[摘要]：Chinese pangolins as a representative species in the order Pholidota have highly specified morphological characters and occupy an important place in the mammalian phylogenetic tree. To obtain genomic data for this species, we have constructed a bacterial artificial chromosome (BAC) library of Chinese pangolin. The library contains 208,272 clones with an average insert size of 122.1 kb and represents approximately eight times the Chinese pangolin haploid genome (if we assume that the Chinese pangolins have a genome size similar to human). One hundred and twenty randomly-selected BAC clones were mapped onto Chinese pangolin chromosomes by fluorescence in situ hybridization (FISH), showing a largely unbiased chromosomal distribution. Several clones containing repetitive DNA and ribosomal DNA genes were also found. The BAC library and FISH mapped BAC clones are useful resources for comparative genomics and cytogenetics of mammals and in particular, the ongoing genome sequencing project of Chinese pangolins.
