Abstract

The cat flea, Ctenocephalides fells, is widely recognized as a global veterinary pest and a vector of pathogenic bacteria. We recently reported on the C. felis nuclear genome, which is characterized by over 38% protein coding gene duplication, extensive tRNA gene family expansion, and remarkable gene copy number variation (CNV) between individual fleas. Herein, we describe the assembly of the C. felis mitochondrial genome, a novel resource for comparative genomics of fleas and other insects. The order and content of mitochondrial genes is highly consistent with four previously sequenced flea mitochondrial genomes, limiting CNV to siphonapteran nuclear genomes.

猫蚤（ Ctenocephalides fols ）被广泛认为是一种全球性兽医害虫和病原菌载体。我们最近报道了C 。猫科动物核基因组，其特点是超过 38% 的蛋白质编码基因重复、广泛的 tRNA 基因家族扩展以及个体跳蚤之间显着的基因拷贝数变异 (CNV)。在这里，我们描述了C的组装。猫科动物线粒体基因组，跳蚤和其他昆虫比较基因组学的新资源。线粒体基因的顺序和内容与之前测序的四种跳蚤线粒体基因组高度一致，将CNV限制在管翅目核基因组中。
