Abstract Background In recent years, acetic acid bacteria have been shown to be frequently associated with insects, but knowledge on their biological role in the arthropod host is limited. The discovery that of genus Asaia are a main component microbiota Anopheles stephensi makes this mosquito useful model for studies novel group symbionts. Here we present experimental results provide first evidence beneficial An. . Results Larvae at different stages were treated rifampicin, an antibiotic...
Wolbachia is a group of intracellular maternally inherited bacteria infecting high number arthropod species. Their presence in different mosquito species has been largely described, but Aedes aegypti, the main vector Dengue virus, never found naturally infected by Wolbachia. Similarly, malaria vectors and other anophelines are normally negative to Wolbachia, with exception an African population where these have recently detected. Asaia acetic acid bacterium stably associated several species,...
Stones in arid environments are inhabited by actinobacteria of the family Geodermatophilaceae like genera Blastococcus and Modestobacter frequently isolated from altered calcarenites. Their habitat requires adaptation to light-induced other stresses that generate reactive oxygen species. Here, we show representative members species saxobsidens, Geodermatophilus obscurus, multiseptatus differentially adapted associated with environments. Whereas B. saxobsidens was found be sensitive gamma...
Abstract Two of the largest crude oil-polluted areas in world are semi-enclosed Mediterranean and Red Seas, but effect chronic pollution remains incompletely understood on a large scale. We compared influence environmental geographical constraints anthropogenic forces (hydrocarbon input) bacterial communities eight geographically separated sites along coastlines Seas. The differences community compositions their biodegradation potential were primarily associated (P < 0.05) with both...
ABSTRACT Following cultivation-dependent and -independent techniques, we investigated the microbiota associated with Bactrocera oleae , one of major agricultural pests in olive-producing countries. Bacterial 16S rRNA gene libraries ultrastructural analyses revealed presence several bacterial taxa this insect, among which Acetobacter tropicalis was predominant. The recent increased detection acetic acid bacteria as symbionts other insect model organisms, such Anopheles stephensi (G. Favia et...
Rhynchophorus ferrugineus, also known as the red palm weevil, is regarded major pest of trees. Although studies microbiota associated with this species have been performed in recent years, little attention has dedicated to influence diet shaping host bacterial community. Here, we investigated food sources (i.e. tissues vs apple based substrate) on microbial diversity RPW, which was compared wild individuals sister vulneratus. The characterization using a culture independent approach, i.e....
ABSTRACT The recent increased detection of acetic acid bacteria (AAB) the genus Asaia as symbionts mosquitoes, such Anopheles spp. and Aedes spp., prompted us to investigate diversity these their relationships in different mosquito species populations. Following cultivation-dependent -independent techniques, we investigated microbiota associated with four species, stephensi , gambiae aegypti albopictus which are important vectors human and/or animal pathogens. Denaturing gradient gel...
Abstract Intracellular reproductive manipulators, such as Candidatus Cardinium and Wolbachia are vertically transmitted to progeny but rarely show co-speciation with the host. In sap-feeding insects, plant tissues have been proposed alternative horizontal routes of interspecific transmission, experimental evidence is limited. Here we report results from experiments that horizontally between different phloem insect species through plants. Quantitative PCR in situ hybridization indicated...
Abstract Various bacterial taxa have been identified both in association with animals and the external environment, but extent to which related bacteria from two habitat types are ecologically evolutionarily distinct is largely unknown. This study investigated scale pattern of genetic differentiation between family Acetobacteraceae isolated guts Drosophila fruit flies, plant material industrial fermentations. Genome‐scale analysis phylogenetic relationships predicted functions was conducted...
The pivotal role of diet in shaping gut microbiota has been evaluated different animal models, including insects. Drosophila flies harbour an inconstant among which acetic acid bacteria (AAB) are important components. Here, we investigated the bacterial and AAB components invasive pest suzukii microbiota, by studying same insect population separately grown on fruit-based or non-fruit artificial diet. were highly prevalent under both diets (90 92% infection rates with fruits respectively)....
Summary While symbiosis between bacteria and insects has been thoroughly investigated in the last two decades, investments on study of yeasts associated with have limited. Insect‐associated are placed different branches phylogenetic tree fungi, indicating that these associations evolved independently several occasions. Isolation is frequently reported from insect habitats, some cases detected gut other organs/tissues. Here we show yeast Wickerhamomyces anomalus , previously known as Pichia...
The ancestors of mitochondria, or proto-mitochondria, played a crucial role in the evolution eukaryotic cells and derived from symbiotic α-proteobacteria which merged with other microorganisms - basis widely accepted endosymbiotic theory. However, identity relatives proto-mitochondria remain elusive. Here we show that methylotrophic could be closest living models for mitochondrial ancestors. We reached this conclusion after reconstructing possible evolutionary pathways bioenergy systems...
Various intracellular bacterial symbionts that provide their host with essential nutrients have much-reduced genomes, attributed largely to genomic decay and relaxed selection. To obtain quantitative estimates of the metabolic function these bacteria, we reconstructed genome- transcriptome-informed models three xylem-feeding insects bear two complementary functions: a primary symbiont, Sulcia, has codiversified insects, coprimary symbiont distinct taxonomic origin different degrees genome...
Popillia japonica Newman (Coleoptera: Scarabaeidae) is a highly polyphagous invasive beetle originating from Japan. This insect resilient and able to rapidly adapt new vegetation. Insect-associated microorganisms can play important roles in physiology, helping their hosts changing conditions potentially contributing an insect's potential. Such symbiotic bacteria be part of core microbiota that stably transmitted throughout the host's life cycle or selectively recruited environment at each...
Here we report the full genome sequence of Modestobacter marinus strain BC501, an actinobacterial isolate that thrives on stone surfaces. The generated chromosome is circular, with a length 5.57 Mb and G+C content 74.13%, containing 5,445 protein-coding genes, 48 tRNAs, 3 ribosomal operons.
Members of the genus Blastococcus have been isolated from sandstone monuments, as well sea, soil, plant, and snow samples. We report here genome sequence a member this genus, saxobsidens strain DD2, below surface Sardinian wall calcarenite stone sample.
Abstract Diversity and composition of lepidopteran microbiotas are poorly investigated, especially across the different developmental stages. To improve this knowledge, we characterize microbiota among stages Indian meal moth, Plodia interpunctella , which is considered one major pest commodities worldwide. Using culture‐independent approach based on Illumina 16S rRNA gene sequencing characterized four stages: eggs, first‐, last‐instar larvae, adult. A total 1022 bacterial OTUs were...
