Weevil Carbohydrate Intake Triggers Endosymbiont Proliferation: A Trade-Off between Host Benefit and Endosymbiont Burden

open access: yesmBio, 2023
Nutritional symbioses between insects and intracellular bacteria (endosymbionts) are a major force of adaptation, allowing animals to colonize nutrient-poor ecological niches. Many beetles feeding on tyrosine-poor substrates rely on a surplus of aromatic

Wolbachia Endosymbionts of Fleas Occur in All Females but Rarely in Males and Do Not Show Evidence of Obligatory Relationships, Fitness Effects, or Sex-Distorting Manipulations

open access: yesFrontiers in Microbiology, 2021
The widespread temporal and spatial persistence of endosymbionts in arthropod host populations, despite potential conflicts with their hosts and fluctuating environmental conditions, is puzzling.

Gut Microbiota Cannot Compensate the Impact of (quasi) Aposymbiosis in Blattella germanica

open access: yesBiology, 2021
Blattella germanica presents a very complex symbiotic system, involving the following two kinds of symbionts: the endosymbiont Blattabacterium and the gut microbiota.

The effects of temperature on prevalence of facultative insect heritable symbionts across spatial and seasonal scales

open access: yesFrontiers in Microbiology, 2023
Facultative inheritable endosymbionts are common and diverse in insects and are often found at intermediate frequencies in insect host populations. The literature assessing the relationship between environment and facultative endosymbiont frequency in ...

Unstable Relationship Between Braarudosphaera bigelowii (= Chrysochromulina parkeae) and Its Nitrogen-Fixing Endosymbiont

open access: yesFrontiers in Plant Science, 2021
Marine phytoplankton are major primary producers, and their growth is primarily limited by nitrogen in the oligotrophic ocean environment. The haptophyte Braarudosphaera bigelowii possesses a cyanobacterial endosymbiont (UCYN-A), which plays a major role

Pleiotropic impact of endosymbiont load and co-occurrence in the maize weevil Sitophilus zeamais. [PDF]

open access: yesPLoS ONE, 2014
Individual traits vary among and within populations, and the co-occurrence of different endosymbiont species within a host may take place under varying endosymbiont loads in each individual host. This makes the recognition of the potential impact of such

Effects of 16S rDNA sampling on estimates of the number of endosymbiont lineages in sucking lice [PDF]

open access: yesPeerJ, 2016
Phylogenetic trees can reveal the origins of endosymbiotic lineages of bacteria and detect patterns of co-evolution with their hosts. Although taxon sampling can greatly affect phylogenetic and co-evolutionary inference, most hypotheses of endosymbiont ...

Evidence of phylosymbiosis in Formica ants

open access: yesFrontiers in Microbiology, 2023
IntroductionInsects share intimate relationships with microbes that play important roles in their biology. Yet our understanding of how host-bound microbial communities assemble and perpetuate over evolutionary time is limited.

Co-Occurrence of Viruses, Plant Pathogens, and Symbionts in an Underexplored Hemipteran Clade

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Interactions between insect symbionts and plant pathogens are dynamic and complex, sometimes involving direct antagonism or synergy and sometimes involving ecological and evolutionary leaps, as insect symbionts transmit through plant tissues or plant ...

Discovery of Early-Branching Wolbachia Reveals Functional Enrichment on Horizontally Transferred Genes

open access: yesFrontiers in Microbiology, 2022
Wolbachia is a widespread endosymbiont of insects and filarial nematodes that profoundly influences host biology. Wolbachia has also been reported in rhizosphere hosts, where its diversity and function remain poorly characterized.
