VISTA is a collection of databases, tools, and servers that permit extensive comparative genomics analyses.


Background

The VISTA family of tools is developed and hosted at the Genomics Division of
Lawrence Berkeley National Laboratory Lawrence Berkeley National Laboratory (LBNL), commonly referred to as the Berkeley Lab, is a United States Department of Energy National Labs, United States national laboratory that is owned by, and conducts scientific research on behalf of, t ...
. This collaborative effort is supported by the Programs for Genomic Applications grant from the
NHLBI The National Heart, Lung, and Blood Institute (NHLBI) is the third largest Institute of the National Institutes of Health, located in Bethesda, Maryland, United States. It is tasked with allocating about $3.6 billion in FY 2020 in tax revenue to ...
/ NIH and the Office of Biological and Environmental Research, Office of Science, US Department of Energy. It was developed from modules supplied by developers at UC Berkeley, Stanford, and UC Davis, and based partly on the AVID Global Alignment program.


Usage

There are multiple VISTA servers, each allowing different types of searches. * can be used to align and compare your sequences to those of multiple other species * (regulatory VISTA) combines transcription factor binding sites database search with a comparative sequence analysis, the discovery of possible regulatory transcription factor binding sites in regions of their genes of interest. It can be used directly or through , Genome VISTA, or VISTA Browser. A database of tissue-specific human enhancers is available through VISTA Enhancer Browser. *GenomeVISTA allows the comparison of sequences with whole genome assemblies. It will automatically find the ortholog, obtain the alignment and VISTA plot. It allows the viewing of an alignment together with pre-computed alignments of other species in the same interval. *Phylo-VISTA allows the analysis of multiple DNA sequence alignments of sequences from different species while considering their phylogenic relationships. *wgVISTA allows the alignment of sequences up to 10Mb long (finished or draft) including microbial whole-genome assemblies. Researchers can use the VISTA Browser: *to examine pre-computed alignments among a variety of species *to submit sequences of their own (not limited by the species collection already in the database)


Genomes

There are more than 28 searchable genomes, including vertebrate, non-vertebrate, plants, fungi, algae, bacteria, and others. More are continually being added. These include: *Human—orangutan—rhesus—marmoset—horse—dog—mouse—rat—chicken *Drosophila spp. *Arabidopsis—rice—sorghum *E. coli—mycoplasma—nitrosomonas


Collaboration with other projects

Pre-computed full scaffold alignments for microbial genomes are available as the VISTA component of IMG ( Integrated Microbial Genomes System) developed in the DOE (Department of Energy's) Joint Genome Institute.
