Figure 3From: Comparative analysis of microarray data in Arabidopsis transcriptome during compatible interactions with plant virusesSimilarity matrix ( S ij ) reflecting changes in the Arabidopsis transcriptome in response to different Arabidopsis -virus interactions. The higher the value of the S ij , the more similarity exists between two compared virus-host interactions. Each cell represents an individual virus-host interaction S ij , color-delineated according to the level of similarity ranging from considerable (red) to weak (dark blue).Back to article page
