Abstract

OrthoDB is a comprehensive catalog of orthologs, genes inherited by extant species from a single gene in their last common ancestor. In 2016 OrthoDB reached its 9th release, growing to over 22 million genes from over 5000 species, now adding plants, archaea and viruses. In this update we focused on usability of this fast-growing wealth of data: updating the user and programmatic interfaces to browse and query the data, and further enhancing the already extensive integration of available gene functional annotations. Collating functional annotations from over 100 resources, and enabled us to propose descriptive titles for 87% of ortholog groups. Additionally, OrthoDB continues to provide computed evolutionary annotations and to allow user queries by sequence homology. The OrthoDB resource now enables users to generate publication-quality comparative genomics charts, as well as to upload, analyze and interactively explore their own private data. OrthoDB is available from http://orthodb.org.

Summary

Introduction

Hypothesizing on gene functions is instrumental for many studies in molecular biology. OrthoDB continues to provide computed evolutionary annotations and to allow user queries by sequence homology. The web resource presenting the OrthoDB data enables identified user sessions to analyze custom data sets in the context of the available orthology data, as well as to generate publication quality comparative genomics reports.
