Genomes
VectorBase is committed to a new release every two months with all data freely available for public use based on NIH/NIAID policy. A list of these changes and the state of current versions on this date (e.g., current gene sets) can be found on the Releases section of VectorBase.
For your species of interest, click on Organism, Strain, Assembly, or Gene set to find the Genome Browser link (which looks like this: ).
Released genomes, with gene predictions
In this release the genome assemblies for Anopheles farauti, Anopheles melas, Anopheles merus and Anopheles sinensis were updated to the latest versions, and the gene sets for sandflies Phlebotamus papatasi, and Lutzomyia longipalpis have moved from pre-release to full release status. Community supplied gene annotations were also updated for the anophelines Anopheles farauti, Anopheles funestus, Anopheles melas, Anopheles merus and Anopheles sinensis, and the for the sandflies Phlebotamus papatasi, Lutzomyia longipalpis. A new organism Glossina palpalis has also been added in this release.
For the four Anopheline species with new assemblies, genes were projected from the old assemblies via an assembly alignment with ATAC. For Anopheles farauti, 13,469 (98.2%) transcripts were projected; for Anopheles melas, 15,851 (95.1%); for Anopheles merus, 13,806 (95.7%); and for Anopheles sinensis 13,331 (87.3%). For each species a set of files is available which contains full details of the transcripts that did/didn't get projected (and why). The README files (e.g. for An. farauti) describe the projection methodology and outline the resources available for reinstating genes that were unable to be projected automatically. A track has been added to the WebApollo instances for these species showing unprojected transcripts that partially map to the new assembly.
Thirty whole genome alignments were generated for this release. Six of these alignments are between the new species Glossina palpalis and the other Glossinidae + Musca domestica. Nine realignments were necessary within the gambiae complex, due to the new assemblies for Anopheles melas and Anopheles merus. Finally, 15 tBLAT alignments were replaced by LASTZ alignments. LASTZ typically gives about twice the coverage for non-coding regions, and increases coverage in coding regions by a lesser, but still significant amount (up to about 10%). Statistics on coverage for each pairwise alignment are available via the complete list of alignments.
Expression Data
The Aedes aegypti RNA-seq expression data from the publication Evolution of mosquito preference for humans linked to an odorant receptor by McBride and coauthors is now available in the Expression Browser. The data is represented in VectorBase as two "experiments":
Population Biology/Insecticide Resistance
Several large datasets have been overhauled to improve the storage and representation of species and inversion genotype data. More specifically projects VBP0000003, VBP0000005, VBP0000006 and VBP0000008 have had their inversion genotype representation improved so that the inverted allele counts are now available for all genotyped samples. An issue with our species taxonomy has been corrected, such that samples from these projects are now correctly assigned to species based on their Scott and Favia/Fanello PCR tests. Several minor curation issues were fixed in other projects.
Variation Data
New data
New variation data added for Anopheles farauti, Anopheles melas, Anopheles merus and Anopheles sinensis from the paper "Mosquito genomics. Highly evolvable malaria vectors: the genomes of 16 Anopheles mosquitoes."
