2013年末,《科学家》(The Scientist)杂志盘点了 2013 年度的高引基因组研究论文,一起来了解下有哪些基因组论文受到了研究人员的热捧。
斑马鱼基因组
种属:Zebrafish, Danio rerio
基因组大小:~1.41 billion base pairs
斑马鱼(Danio rerio)是广泛用于遗传学、发育和疾病研究的重要模式生物,其透明胚胎特别容易观察。此外,这种小鱼既容易培养成本又低。近十年来,人们在不断完善斑马鱼的基因组草图。不过直到今年四月,人们才最终获得了高质量的斑马鱼参考基因组。
来自英国桑格研究所的科学家们,在斑马鱼的基因组中发现了26,000个蛋白编码基因,这是已测序脊椎动物中最多的。研究显示,斑马鱼70%的基因与人类基因直系同源。他们在同期Nature上还发表了另一篇文章,通过诱变和测序,在斑马鱼基因组中鉴定了10,000多个蛋白编码基因的功能。研究人员希望,高质量的斑马鱼基因组,能够帮助人们增进对人类疾病的认识。(详细报道 Nature:系统解析斑马鱼参考基因组)

挪威云杉
种属:Norway spruce, Picea abies
基因组大小:19.6 billion base pairs
挪威云杉(Picea abies)广泛分布于北半球,是第一个被测序的裸子植物,其基因组发表在五月份的Nature杂志上。研究显示,挪威云杉拥有巨大的基因组,但其中只有28,000个基因,数量与拟南芥差不多(拟南芥的基因组只有135 million bp)。研究人员发现,形成这种超大基因组是因为,挪威云杉无法有效清除转座子元件。随后,他们对另外五种针叶树进行测序,并将这些低覆盖度的基因组草图与云杉基因组进行比较。研究显示,转座子元件在这类植物中非常普遍。“这些树的基因组序列,不仅能帮助我们理解过去,还可以增进我们对目前北半球森林的理解,”北卡罗来纳州立大学的Ronald Sederoff说。(详细报道 Nature:科学家完成云杉超大基因组草图)

古老的腔棘鱼
种属:African coelacanth, Latimeria chalumnae
基因组大小:~2.86 billion base pairs
四月份Nature发布了非洲腔棘鱼(Latimeria chalumnae)的基因组,引起了进化生物学家的强烈兴趣,这种动物的形态与陆生脊椎动物的鱼类祖先非常相似。腔棘鱼曾被认为已在七千万年前灭绝,直到上世纪三十年代,人们才在南非发现了一只。自此以后,人们总共只找到过309条腔棘鱼。研究人员测序了腔棘鱼的基因组,发现与肺鱼、鸡和哺乳动物相比,其蛋白编码基因演化得非常慢。此外,与腔棘鱼相比,肺鱼与四足动物的亲缘更近。
研究显示,腔棘鱼与四足脊椎动物共享的一个DNA片段,可能启动了四肢的进化。该DNA片段能促进一个基因簇的表达,而该基因簇涉及了手指、手腕、脚踝和脚趾中的骨头形成。文章指出,这些基因可能帮助陆生动物的鱼类祖先,生成适应陆地的四肢。(详细报道 Nature:脊椎动物进化里程碑 腔棘鱼基因组测序完成)
