在复制起点处启动DNA复制对于基因组的复制是必不可少的。在酵母中,复制起点的自主复制序列(ARS)特性对于附加型质粒的稳定维持是必需的。然而,由于ARS功能的序列决定因素在酵母物种之间不同,目前的ARS模块仅限于用于酵母的子集。在这里,我们描述了一个短的ARS序列,在至少10个不同种类的芽殖酵母的功能。这些包括但不限于跨越超过5亿年进化的酵母属、拉茜西亚属、克鲁维酵母属和毕赤酵母属(Komagataella)的成员。除了其广泛的物种范围外,该ARS和优化的衍生物相对于其他目前使用的ARS模块赋予改善的质粒稳定性。
The initiation of DNA replication at replication origins is essential for the duplication of genomes. In yeast, the autonomously replicating sequence (ARS) property of replication origins is necessary for the stable maintenance of episomal plasmids. However, because the sequence determinants of ARS function differ among yeast species, current ARS modules are limited for use to a subset of yeasts. Here we describe a short ARS sequence that functions in at least 10 diverse species of budding yeast. These include, but are not limited to members of the Saccharomyces, Lachancea, Kluyveromyces, and Pichia (Komagataella) genera spanning over 500 million years of evolution. In addition to its wide species range, this ARS and an optimized derivative confer improved plasmid stability relative to other currently used ARS modules.
