A 'Variant Viewer' for investigating population-level variation in Arabidopsis thaliana

Abstract

High throughput sequencing has opened the doors for investigators to probe genetic variation present in large populations of organisms. In plants, the 1001 Genomes Project (1001genomes.org) is one such effort that sought to characterize the extant worldwide variation in Arabidopsis thaliana for future analyses to compare and draw upon. We developed a web application that accesses the 1001 Genomes database called The Variant Viewer, for investigators to view variants in any A. thaliana gene and within gene families. These variants may be visualized in the context of alignments of queried genes, across splice isoforms of these genes and in relation to conserved domains.
