“…Six genes of Wolbachia ( coxa, fbpa, ftsz, gatB, hcpA , and wsp ) infecting 127 Chorthippus parallelus from 21 populations inside and outside the grasshopper hybrid zone (Table 1) were sequenced following the multilocus system typing (MLST system) proposed by Baldo et al (2006b). As indicated above Wolbachia integrated sequences have been detected in C. parallelus nuclear genome (Funkhouser-Jones et al, 2015; Toribio-Fernández et al, 2017). However, different evidences rule out that they can introduce false positives in our analyses (see the Supplementary Material section for details).…”

“…Previous studies showed that the grasshopper subspecies diverged as a result of their geographic isolation in allopatry (Hewitt, 1993, 1999, 2001, 2011; Serrano et al, 1996) during the last glaciation. Recent cytogenetic data suggest that bacterial F strains and the ancestral C. parallelus came into contact before the hybrid zone was formed (Toribio-Fernández et al, 2017). In addition, the phylogeographical distribution of Wolbachia suggests a strong correlation between Wolbachia and its host's biogeography.…”

“…The physical mapping by FISH in the chromosomes of Cp of certain fragments of the Wolbachia genome of both supergroups (B and F) that have been laterally transferred into its nuclear genome is an additional cytogenetic finding about this interaction between Cp and Wolbachia (Toribio-Fernández et al, 2017). Some of these insertions are subspecies-specific, while others are present in both subspecies.…”

Wolbachia is a well-known endosymbiotic, strictly cytoplasmic bacterium. It establishes complex cytonuclear relations that are not necessarily deleterious to its host, but that often result in reproductive alterations favoring bacterial transmission. Among these alterations, a common one is the cytoplasmic incompatibility (CI) that reduces the number of descendants in certain crosses between infected and non-infected individuals. This CI induced by Wolbachia appears in the hybrid zone that the grasshoppers Chorthippus parallelus parallelus (Cpp) and C. p. erythropus (Cpe) form in the Pyrenees: a reputed model in evolutionary biology. However, this cytonuclear incompatibility is the result of sophisticated processes of the co-divergence of the genomes of the bacterial strains and the host after generations of selection and coevolution. Here we show how these genome conflicts have resulted in a finely tuned adjustment of the bacterial strain to each pure orthopteroid taxon, and the striking appearance of another, newly identified recombinant Wolbachia strain that only occurs in hybrid grasshoppers. We propose the existence of two superimposed hybrid zones: one organized by the grasshoppers, which overlaps with a second, bacterial hybrid zone. The two hybrid zones counterbalance one another and have evolved together since the origin of the grasshopper's hybrid zone.

Modern biotechnologies are applied to plants species (crops, flowers, trees), animals and microorganisms. The safety of the resulting transgenic organisms when released in the environment for their use in agriculture, forestry, the food and feed industry or for other applications represents a challenging issue. Genetically engineered products are rigorously assessed by their developers during their elaboration, and by governments when ready for release, to ensure high safety standards. This remains essential with new biotechnology developments using insects to fight against disease outbreaks: engineered mosquitoes need to be evaluated through a scientifically sound approach to risk/safety assessment that will inform biosafety regulators and support the decision concerning the release of these novel organisms in the environment. The OECD offers a long-standing recognised expertise in biosafety and contributes to facilitating an harmonised approach. The OECD's Working Group on Harmonisation of Regulatory Oversight in Biotechnology (WG-HROB) was established in 1995. The WG-HROB gathers national authorities responsible for the environmental risk/safety assessment of products of modern biotechnology in OECD countries and other economies. International organisations and experts involved in biosafety activities are associated with this programme. The primary goals of the WG-HROB are to promote international regulatory harmonisation, to ensure that methods used in the risk/safety assessment of genetically engineered products are as similar as possible. This may open the way to possible recognition and even acceptance of information from the assessments of other countries. The benefits of harmonisation are multiple: it strengthens mutual understanding among countries, avoids duplication, saves resources and increases the efficiency of the risk assessment process. Overall, it improves safety while reducing unnecessary barriers to trade. The environmental risk/safety assessment of transgenic organisms (biosafety assessment) is usually based on the information collected on the characteristics of the host organism, the introduced traits, the environment into which the organism will be released, the interaction between these, and the intended use of the organism for agriculture, forestry, food and feed industry, health improvement or other purposes. Since its establishment, the WG-HROB decided to focus its work on identifying parts of this information which could be commonly used among countries when conducting environmental risk/safety assessment, aiming to encourage information sharing and prevent duplication of effort among countries. Biosafety consensus documents are one of the major outputs of its work. The OECD Biosafety consensus documents are intended to be a "snapshot" of current information on a specific host organism or trait, for use during regulatory assessments of organisms considered for their release in the environment. These publications are not designed to be a comprehensive source of information on everythin...
