Distance heatmaps and PCAs of our Atta cephalotes and A. sexdens antennal transcriptome data. (A) The sample distance heatmap (left) illustrates automated sample clustering and relationships between A. cephalotes samples, and the PCA plot (right) demonstrates that samples cluster by caste (indicated by Condition) across different regions of the plot. Caste is abbreviated for labeling purposes (DW = Dump Worker, For = Forager, Mi = Minima, Sol = Soldier), with each sample being identified by a unique combination of caste and number. (B) The sample distance heatmap (left) and the PCA plot (right) demonstrate poor clustering between A. sexdens samples or castes. As in (A), caste is abbreviated for labeling purposes (For = Forager, Sol = Soldier), with each sample being identified by a unique combination of caste and number.
