  The chromosome-level genome of Mesobuthus martensii provides insights into its evolution and the diversity of venom peptides Abstract Mesobuthus martensii , the source species of the traditional Chinese medicine “Quanxie”, has long been utilized for its therapeutic properties. Venom peptides are recognized as the major active molecular basis of these pharmacological activities. Despite this, their development as therapeutic agents remains poorly explored. In this study, we performed an integrated multi-omics investigation to systematically explore the venom peptides of Mesobuthus martensii . We generated a chromosome-level genome assembly of Mesobuthus martensii using third-generation sequencing technologies, yielding a genome size of 1.08 Gb with a contig N50 of 46.46 Mb. Integrated genomic and transcriptomic analyses led to the identification of 51 putative novel venom peptide candidates. From the broader venom peptide set, five lysine- and arginine-rich candidates were select...

Survey of the Moroccan arachnids (Araneae, Scorpiones & Solifugae) in the collections of the Institute of Biodiversity and Ecosystem Research, Bulgaria

Abstract

Material belonging to a small collection of Moroccan arachnids housed in the Institute of Biodiversity and Ecosystem Research at the Bulgarian Academy of Sciences was examined and the results are presented here. A total of 28 species belonging to 16 families from three orders of arachnids were provided, as follows: Araneae (16 species, 12 families), Scorpiones (nine species, two families) and Solifugae (three species, two families). Five spider species, Adonea cf. fimbriata (Eresidae), Plexippus cf. clemens (Salticidae), Thanatus oblongiusculus (Philodromidae), Aelurillus aeruginosus (Salticidae) and Steatoda incomposita (Theridiidae), represent new or potential new records for the fauna of Morocco. Furthermore, the latter two are new for the African continent.
