Understanding Complex Data through Better Visualization

Recently, researchers at JCVI reported on the Rhizoctonia solani mitochondrial genome which was the largest fungal mitochondrion to be sequenced to date. We showed that its unusually large size was probably due to the expansion of multiple genetic elements that populated the genome in somewhat of a ‘parasitic’ relationship. The visualization was meant to impress the number and variety of these repetitive genetic elements, and was selected in a commentary in  FEMS Microbiology Letters as an example of how to summarize molecular data in order to obtain an overall view of the results.

The outermost circle represents the chromosome and repetitive elements. Other important features such as genes, endonucleases, exons, RNAseq coverage are represented in the concentric circles respectively. Grey links represent short repeats (< 35bp) found up to 100 times in the genome; colored links show the location of repeats and follow the coloration in Track 1.
