Cascading effects of defensive endosymbionts [PDF]

Current Opinion in Insect Science, 2019
Defensive endosymbionts are now understood to be widespread among insects, targeting many different threats, including predators, parasites and disease. The effects on natural enemies can be significant, resulting in dramatic changes in the outcome of interactions between insects and their attackers.

From insect endosymbiont to phloem colonizer: comparative genomics unveils the lifestyle transition of phytopathogenic Arsenophonus strains

mSystems
Bacteria infecting the plant phloem represent a growing threat worldwide. While these organisms often resist in vitro culture, they multiply both in plant sieve elements and hemipteran vectors.

High prevalence and lack of diversity of Wolbachia pipientis in Aedes albopictus populations from Northeast Brazil

Memorias do Instituto Oswaldo Cruz, 2011
The use of Wolbachia as a tool to control insect vectors has recently been suggested. In this context, studies on the prevalence and diversity of this bacterium in wild populations are relevant.

Endosymbiotic Fungal Diversity and Dynamics of the Brown Planthopper across Developmental Stages, Tissues, and Sexes Revealed Using Circular Consensus Sequencing

Insects
Endosymbiotic fungi play an important role in the growth and development of insects. Understanding the endosymbiont communities hosted by the brown planthopper (BPH; Nilaparvata lugens Stål), the most destructive pest in rice, is a prerequisite for ...

The Effect of Density-Dependent Phase on the Locust Gut Bacterial Composition

Frontiers in Microbiology, 2019
The desert locust demonstrates density-dependent phase polyphenism: For extended periods it appears in a non-aggregating, non-migrating phenotype, known as the solitary phase. When circumstances change, solitary individuals may aggregate and transform to

Comparative Endosymbiont Community Structures of Nonviruliferous and Rice Stripe Virus-Viruliferous Laodelphax striatellus (Hemiptera: Delphacidae) in Korea

Viruses
Insects and their bacterial endosymbionts form intricate ecological relationships, yet their role in host–pathogen interactions are not fully elucidated.

Divide and shape: an endosymbiont in action [PDF]

Planta, 2012
The endosymbiotic evolution of the plastid within the host cell required development of a mechanism for efficient division of the plastid. Whilst a model for the mechanism of chloroplast division has been constructed, little is known of how other types of plastids divide, especially the proplastid, the progenitor of all plastid types in the cell.

Metabolic modeling of endosymbiont genome reduction on a temporal scale

Molecular Systems Biology, 2011
A fundamental challenge in Systems Biology is whether a cell‐scale metabolic model can predict patterns of genome evolution by realistically accounting for associated biochemical constraints.

Experimental uncoupling of hosts and endosymbionts

mBio
ABSTRACT Many organisms harbor heritable bacterial symbionts that offer context-specific benefits to their hosts. In some of these symbioses, symbionts live inside host cells as endosymbionts. Studying the biology of endosymbiosis is challenging because it is hard to independently cultivate hosts and ...

Ticks without borders: microbiome of immature neotropical tick species parasitizing migratory songbirds along northern Gulf of Mexico

Frontiers in Cellular and Infection Microbiology
IntroductionThe long-distance, seasonal migrations of birds make them an effective ecological bridge for the movement of ticks. The introduction of exotic tick species to new geographical regions can cause the emergence of novel tick-borne pathogens ...
