An increasing number of microbial genomes are being sequenced and deposited in public databases. In addition, several closely related strains are also being sequenced in order to understand the genetic basis of diversity and mechanisms that lead to the acquisition of new genetic traits. These exercises have necessitated the requirement for visualizing microbial genomes and performing genome comparisons on a finer scale. We have developed GenomeViz to enable rapid visualization and subsequent comparisons of several microbial genomes in an interactive environment.
Here we describe a program that allows visualization of both qualitative and quantitative information from complete and partially sequenced microbial genomes. Using GenomeViz, data deriving from studies on genomic islands, gene/protein classifications, GC content, GC skew, whole genome alignments, microarrays and proteomics may be plotted. Several genomes can be visualized interactively at the same time from a comparative genomic perspective and publication quality circular genome plots can be created.
GenomeViz should allow researchers to perform visualization and comparative analysis of up to eight different microbial genomes simultaneously.
越来越多的微生物基因组被测序并存入公共数据库。此外,为了了解多样性的遗传基础以及导致获得新遗传特性的机制,人们也在对几种密切相关的菌株进行测序。这些工作使得可视化微生物基因组并在更精细的尺度上进行基因组比较成为必要。我们开发了GenomeViz,以便在交互式环境中快速可视化并随后比较多个微生物基因组。
在此我们描述了一个程序,该程序能够可视化来自完整和部分测序的微生物基因组的定性和定量信息。使用GenomeViz,可以绘制来自基因组岛、基因/蛋白质分类、GC含量、GC偏移、全基因组比对、微阵列和蛋白质组学研究的数据。从比较基因组学的角度,可以同时交互式地可视化多个基因组,并创建具有发表质量的环形基因组图。
GenomeViz应能让研究人员同时对多达八个不同的微生物基因组进行可视化和比较分析。
