Aug 4, 2021 · We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.
Prashant P Sharma. Chelicerates exhibit dynamic evolution of genome architecture, with multiple whole genome duplication events affecting groups like spiders, scorpions, and horseshoe crabs.

Jan 11, 2021 · Developmental transcriptomes of the emerging model species Phalangium opilio have suggested that harvestmen do not exhibit systemic genome duplication, as evidenced by Hox gene complements (Sharma, Schwager, Extavour, & Giribet, 2012), absence of paralogy across the homeobox gene family (Leite et al., 2018), and gene expression patterns of singl...
Harvestmen differ from most mites by their larger size and by having the posterior body section distinctly segmented. Appearance. The most notable features of P. opilio and many other harvestmen are the long, slender legs and short, globular body.
Mar 4, 2022 · Research. Open access. Published: 04 March 2022. Eggs to long-legs: embryonic staging of the harvestman Phalangium opilio (Opiliones), an emerging model arachnid. Guilherme Gainett, Audrey R. Crawford, Benjamin C. Klementz, Calvin So, Caitlin M. Baker, Emily V. W. Setton & Prashant P. Sharma.
Nov 9, 2021 · Furthermore, we discovered conserved as well as divergent expression patterns of spider Wnt genes with respect to those of the harvestman Phalangium opilio, which did not have an ancestral WGD (Fig. 1 ).
Jan 11, 2021 · A staging system of P. opilio embryogenesis is presented that spans the most important morphogenetic events with respect to segment formation, appendage elongation and head development, and describes key events in segmentation, myogenesis, neurogenesis, and germ cell formation.
