Science: 利用HI-C 3D基因组组装虫媒基因组

2017-04-16 MedSci MedSci原创

研究人员利用一种名叫“3D基因组组装”的突破性技术,组装出了传播寨卡病毒和西尼罗病毒的两种蚊虫的3条染色体。研究人员Hi-C数据与现有的草稿组合进行组合,以生成染色体长度的scaffold。并且通过组装人类基因组(从头到尾)从单纯阅读(67X覆盖)来验证这种方法。然后研究人员用该方法与草图序列相结合,以组装埃及伊蚊和致倦库蚊的基因组。这些组件表明,这些物种中几乎所有的基因组重排都发生在染色体臂内,

近日,来自美国休斯顿贝勒医学院基因组中心的研究人员报道了一项利用Hi-C技术进行3D基因组组装技术研究传播寨卡病毒的蚊虫基因组的研究,相关研究成果刊登于国际杂志Oncotarget上。

研究人员利用一种名叫“3D基因组组装”的突破性技术,组装出了传播寨卡病毒和西尼罗病毒的两种蚊虫的3条染色体。研究人员Hi-C数据与现有的草稿组合进行组合,以生成染色体长度的scaffold。并且通过组装人类基因组(从头到尾)从单纯阅读(67X覆盖)来验证这种方法。然后研究人员用该方法与草图序列相结合,以组装埃及伊蚊和致倦库蚊的基因组。这些组件表明,这些物种中几乎所有的基因组重排都发生在染色体臂内,而不是在染色体臂之间。

该研究表明,研究中所描述的基因组装配程序快速,便宜,准确,并可应用于许多物种。
