  • A Beginner's Guide to Eukaryotic Genome Annotation
    REVIEWS STUDY DESIGNS A beginner’s guide to eukaryotic genome annotation Mark Yandell and Daniel Ence Abstract | The falling cost of genome sequencing is having a marked impact on the research community with respect to which genomes are sequenced and how and where they are annotated. Genome annotation projects have generally become small-scale affairs that are often carried out by an individual laboratory. Although annotating a eukaryotic genome assembly is now within the reach of non-experts, it remains a challenging task. Here we provide an overview of the genome annotation process and the available tools and describe some best-practice approaches. Genome annotation Sequencing costs have fallen so dramatically that a sin- with some basic UNIX skills, ‘do-it-yourself’ genome A term used to describe two gle laboratory can now afford to sequence large, even annotation projects are quite feasible using present- distinct processes. ‘Structural’ human-sized, genomes.

Permalink https://escholarship.org/uc/item/9j42z8fm Journal PloS one, 3(8) ISSN 1932-6203 Authors Bradnam, Keith R Korf, Ian Publication Date 2008-08-29 DOI 10.1371/journal.pone.0003093 Peer reviewed eScholarship.org Powered by the California Digital Library University of California Longer First Introns Are a General Property of Eukaryotic Gene Structure Keith R. Bradnam*, Ian Korf Genome Center, University of California Davis, Davis, California, United States of America Abstract While many properties of eukaryotic gene structure are well characterized, differences in the form and function of introns that occur at different positions within a transcript are less well understood. In particular, the dynamics of intron length variation with respect to intron position has received relatively little attention. This study analyzes all available data on intron lengths in GenBank and finds a significant trend of increased length in first introns throughout a wide range of species. This trend was found to be even stronger when using high-confidence gene annotation data for three model organisms (Arabidopsis thaliana, Caenorhabditis elegans, and Drosophila melanogaster) which show that the first intron in the 59 UTR is - on average - significantly longer than all downstream introns within a gene. A partial explanation for increased first intron length in A. thaliana is suggested by the increased frequency of certain motifs that are present in first introns. The phenomenon of longer first introns can potentially be used to improve gene prediction software and also to detect errors in existing gene annotations.

    Hu et al. BMC Bioinformatics (2018) 19:422 https://doi.org/10.1186/s12859-018-2443-4 SOFTWARE Open Access WebNetCoffee: a web-based application to identify functionally conserved proteins from Multiple PPI networks Jialu Hu1,2, Yiqun Gao1, Junhao He1, Yan Zheng1 and Xuequn Shang1* Abstract Background: The discovery of functionally conserved proteins is a tough and important task in system biology. Global network alignment provides a systematic framework to search for these proteins from multiple protein-protein interaction (PPI) networks. Although there exist many web servers for network alignment, no one allows to perform global multiple network alignment tasks on users’ test datasets. Results: Here, we developed a web server WebNetcoffee based on the algorithm of NetCoffee to search for a global network alignment from multiple networks. To build a series of online test datasets, we manually collected 218,339 proteins, 4,009,541 interactions and many other associated protein annotations from several public databases. All these datasets and alignment results are available for download, which can support users to perform algorithm comparison and downstream analyses. Conclusion: WebNetCoffee provides a versatile, interactive and user-friendly interface for easily running alignment tasks on both online datasets and users’ test datasets, managing submitted jobs and visualizing the alignment results through a web browser. Additionally, our web server also facilitates graphical visualization of induced subnetworks for a given protein and its neighborhood. To the best of our knowledge, it is the first web server that facilitates the performing of global alignment for multiple PPI networks. Availability: http://www.nwpu-bioinformatics.com/WebNetCoffee Keywords: Multiple network alignment, Webserver, PPI networks, Protein databases, Gene ontology Background tools [7–10] have been developed to understand molec- Proteins are involved in almost all life processes.

Parasites & Vectors (2018) 11:32 DOI 10.1186/s13071-017-2584-8 RESEARCH Open Access ASGDB: a specialised genomic resource for interpreting Anopheles sinensis insecticide resistance Dan Zhou, Yang Xu, Cheng Zhang, Meng-Xue Hu, Yun Huang, Yan Sun, Lei Ma, Bo Shen* and Chang-Liang Zhu Abstract Background: Anopheles sinensis is an important malaria vector in Southeast Asia. The widespread emergence of insecticide resistance in this mosquito species poses a serious threat to the efficacy of malaria control measures, particularly in China. Recently, the whole-genome sequencing and de novo assembly of An. sinensis (China strain) has been finished. A series of insecticide-resistant studies in An. sinensis have also been reported. There is a growing need to integrate these valuable data to provide a comprehensive database for further studies on insecticide-resistant management of An. sinensis. Results: A bioinformatics database named An. sinensis genome database (ASGDB) was built. In addition to being a searchable database of published An. sinensis genome sequences and annotation, ASGDB provides in-depth analytical platforms for further understanding of the genomic and genetic data, including visualization of genomic data, orthologous relationship analysis, GO analysis, pathway analysis, expression analysis and resistance-related gene analysis. Moreover, ASGDB provides a panoramic view of insecticide resistance studies in An. sinensis in China. In total, 551 insecticide-resistant phenotypic and genotypic reports on An. sinensis distributed in Chinese malaria- endemic areas since the mid-1980s have been collected, manually edited in the same format and integrated into OpenLayers map-based interface, which allows the international community to assess and exploit the high volume of scattered data much easier.
