Abstract:
Rails are a phenotypically diverse family of birds that includes 130 species and displays a wide distribution around the world. Here we present annotated genome assemblies for four rails from Aotearoa New Zealand: two native volant species, pūkeko Porphyrio melanotus and mioweka Gallirallus philippensis, and two endemic flightless species takahē Porphyrio hochstetteri and weka Gallirallus australis. Using the sequence read data, heterozygosity was found to be lowest in the endemic flightless species and this probably reflects their relatively small populations. The quality checks and comparison with other rallid genomes showed that the new assemblies were of good quality. This study significantly increases the number of available rallid genomes and will enable future genomic studies on the evolution of this family.
摘要:
Rails是一个表型多样化的鸟类家族,包括130种,分布在世界各地。在这里,我们介绍了来自Aotearoa新西兰的四个Rails的注释基因组组装:两个本地的野生物种,黑色素卟啉和菲律宾米奥韦卡Gallirallus,和两个特有的不会飞行的物种takahñPorphyriohochstetteri和wekaGallirallusaustralis。使用序列读取数据,在特有的无飞行物种中,杂合性最低,这可能反映了它们相对较小的种群。质量检查以及与其他rallid基因组的比较表明,新的装配体质量良好。这项研究显着增加了可用的rallid基因组的数量,并将使将来对该家族的进化进行基因组研究。
