Abstract Thoracican barnacles are a diverse group of marine organisms for which the availability genome assemblies is currently limited. In this study, we sequenced genomes two neolepadoid species ( Ashinkailepas kermadecensis , Imbricaverruca yamaguchii ) from hydrothermal vents, in addition to intertidal species. Genome sizes ranged 481 1054 Mb, with repetitive sequence contents 21.2% 50.7%. Concordance rates orthologs and heterozygosity were between 82.4% 91.7% 1.0% 2.1%, respectively, indicating high genetic diversity heterozygosity. Based on phylogenomic analyses, revised nomenclature cement genes encoding proteins that not homologous any known proteins. The major gene, CP100A was found all thoracican species, including vent‐associated neolepadoids, hypothesised be essential settlement. Duplicated genes, CP100B CP100C only balanids, suggesting potential functional redundancy or acquisition new functions associated calcareous base. An ancestor CP52 duplicated dynamically among lepadids, pollicipedids multiple copies single scaffold, balanids sequential repeats conserved regions, but no providing insights into gene evolution lineages. This study enhances our understanding adhesion mechanisms thoracicans underwater environments. newly provide opportunities studying their ecology, shedding light adaptation environments, contributing knowledge barnacle biology valuable genomic resources further studies field.

Abstract Background Apostichopus japonicus is an economically important species in the global aquaculture industry. Russian A. , mainly harvested Vladivostok region, exhibits significant phenotypic differentiation, including many traits, compared with Chinese owing to differences their habitat. However, both genetic basis for divergence and population structure of are unknown. Result In this study, 210 individuals from seven populations were sampled whole-genome resequencing. The analysis differentiated into two groups. Population analyses indicated that showed a high degree allelic linkage had undergone stronger positive selection populations. Gene ontology terms enriched among candidate genes group involved immunity, such as inflammatory response, antimicrobial peptides, humoral apoptosis. Genome-wide association yielded eight single-nucleotide polymorphism loci significantly associated parapodium number, these located regions genomic differentiation between Russia These SNPs five genes. expression validation revealed three differentially expressed differing number. AJAP08772 AJAP08773 may directly affect production by promoting endothelial cell proliferation metabolism, whereas AJAP07248 indirectly affects participating immune responses. Conclusions This we performed GWAS on found related number parapodium. results provide in-depth understanding China Russia, information subsequent breeding species.

Barnacles interest the scientific community for multiple reasons: their unique evolutionary trajectory, vast diversity and economic impact-as a harvested food source also as one of most prolific macroscopic hard biofouling organisms. A common, yet novel, trait among barnacles is adhesion, which has enabled sessile adult existence global colonization oceans. Barnacle adhesive primarily composed proteins, but knowledge how proteome varies across tree life unknown due to lack genomic information. Here, we supplement previous mass spectrometry analyses barnacle with recently sequenced genomes compare proteomes Pollicipes pollicipes (Pedunculata) Amphibalanus amphitrite (Sessilia). Although both species contain same broad protein categories, detail differences that exist between these species. The barnacle-unique cement proteins show greatest difference species, although are diminished when amino acid composition glycosylation potential considered. By performing an in-depth comparison distantly related similarities provide roadmap future studies examining sequence-specific identify responsible functional life.

Abstract Barnacle adhesion is a focus for fouling-control technologies as well the development of bioinspired adhesives, although mechanisms remain very poorly understood. The barnacle cypris larva responsible surface colonisation. Cyprids release cement from paired glands that contain proteins, carbohydrates and lipids, further compositional details are scant. Several genes coding gland-specific proteins were identified, but only one these showed database homology. This was lysyl oxidase-like protein (lcp_LOX). LOX-like enzymes have been previously identified in proteome adult secretory tissue. We attempted to produce recombinant LOX E. coli , order identify its role cyprid polymerisation. also produced two other gland (lcp3_36k_3B8 lcp2_57k_2F5). lcp2_57k_2F5 contained 56 lysine residues constituted plausible substrate LOX. While significant quantities soluble lcp3_36k_3B8 production stably lcp_LOX failed. A commercially sourced human catalysed crosslinking into putative dimers trimers, this reaction inhibited by lcp3_36k_3B8. Inhibition lcp_LOX:lcp2_57k_2F5 appeared be specific, with no inhibitory effect on oxidation cadaverine results demonstrate possible curing mechanism and, thus, provide basis more complete understanding larval targeted control marine biofouling adhesives niche applications.
