摘要

DNA测序能力的提高极大地促进了我们对鸟类系统发育及其基因组多样性形成的近因和最终机制的理解。在不到十年的时间里,鸟类参考基因组的数量已经增加到500多个,约占鸟类多样性的5%,这使得鸟类在系统基因组学、比较基因组学、功能基因组学和种群基因组学领域处于有利地位。全基因组序列数据,以及索引和罕见的基因组变化,正在进一步解决鸟类生命树的问题。鸟类基因组的积累,以及越来越多的长读序列数据,极大地提高了生殖系限制性染色体和W染色体等基因组特征的分辨率,并促进了基因型和表型的比较整合。以社区为基础的计划,如鸟类10,000基因组计划和脊椎动物基因组计划,在扩大和整合一个充满活力的国际鸟类比较基因组学计划方面发挥着重要作用。预计《生态、进化和分类学年度评论》第52卷的最终在线出版日期为2021年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

What Have We Learned from the First 500 Avian Genomes?
The increased capacity of DNA sequencing has significantly advanced our understanding of the phylogeny of birds and the proximate and ultimate mechanisms molding their genomic diversity. In less than a decade, the number of available avian reference genomes has increased to over 500—approximately 5% of bird diversity—placing birds in a privileged position to advance the fields of phylogenomics and comparative, functional, and population genomics. Whole-genome sequence data, as well as indels and rare genomic changes, are further resolving the avian tree of life. The accumulation of bird genomes, increasingly with long-read sequence data, greatly improves the resolution of genomic features such as germline-restricted chromosomes and the W chromosome, and is facilitating the comparative integration of genotypes and phenotypes. Community-based initiatives such as the Bird 10,000 Genomes Project and Vertebrate Genome Project are playing a fundamental role in amplifying and coalescing a vibrant international program in avian comparative genomics. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 52 is November 2021.

期刊介绍: The Annual Review of Ecology, Evolution, and Systematics is a scholarly publication that has been in circulation since 1970. It focuses on important advancements in the areas of ecology, evolutionary biology, and systematics, with relevance to all forms of life on Earth. The journal features essay reviews that encompass various topics such as phylogeny, speciation, molecular evolution, behavior, evolutionary physiology, population dynamics, ecosystem processes, and applications in invasion biology, conservation, and environmental management. Recently, the current volume of the journal transitioned from a subscription-based model to open access through the Annual Reviews' Subscribe to Open program. Consequently, all articles published in the current volume are now available under a CC BY license.
