Clustering of all 255 genes found in this poly P screen resolved distinct groups with similar poly P profiles. (a) Hierarchical clustering (uncentered Pearson correlation, complete linkage) of all log2-transformed data (relative to the wild-type). Clusters significantly enriched (P ≤ 0.05) for any GO Slim category are marked by colored bars and branches. (b) Average poly P values (log2-transformed, relative to the wild type) for all genes in the four distinct clusters in (a) at the four time-points.
