In Release 20.0 we have updated data from FlyBase to release FB2009_08 and updated several data sets to their most recent versions. Also we have added pathways from Reactome for fly, yeast and worm. We’ve added a pathway enrichment widget to each gene list analysis page. Please see the pathways section of FlyMine for more details. In addition, we have added new data for CDNA clones and fixed a few minor bugs in the webapp.
