Fauna Europaea – Orthopteroid orders
Pensoft Publishers, 2016Co-Authors: Heller Klaus-gerhard, Bohn Horst, Haas Fabian, Willemse Fer, De Jong YdeAbstract:Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant European terrestrial and freshwater animals, their geographical distribution at the level of countries and major islands (west of the Urals and excluding the Caucasus region), and some additional information. The Fauna Europaea project comprises about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. Fauna Europaea represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. The "Orthopteroid orders" is one of the 58 Fauna Europaea major taxonomic groups. It contains series of mostly well-known insect orders: Embiodea (webspinners), Dermaptera (earwigs), Phasmatodea (walking sticks), Orthoptera s.s. (grasshoppers, crickets, bush-crickets) and Dictyoptera with the suborders Mantodea (mantids), Blattaria (cockroaches) and Isoptera (termites). For the Orthopteroid orders, data from 35 families containing 1,371 species are included in this paper

A pheromone-binding protein from the cockroach Leucophaea maderae: cloning, expression and pheromone binding
Biochemical Journal, 2003Co-Authors: Stéphane Riviere, A. Lartigue, Brigitte Quennedey, V. Campanacci, Jean-pierre Farine, M. Tegoni, C. Cambillau, Rémy BrossutAbstract:Odorant-binding proteins (OBPs) are thought to transport volatile compounds from air to their receptors through the sensillary lymph. In this protein family, the subgroup of pheromone-binding proteins (PBPs) is specifically tuned to the perception of the sexual pheromone. To date, the description of OBPs has been restricted to Endopterygota and Paraneoptera. Their expression in Orthopteroid has been hypothesized, but no evidence of OBP has been produced in this assemblage to date. In the present study, we describe the first OBP from a Dictyopteran insect that belongs to the cockroach Leucophaea maderae. The PBP of L. maderae (PBPLma) shares all the hallmarks of the OBP family and is expressed specifically in the female adult antennae, the sex that perceives the sexual pheromone. The affinity of the recombinant PBPLma produced in the Escherichia coli periplasm for the pheromonal compounds has been tested by displacement of a fluorophore, 8-anilino-1-naphtalenesulphonic acid (ANS). Our results suggest that two chemically close compounds of the pheromonal blend (3-hydroxy-butan-2-one and butane-2,3-diol) are capable of displacing ANS, whereas two other pheromone components (E-2-octenoic acid and senecioic acid) and other alkyl volatile compounds are not capable of displacing ANS, indicating a certain filtering of binding, which can be correlated with the putative function.

the mitochondrial genome of bacillus stick insects phasmatodea and the phylogeny of Orthopteroid insects
Molecular Phylogenetics and Evolution, 2011Co-Authors: Federico Plazzi, Andrea Ricci, Marco PassamontiAbstract:Abstract The Order Phasmatodea (stick and leaf insects) includes many well-known species of cryptic phytophagous insects. In this work, we sequenced the almost complete mitochondrial genomes of two stick insect species of the genus Bacillus. Phasmatodea pertain to the Polyneoptera, and represent one of the major clades of heterometabolous insects. Orthopteroid insect lineages arose through rapid evolutionary radiation events, which likely blurred the phylogenetic reconstructions obtained so far; we therefore performed a phylogenetic analysis to resolve and date all major splits of Orthopteroid phylogeny, including the relationships between Phasmatodea and other polyneopterans. We explored several molecular models, with special reference to data partitioning, to correctly detect any phylogenetic signal lying in rough data. Phylogenetic Informativeness analysis showed that the maximum resolving power on the Orthopteroid mtDNA dataset is expected for the Upper Cretaceous, about 80 million years ago (Mya), but at least 70% of the maximum informativeness is also expected for the 150–200 Mya timespan, which makes mtDNA a suitable marker to study Orthopteroid splits. A complete chronological calibration has also been computed following a Penalized Likelihood method. In summary, our analysis confirmed the monophyly of Phasmatodea, Dictyoptera and Orthoptera, and retrieved Mantophasmatodea as sister group of Phasmatodea. The origin of Orthopteroid insects was also estimated to be in the Middle Triassic, while the order Phasmatodea seems to appear in the Upper Jurassic. The obtained results evidenced that mtDNA is a suitable marker to unravel the ancient splits leading to the Orthopteroid orders, given a proper methodological approach.

Chorthippus parallelus and Wolbachia: Overlapping Orthopteroid and Bacterial Hybrid Zones.
Frontiers in genetics, 2018Co-Authors: Paloma Martínez-rodríguez, José L. BellaAbstract: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.

Chromosomal localization of Wolbachia inserts in the genomes of two subspecies of Chorthippus parallelus forming a Pyrenean hybrid zone
Chromosome Research, 2017Co-Authors: Raquel Toribio-fernandez, Paloma Martínez-rodríguez, José L. Bella, Lisa J. Funkhouser-jones, Seth R. Bordenstein, Miguel PitaAbstract:Wolbachia are endosymbiotic bacteria of arthropods and nematodes that can manipulate the reproduction of various host organisms to facilitate their own maternal transmission. Moreover, Wolbachia's presence in host germ cells may contribute to the many cases of lateral gene transfer from Wolbachia to host genomes that have been described. A previous study in Chorthippus parallelus, a well-known Orthopteroid forming a hybrid zone in the Pyrenees, identified Wolbachia sequences from two major supergroups in the genomes of infected and uninfected Chorthippus parallelus parallelus (Cpp) and Chorthippus parallelus erythropus (Cpe) subspecies. In this study, we map the Wolbachia genomic inserts to specific regions on the chromosomes of Cpp and Cpe by fluorescent in situ hybridization (FISH) using tyramides to increase the accuracy and detection of these insertions. Additionally, we consider some of the possible roles that these bacterial inserts play in the organization and function of the grasshopper genome, as well as how they can serve as markers for phylogenetic relationships of these organisms.
