“…The presence of the biotin operon among the Wolbachia appears rare, but when present, its physical organization appears conserved among them (Figure 3). Phylogenetic analysis of the biotin gene cluster supports the suggestion that the biotin operons were acquired by lateral transfer from endosymbiotic bacteria, such as Cardinium species, as previously suggested [50,51]. The lack of congruence between the phylogeny of the biotin operons and Wolbachia phylogeny suggests multiple independent transfers of the operon within Wolbachia evolutionary history.…”

“…Interestingly, wCle provisions biotin (but not thiamin), which significantly contributes to the fitness of host bedbug [49]. In planthoppers, wLug and wStri Wolbachia appear to increase the fecundity of their hosts, which may be related to a beneficial effect of Wolbachiasynthesized biotin and riboflavin [51]. It is tempting to speculate that this pathway in wApol may also be important in the the association between Wolbachia and its pseudoscorpion hosts.…”

“…Until recently, only wCle (Wolbachia from bedbug Cimex lectularius) contains a complete pathway for biotin (vitamin B7) [49]. More recently, a complete pathway for biotin was identified in wNfla and wNleu (supergroup A) [50], as well as in wLug and wStri (supergroup B) [51]. Interestingly, wCle provisions biotin (but not thiamin), which significantly contributes to the fitness of host bedbug [49].…”

Abstract Background Wolbachia are the most widely spread endosymbiotic bacteria, present in a wide variety of insects and two families of nematodes, but as of now, relatively little genomic data has been available. The Wolbachia symbiont can be parasitic, as described for many arthropod systems, an obligate mutualist, as in filarial nematodes or a combination of both in some organisms. They are currently classified into 16 monophyletic lineage groups ("supergroups"). Although the nature of these symbioses remains largely unknown, expanded Wolbachia genomic data will contribute to understanding their diverse symbiotic mechanisms and evolution. Results This report focuses on Wolbachia infections in three pseudoscorpion species infected by two distinct groups of Wolbachia strains , based upon multi-locus phylogenies. Geogarypus minor harbours w Gmin and Chthonius ischnocheles harbours w Cisc, both closely related to supergroup H, while Atemnus politus harbours w Apol, a member of a novel supergroup S along with Wolbachia from the pseudoscorpion Cordylochernes scorpioides ( w Csco), most closely related to Wolbachia supergroups C and F. Using target enrichment by hybridization with Wolbachia -specific biotinylated probes to capture large fragments of Wolbachia DNA, we produced two draft genomes of w Apol. Annotation of w Apol highlights presence of a biotin operon, which is incomplete in many sequenced Wolbachia genomes. Conclusions The present study highlights at least two symbiont acquisition events among pseudoscorpion species. Phylogenomic analysis indicates that the Wolbachia from Atemnus politus ( w Apol), forms a separate supergroup ("S") with the Wolbachia from Cordylochernes scorpioides (w Csco). Interestingly, the biotin operon, present in w Apol, appears to have been horizontally transferred multiple times along Wolbachia evolutionary history.

“…The somatic Wolbachia distribution in insects may be associated with more functions, including, but not limited to, manipulating host reproduction (Pietri et al, 2016). Wolbachia infections increase the fecundity of L. striatellus by provisioning biotin and riboflavin (Ju et al, 2019). As the most dominant symbiont in L. striatellus and S. furcifera, the effects of Wolbachia on host biology should be more thoroughly studied.…”

Rice planthoppers are notorious plant sap‐feeding pests which cause serious damage. While several microbes in rice planthoppers have been broadly characterized, the abundance and diversity of bacteria and fungi in field planthoppers are largely unknown. This study investigated the bacterial and fungal community compositions of Chinese wild rice planthoppers Laodelphax striatellus and Sogatella furcifera using parallel 16S rRNA gene amplicon and internal transcribed space region sequencing. The bacteria varied significantly between the species and were partitioned significantly by sex, tissues and host environments in each species. The majority of bacteria were affiliated with the genera Wolbachia, Cardinium, Rickettsia and Pantoea. The abundance of Wolbachia was negatively correlated with that of Cardinium in both planthopper species. Compared with bacteria, the abundance and diversity of fungi did not differ between sexes but both were enriched in the gut. The bacterial community as a whole showed no significant correlation with the fungal community. The majority of fungi were related to Sarocladium, Alternaria, Malassezia, Aspergillus and Curvularia. A phylogenetic analysis revealed that these fungi were closely related to botanic symbionts or pathogens. Our results provide novel insights into the bacteria and fungi of rice planthoppers.

“…For the Vitamin B pathways, it was previously determined that only wCle (Wolbachia from bedbug Cimex lectularius) contained a complete pathway for biotin (vitamin B7) and for thiamine (vitamin B1) [55]. More recently, a complete pathway for biotin was identified in wNfla and wNleu (supergroup A) [41] , as well as, wLug and wstri (supergroup B) [56]. wApol has the same pathways (with the exception of the gene bioC).…”

Abstract Background Wolbachia are the most widely spread endosymbiotic bacteria, present in a wide variety of insects and two families of nematodes, but so far, relatively little genomic data is available. The Wolbachia symbiont can be a parasite, as described for many arthropods, or an obligate mutualist, as in filarial nematodes. Although, the nature of these symbioses remains largely unknown, diverse Wolbachia genomic data will contribute to understanding their diverse symbiotic mechanisms. Results Our study focuses on Wolbachia infections in pseudoscorpion species collected in Montpellier (France) and indicates two distinct groups of Wolbachia : Geogarypus minor harbors Wolbachia ( w Gmin) and Chthonius ischnocheles harbors Wolbachia ( w Cisc), both related to supergroup H and Atemnus politus harbours Wolbachia ( w Apol), forming a novel divergent clade with Wolbachia from the pseudoscorpion Cordylochernes scorpioides . This later clade forms a new supergroup S, most closely related to Wolbachia supergroups C and F. Our data suggest multiple symbiont acquisition events within the evolutionary history of pseudoscorpions. Using target enrichment by hybridization with Wolbachia -specific biotinylated probes to capture large fragments of Wolbachia DNA, we produced a draft genome of w Apol characterized by a moderate Wolbachia size (1,445,964bp) containing a moderate number of transposable elements and WO bacteriophage insertions (total of 77,522 bp). Conclusions Our analyses indicate that w Apol forms a diverget clade. Annotation highlights complete biochemical pathways which are incomplete in many sequenced Wolbachia genomes, such as vitamin B and the cytochrome bd ubiquinol oxidase pathway. Further, the biotin operon appears to have been horizontally transferred multiple times along the Wolbachia evolutionary history.
