KaPPA-View 4: Kazusa Plant Pathway Viewer

This web-based tool, KaPPA-View4, represents -omics data on plant metabolic pathway maps that users upload. Differences in gene expressions and metabolite accumulation between samples are visually represented as hue of the gene and metabolite symbols. gene-to-gene and metabolite-to-metabolite relationships, including correlation coefficients of gene co-expressions can be overlayed on the pathway maps. This helps to better understand transcripts and metabolites when examining the roles of genes in the metabolic pathway. The system has been revised, and the processing speed was improved compared to previous versions. Both Windows and Mac OS X are fully supported now and all features of the database are available. Users can use their own metabolic pathway maps for analyses. After uploading DNA microarray or metabolite data, fitting data for each gene or compound is displayed on a metabolic pathway map.
