This review summarizes our present knowledge of chemoreceptor proteins in crustaceans, using a comparative perspective to these molecules crustaceans relative other metazoan models chemoreception including mammals, insects, nematodes, and molluscs. Evolution has resulted unique expansions specific gene families repurposing them for chemosensation various clades, crustaceans. A major class across is the Ionotropic Receptors, which diversified from ionotropic glutamate receptors ancient protostomes but are not deuterostomes. Representatives another proteins—the Grl/GR/OR family 7-transmembrane receptors—are insects date have been reported only one crustacean species, Daphnia pulex . So far, canonic G-protein coupled receptors, principal chemoreceptors vertebrates few protostome identified More types known throughout metazoans might well be expected discovered Our also provides coverage perireceptor events chemoreception, involved stimulus acquisition, delivery, removal, though much less about particularly at molecular level.

ABSTRACT Odorant‐binding proteins ( OBPs ) and chemosensory CSPs are regarded as carriers of pheromones odorants in insect chemoreception. These typically located antennae, mouth organs other structures; however, members both classes have been detected recently parts the body various functions proposed. The best studied these non‐sensory tasks is performed pheromone glands, where solubilise hydrophobic semiochemicals assist their controlled release into environment. In some cases same expressed antennae thus performing a dual role receiving broadcasting chemical message. Several reports described reproductive organs. Some male specific transferred to females during mating. They likely carry with different proposed roles, from inhibiting males approaching mated females, marking fertilized eggs, but further experimental evidence still needed.

The duplication of genes can occur through various mechanisms and is thought to make a major contribution the evolutionary diversification organisms. There increasing evidence for large-scale in some chelicerate lineages including two rounds whole genome (WGD) horseshoe crabs. To investigate this further, we sequenced analyzed common house spider Parasteatoda tepidariorum. We found pervasive both coding non-coding spider, clusters Hox genes. Analysis synteny conservation across P. tepidariorum suggests that there has been an ancient WGD spiders. Comparison with genomes other chelicerates, newly bark scorpion Centruroides sculpturatus, event occurred ancestor spiders scorpions, probably independent WGDs Furthermore, characterization sequence expression paralogs many have subject neo-functionalization and/or sub-functionalization since their duplication. Our results reveal scorpions are likely descendants polyploid lived more than 450 MYA. Given extensive morphological diversity ecological adaptations among these animals, rivaling those vertebrates, our study Arachnopulmonata provides new comparative platform explore divergent outcomes polyploidization events eukaryotes.

Bumblebees also invaluable natural and agricultural pollinators, there widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects bumblebee biology, including susceptibility implicated viability threats.We report high quality draft genome sequences Bombus terrestris impatiens, two ecologically dominant widely utilized study Comparing these new genomes those honeybee Apis mellifera other Hymenoptera, we identify deeply conserved similarities, as well novelties biology organisms. Some features thought underpin advanced eusociality present bumblebees, indicating an earlier bee lineage. Xenobiotic detoxification immune genes similarly depauperate honeybees, multiple categories linked organization, development behavior, show conservation. Key differences identified include a bias chemoreception towards gustation olfaction, striking microRNAs, potentially responsible for gene regulation underlying traits.These provide foundation post-genomic research on pollinators Overall, repertoires suggest that route bees was mediated by many small changes processes, not notable expansion or depauperation.

Dramatic adaptive changes in genes underlying production perception pheromones confirm importance chemical communication termites.

The evolutionary origins of the three major families chemoreceptors in arthropods-the odorant receptor (OR), gustatory (GR), and ionotropic (IR) families-occurred at base Insecta, Animalia, Protostomia, respectively. Comparison family sizes across arthropods reveals a generally positive correlation with their widely disparate complexity chemical ecology. Closely related species reveal ongoing processes gene evolution, including duplication, divergence, pseudogenization, loss, that mediate these larger patterns. Sets paralogous receptors within selection on amino acids regions likely to contribute ligand binding specificity. Ligands many ORs some GRs IRs have been identified; however, identification for more is needed, as are structures OR/GR superfamily, improve our understanding molecular evolution ecologically important arthropods.

Chemosensory-related gene (CRG) families have been studied extensively in insects, but their evolutionary history across the Arthropoda had remained relatively unexplored. Here, we address current hypotheses and prior conclusions on CRG family evolution using a more comprehensive data set. In particular, odorant receptors were hypothesized to proliferated during terrestrial colonization by insects (hexapods), association with other pancrustacean clades independent colonizations arthropod subphyla unclear. We also examine which is most ancient. Thus, reconstructed phylogenies of CRGs, including those from new genomes transcriptomes, mapped gains losses lineages. Our analysis was strengthened crustaceans, especially copepods, reside outside hexapod/branchiopod clade within subphylum Pancrustacea. generated first high-resolution genome sequence copepod Eurytemora affinis annotated its CRGs. found binding proteins present only hexapods (insects) absent all lineages, indicating that they are not universal adaptations land. Gustatory likely represent oldest chemosensory among dating back Placozoa. clarified confirmed antennal ionotropic Arthropoda.
