Analysis of differential expression of unigenes associated with transcription. Pairwise comparison of differentially expressed unigenes involved in transcriptional regulation (a), phosphorylation (b) and DNA methylation (c). The significance in each comparison pair is indicated using log-transformed P-value (red); the dark gray areas represent missing values.
