Cluster analysis of gene expression based on log ratio RPKM data. (A) Heat map depicting the results of cluster analysis of the log ratio RPKM data. (B) A cluster that is enriched in genes involved in “cellular amino acid biosynthetic process.” (C) A cluster that is enriched in genes involved in “intraspecies interaction between organisms.” (D) A cluster that is enriched in genes involved in “cellular cell wall organization or biogenesis.” Green represents lower expression, red represents high expression, column represent individual experiments, and rows represent transcriptional units.
