PlantArrayNet

What is PlantArrayNet?

PlantArrayNet (PAN), a new version of RiceArrayNet (Lee et al., 2009), provides co-expression information between genes in terms of correlation coefficients from accumulated microarray data. Given the correlation of a gene pair, the degrees of closeness between gene expression profiling are calculated and are visualized in a relational tree and a relational network. In addition, PAN supports scatter plots of log ratios between genes and links them to pathway maps, while providing a common cis-element list of promoter regions that are involved.
