The western clawed frog Xenopus tropicalis is an important model for vertebrate development that combines experimental advantages of the African clawed frog Xenopus laevis with more tractable genetics. Despite the genomic revolution, the first complete genome of a frog, Xenopus tropicalis, was sequenced only in 2010. To clone the first anion channel from Xenopus laevis (X. laevis), we isolated a calcium-activated chloride channel (CLCA)-like membrane protein 6 gene (CMP6) in X. laevis.As a first step in gene isolation, an expressed sequence tags database was screened to find the partial cDNA fragment. Xenopus laevis (v9.1 genome assembly) L sub-genome, and (iii) XLA.S: X. laevis S sub-genome. The current version is named 'JGI 7.1' at XenBase, and 'JGIv7b' at UTA web repository('daudin'). Xenopus tropicalis provides a simpler model for genetic studies, having a diploid genome. In the last few years, numerous reports have demonstrated that TALENs are able to induce mutations in F0 Xenopus embryos, but none has demonstrated germline transmission of such mutations in X. laevis. The NXR is funded by an award from the … The complete sequence of the 17,553-nucleotide Xenopus laevis mitochondrial genome has been determined. Although the genome of Xenopus tropicalis has been sequenced and published, other genomic tools and resources are still needed. There is a wealth of data in the literature on gene function, full-length cDNA sequences and in situ databases on laevis, but no genome sequence or genetics. Genome duplication has played a pivotal role in the evolution of many eukaryotic lineages, including the vertebrates. Hello! The selected BACs include ~70 genes of interest (Shroom3, Wnt5a, Glypican-4, Noggin, Gremlin, Pax6, Formin, etc., as initially identified by the group of Jan-Fang Cheng via probing the CHORI-219 library), as well as 10 BACs that have already been sequenced by the DOE Joint Genome Institute/HudsonAlpha Genome Sequencing Center to serve as positive controls for the sequencing and assembly pipeline. We show that during this period, DNA replication proceeds in an atypical manner. When the Joint Genome Institute decided to sequence a frog genome, however, the Xenopus research community recommended X. tropicalis over X. laevis because tropicalis has half the genome size. They display remarkable structural similarity with the human genome (Hellsten et al. They may use data in publications focused around individual genes.
