Fuzzy clustering analysis.

<p>All of the 7,467 “smoothed” expression profiles of the “cluster profile library” are distributed to eight fuzzy clusters. The x-axis represents the seven time points at which RNA was isolated from the three investigated <i>P. anserina</i> individuals. The y-axis indicates the relative expression strength. The color gradient corresponds to the membership value (see color bar on the right). A membership value of 1 means a perfect fitting to the corresponding cluster core (deep red). Arrows indicate the general tendency of the corresponding cluster. Below each cluster, a selection of categories to which significantly enriched GO terms (p-value ≤0.01) for particular functions were associated are listed (see description in the text).
