DOI: 10.1007/s00248-019-01417-4
Abstract: Facultative, intracellular bacterial symbionts of arthropods may dramatically affect host biology and reproduction. The length of these symbiont-host associations may be thousands to millions of years, and while symbiont loss is predicted, there have been… read more here.

DOI: 10.1007/s00284-018-1493-1
Abstract: Caedibacter taeniospiralis is an obligate bacterial symbiont living in the cytoplasm of the ciliate Paramecium tetraurelia. Different studies analyzing the effect of this symbiont on its host’s growth and maximal cell density arrive at contradicting… read more here.

DOI: 10.1007/s00338-021-02116-8
Abstract: Coral reef ecosystems are under threat from the frequent and severe impacts of anthropogenic climate change, particularly rising sea surface temperatures. The effects of thermal stress may be ameliorated by adaptation and/or acclimation of the… read more here.

DOI: 10.1038/srep42206
Abstract: Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a major rice pest that harbors an endosymbiont ascomycete fungus, Entomomyces delphacidicola str. NLU (also known as yeast-like symbiont, YLS). Driving by demand of novel population management tactics (e.g.… read more here.

DOI: 10.1073/pnas.2205856119
Abstract: Protists are important regulators of microbial communities and key components in food webs with impact on nutrient cycling and ecosystem functioning. In turn, their activity is shaped by diverse intracellular parasites, including bacterial symbionts and… read more here.

Unravelling the relationship between the tsetse fly and its obligate symbiont Wigglesworthia: transcriptomic and metabolomic landscapes reveal highly integrated physiological networks
Sign Up to like & getrecommendations! Published in 2017 at "Proceedings of the Royal Society B: Biological Sciences"
DOI: 10.1098/rspb.2017.0360
Abstract: Insects with restricted diets rely on obligate microbes to fulfil nutritional requirements essential for biological function. Tsetse flies, vectors of African trypanosome parasites, feed exclusively on vertebrate blood and harbour the obligate endosymbiont Wigglesworthia glossinidia.… read more here.

Genetic manipulation allows in vivo tracking of the life cycle of the son‐killer symbiont, Arsenophonus nasoniae, and reveals patterns of host invasion, tropism and pathology

DOI: 10.1111/1462-2920.14724
Abstract: Summary Maternally heritable symbionts are common in arthropods and represent important partners and antagonists. A major impediment to understanding the mechanistic basis of these symbioses has been lack of genetic manipulation tools, for instance, those… read more here.

DOI: 10.1111/1462-2920.16310
Abstract: Vertical transmission of symbionts in insects is critical to persistence of symbioses across host generations. The key time point and related cellular/molecular mechanisms underlying the transmission in most insects remain unclear. Here, we reveal that… read more here.

DOI: 10.1111/mec.16190
Abstract: As sea surface temperatures increase, many coral species that used to harbor symbionts of the genus Cladocopium have become colonized with the thermally tolerant genus, Durusdinium. Here, we asked how gene expression in the symbionts… read more here.
