Camponotus floridanus transcriptome profiles separate by caste. (A) Sample distance heatmap and PCA analysis of our C. floridanus antennal transcriptome data. The sample distance heatmap (left) illustrates automated sample clustering and relationships between samples, with distance being reflected by the intensity of the colored squares. Caste is indicated by Mj (Major) and Mn (Minor), each sample being identified by a unique combination of caste and number. The PCA plot (right) demonstrates that a large proportion of variance (PC1, 43% of observed variance) is explained by caste (indicated by Condition), with Major (red) and Minor (blue) samples occupying different regions of the plot. (B) Normalized counts of the top 25 differentially-expressed olfactory receptor genes plotted to demonstrate the difference in expression pattern between Majors (red) and Minors (blue). In general, minors exhibit a trend of higher gene expression.
