Find evolutionarily related genes across insects and other arthropods on our new Ortholog webpages
NCBI recently released a set of orthologs for approximately 2 million insect genes. You can now find and access the orthologous genes, transcripts, and proteins by searching a species and gene name in NCBI All Databases, NCBI Gene, or NCBI Datasets. As previously described, these orthologs are based on comparisons to the Drosophila melanogaster annotated genome. Using Drosophila gene nomenclature for orthologs should lead to more informative gene symbols for insects and other arthropods.
Example: Getting insect orthologs for the Delta gene
Figure 1: Three ways to access orthologs for a gene: from the information box on an All Databases Search on the NCBI Homepage, from a Gene record page, and from the Datasets Gene service.
Figure 2: The orthologs page for the Delta gene filtered for members from the insect suborder Apocrita (wasps, ants, and bees).
Command-line access
Use NCBI Datasets command line (CLI) tool for programmatic access to orthologs. Download and install client. See our how-to-guide to get started.
