Figure 2. Differential transcriptome analysis of DNA repair genes among castes. The heatmap shows the differential expression of 127 DNA repair transcripts among castes in Reticulitermes speratus. Workers and soldiers are non-reproductive individuals. Alates, young primary queens (PQs) and primary kings (PKs), and mature secondary queens (SQs) and PKs are reproductives. After nuptial flight, a pair of female and male alates establishes a new colony and starts to produce offspring sexually as a PQ and PK, respectively. The relative expression level is indicated by the mean normalized count per million, ranging from white to red. The tree at the left corresponds to the hierarchical clustering of cluster-averaged expression (clusters i–iv).
