Abstract
We have developed a web-based analysis tool, KaPPA-View, which enables to view transcriptome and metabolome data on the same metabolic pathway maps. Recently we released the latest version, KaPPA-View3. Although the previous version has equipped metabolic maps in which only Arabidopsis genes were assigned to the enzymatic reactions, KaPPA-View3 provides function to view gene expressions of multiple organisms. At present, genes of Lotus japonicus (Agilent), rice (Agilent) and tomato (Affymetrix) are assigned to the enzymatic reactions based on the sequence similarities to Arabidopsis. In KaPPA-View3, functions for gene co-expression analysis are also improved. In the previous version, representation function of inter-gene relationships was only available on a single pathway map. In KaPPA-View3, lines for gene-to-gene co-expressions are drawn between genes on at most four independent maps. Users' registered genes are represented as simple maps, facilitates to analyze co-expressions between non-metabolic genes such as transcription factors.
