  • New X. laevis 9.2 and X. tropicalis 9.1 GFFs

    Xenbase GFF tracks for X. laevis 9.2 and X. tropicalis 9.1 official genomes are now available on Xenbase FTP and GitLab account!

    View on JBrowse: trop and laevis.
    GFFs were created by merging NCBI and JGI GFF files.

  • Digital dissection of Xenopus laevis using contrast-enhanced computed tomography

    Porro and Richards published in the Journal of Anatomy their detailed views of adult Xenopus laevis anatomy. View their visualizations of skeletal and muscular anatomy; the nervous, respiratory, digestive, excretory and reproductive systems; and the major sense organs.

  • The Zahn Drawings

    A new developmental series for Xenopus, ‘the Zahn drawings’ and a complementary set of bright field photographs have been published in Development. These drawings provide researchers with views of the tadpole stages during cranial development, NF stage 22-50.

  • Sorting at embryonic boundaries requires high heterotypic interfacial tension

    Canty et al. published in Nature Communications their study investigating the underlying mechanisms of cell sorting of ectoderm-mesoderm separation during early embryonic development.

  • Mitotic chromosome assembly despite nucleosome depletion in Xenopus egg extracts

    Shintomi et al. expolited a cell-free system made from Xenopus laevis eggs. Combined with nucleosome-depleted mouse nuclei, they investigate mitotic chromatid structure assembly of DNA in the absence of histones. Published in Science.

  • In Situ Microprobe Single-Cell Capillary Electrophoresis Mass Spectrometry

    Metabolic Reorganization in Single Differentiating Cells in the Live Vertebrate (Xenopus laevis) Embryo.

    Onjiko et al. published in Analytical Chemistry their study peering, for the first time, into the formation of metabolic single-cell heterogeneity during early development of a vertebrate embryo.

  • Integration of over 9,000 mass spectrometry experiments builds a global map of human protein complexes

    Drew et al. integrate the largest-scale mass spectrometry protein interaction datasets from a variety of human and animal cells and tissues. The machine-learning framework generates the most comprehensive and accurate human protein complex map to date. Published in Molecular Systems Biology.

  • Genome evolution in the allotetraploid frog Xenopus laevis

    Session et al. published in Nature describe the analysis of the subgenomes of the allotetraploid Xenopus laevis. The L subgenome more consistenly resembles the ancestral condition and the S subgenome is more disrupted by deletion and rearrangment.
