Abstract

Large insert genomic DNA libraries are useful resources for genomic studies. Although the genome of Xenopus tropicalis stands as the amphibian reference genome because it benefitted from large-scale sequencing studies, physical mapping resources such as BAC libraries are lagging behind. Here we present the construction and characterization of a BAC library that covers the whole X. tropicalis genome. We prepared this BAC library from the genomic DNA of X. tropicalis females of the Adiopodoume strain. We characterized BAC clones by screening for specific loci, by chromosomal localization using FISH and by systematic BAC end sequencing. The median insert size is about 110kbp and the library coverage is around six genome equivalents. We obtained a total of 163,787 BAC end sequences with mate pairs for 77,711 BAC clones. We mapped all BAC end sequences to the reference X. tropicalis genome assembly to enable the identification of BAC clones covering specific loci. Overall, this BAC library resource complements the knowledge of the X. tropicalis genome and should further promote its use as a reference genome for developmental biology studies and amphibian comparative genomics.

摘要

大插入片段基因组DNA文库是基因组研究的有用资源。尽管热带爪蟾的基因组作为两栖动物参考基因组,受益于大规模测序研究,但诸如BAC文库等物理图谱资源却滞后了。在此,我们展示了一个覆盖热带爪蟾整个基因组的BAC文库的构建及特征分析。我们从阿迪奥波杜梅品系热带爪蟾雌性个体的基因组DNA制备了这个BAC文库。我们通过筛选特定基因座、使用荧光原位杂交进行染色体定位以及对BAC末端进行系统测序来鉴定BAC克隆。平均插入片段大小约为110kbp,文库覆盖率约为六个基因组当量。我们总共获得了163,787个BAC末端序列,其中77,711个BAC克隆具有配对末端。我们将所有BAC末端序列定位到热带爪蟾参考基因组组装上,以便鉴定覆盖特定基因座的BAC克隆。总体而言,这个BAC文库资源补充了热带爪蟾基因组的知识,并应进一步促进其作为发育生物学研究和两栖动物比较基因组学参考基因组的应用。
