哺乳动物基因组学的进展并不均衡,一半是树懒,一半是猎豹,这是由于各种技术障碍,包括真核生物基因组的复杂性,难以从野生动物中获得高质量的DNA,以及相互矛盾的进化特征。2022年完成的端粒到端粒(T2T)人类基因组组装是由超长读取测序技术推动的,这只是二十年前最初的草案发表时的梦想。在不同的哺乳动物物种中产生高质量的基因组现在是可能的,从而能够探索紧密包装的,调节的和重复的DNA区域。哺乳动物世界包括6500个现存物种和超过1.8亿年的基因组进化,研究的时机已经成熟。在本期的第366、364、371、372、363和365页,Christmaset al.,Kaplowet等人,Osmanski等人,Wilderet等人,穆奈等人,和福莱耶等人,利用Zoonomia Consortium的240个物种基因组的新数据集来研究胎盘哺乳动物之间的分子,种群和物种水平的变化,探索这一基因组前沿。
Mammal genomics has progressed at an uneven pace—half sloth, half cheetah—owing to various technical obstacles, including the complexity of eukaryotic genomes , difficulties obtaining high-quality DNA from wild animals , and conflicting evolutionary signatures . The 2022 completion of the telomere-to-telomere (T2T) human genome assembly was fueled by ultralong-read sequencing techniques only dreamt of two decades ago when the initial draft was published. Generating high-quality genomes across diverse mammal species is now possible, enabling the exploration of tightly packed, regulatory, and repetitive DNA regions. The mammalverse comprises ∼6500 living species and >180 million years of genome evolution, ripe for investigation . On pages 366, 364, 371, 372, 363, and 365 of this issue, Christmaset al., Kaplowet al., Osmanskiet al., Wilderet al., Moonet al., and Foleyet al., respectively, explore this phylogenomic frontier, using the Zoonomia Consortium’s new dataset of 240 species’ genomes to investigate molecular-, population-, and species-level changes among placental mammals.
