K-means clustering for differentially expressed unigenes across four stages (a) and functional classification within clusters (b). a The y-axis is the base-2 logarithm of the mean of normalized counts of three biological replicates. The number of unigenes in each cluster is indicated. b Clusters from left to right: from the most abundant K10 to the least abundant K11. * indicates enriched categories according to Fisher’s test (p-value ≤0.05)
