetic resources from their hosts, particularly for basic cellular processes other than

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Transcriptomic responses of the olive fruit fly Bactrocera oleae and its symbiont Candidatus Erwinia dacicola to olive feeding [PDF]

, 2017
The olive fruit fly, Bactrocera oleae, is the most destructive pest of olive orchards worldwide. The monophagous larva has the unique capability of feeding on olive mesocarp, coping with high levels of phenolic compounds and utilizing non-hydrolyzed ...

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

Insect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Functional stability of Spirochaetota symbionts in the precious octocoral Corallium rubrum under heat stress

Environmental Microbiome
Background Octocoral gorgonians are the engineer species of the Mediterranean coralligenous assemblages, but they are threatened with collapse due to recurring marine heat waves.

The Evolution of Diversity [PDF]

, 2017
Since the beginning of time, the pre-biological and the biological world have seen a steady increase in complexity of form and function based on a process of combination and re-combination.
