非模式真核生物小基因组注释的现代工具

Modern tools for annotation of small genomes of non-model eukaryotes

Marina Galchenkova, Aleksei Korzhenkov

摘要:

如今,由于测序获得的实验数据越来越多,最感兴趣的是确定其基因组的各个部分的功能和特征,而不是确定基因组的核苷酸序列。基因组注释包括识别编码和非编码序列,确定基因的结构和确定这些序列的功能。尽管在使用测序数据的计算技术方面取得了重大成就,但由于一些基因组部分的功能的大量未解决的分子确定,因此没有通用的方法来进行基因组的功能注释。科学界正在努力解决这个问题。本文综述了现有的真核生物基因组注释方法。本文包括绪论、正文和讨论三个主要部分。介绍了真核生物基因组注释的独立工具和自动流水线的发展,并结合原核生物基因组注释的现有成果。主体由两个不同的部分组成,第一个是专门用于注释非模型真核生物基因组的说明,第二个块是关于需要最少用户的策展的自动管道的最新版本。简要说明了评估注释基因组的质量和完整性的问题,并讨论了进行这种分析的工具。目前,还没有一个通用的自动软件用于真核基因组注释,涵盖了整个任务列表,无需人工管理或使用额外的外部工具和资源。因此,它导致的任务,开发一个更广泛的功能和通用的协议,自动注释的小真核生物基因组。

英文摘要:

Nowadays, due to the increasing amount of experimental data obtained by sequencing, the most interest is focused on determining the functions and characteristics of its individual parts of the genome instead of determining the nucleotide sequence of the genome. The genome annotation includes the identification of coding and non-coding sequences, determining the structure of the gene and determining the functions of these sequences. Despite the significant achievements in computational technologies working with sequencing data, there is no general approach to the functional annotation of the genome in the reason of the large number of unresolved molecular determination of the function of some genomes parts. Nevertheless, the scientific community is trying to solve this problem. This review analyzed existing approaches to eukaryotic genome annotation. This work includes 3 main parts: introduction, main body and discussion. The introduction reflects the development of independent tools and automatic pipelines for annotation of eukaryotic genomes, which are associated with existing achievements in annotating prokaryotic ones. The main body consists of two distinguished parts, the first one is devoted to instructions for annotating genomes of non-model eukaryotes, and the second block is about recent versions of automatic pipelines that require minimal user's curation. The question of assessing the quality and completeness of the annotated genome is noted briefly, and the tools to conduct this analysis are discussed. Currently, there is no universal automatic software for eukaryotic genome annotation, covering the whole list of tasks, without manual curation or using additional external tools and resources. Thus it leads to the task of developing a wider functional and universal protocol for automatic annotation of small eukaryotic genomes.
