Differential expressions of CTLDs, GNBPs and PGRPs among castes.
These heatmaps indicate the differential expression of 29 genes belonging to the CTLD superfamily, the GNBP family and PGRPs among termite castes (PQ: primary queen, PK: primary king, SQ: secondary queen). Relative expression level indicates the mean normalized count per million (CPM), ranging from black (scaled expression of 0) to white (scaled expression of 2.5). The tree at the left corresponds to hierarchical clustering of cluster-averaged expression. Numbers in parentheses after caste names refer to the numbers of biological replicates. Ten individuals were pooled for each sex of worker and soldier to obtain sufficient amounts of RNA, while single individuals were used for RNA extraction in the other castes. CTL: C-type lectin-like domain protein, LPSBP: lipopolysaccharide-binding protein, GNBP: Gram-negative binding protein, PGRP: peptidoglycan recognition protein.
Fig 2.
Differential expression of serine proteases among castes.
The heatmap indicates the differential expression of 70 serine protease transcripts among castes. Abbreviations are as indicated in Fig 1. Relative expression level indicates the mean normalized CPM, ranging from black (scaled expression of 0) to white (scaled expression of 3.0). The tree at the left corresponds to hierarchical clustering of cluster-averaged expression.
Fig 3.
Differential expression of cathepsins among castes.
The heatmap indicates the differential expression of 10 cathepsin transcripts among castes. Abbreviations are as indicated in Fig 1. Relative expression level indicates the mean normalized CPM, ranging from black (scaled expression of 0) to white (scaled expression of 3.0). The tree at the left corresponds to hierarchical clustering of cluster-averaged expression.
Fig 4.
Differential expression of lysozymes among castes.
The heatmap indicates the differential expression of 9 lysozyme transcripts among castes. Abbreviations are as indicated in Fig 1. Relative expression level indicates the mean normalized CPM, ranging from black (scaled expression of 0) to white (scaled expression of 2.75). The tree at the left corresponds to hierarchical clustering of cluster-averaged expression.
