Efficient Integration of Phytozome Population Diversity and Expression Data with JBrowse

Phytozome (http://phytozome.jgi.doe.gov) is a plant comparative genomics web portal offering access to genome annotations and gene families for over 70 species from a diverse set of land plant and Chlorophyte/algal taxa. Our annotations are increasingly augmented by studies of gene expression across tissue types, developmental stages, and environmental conditions, and exploration of genetic diversity across natural and designed populations. Sample sizes continue to grow rapidly, posing unique challenges for visualization systems like JBrowse that perform graphical rendering within end-user web browser client software. Recent solutions to this problem are discussed, building on existing work to offer Phytozome users efficient display of this data in JBrowse while minimizing client-side data access and rendering resource consumption.
