A comprehensive web tool about soybean functional gene network (SoyFGN) and microRNA functional network (SoymiRFN). SoyFN contains all 37827 genes of the release of UniprotKB version 111 and all 555 mature miRNAs of the latest release of miRBase (Release 19: August 2012). You can compute any pair of soybean genes or miRNAs and get genes' 3'-UTRs. By using Cytoscape Web, the user can easily view his/her interesting genes or miRNAs in a network. Also, KEGG pathway, motif and genome browser are incorporated to analysis other types of function of miRNA and target genes of Soybean.
