Number of A) differentially expressed transcripts (DETs), B) KEGG pathways with at least one DET, and C) enriched GO term unique to or shared between nourishment and caste datasets. Directionality, i.e. upregulated treatment group, is indicated for each dataset, where, for KEGG pathways and GO, terms, directionality is defined as the treatment group with the greater number of upregulated DETs per pathway or category, respectively. * indicates statistically significant overlap between nourishment and caste DETs (Chi-square test with Yates’ correction, p-value < 0.0001). ** indicates statistically significant overlap between nourishment and caste enriched GO terms (Fisher’s exact test, p-value = 4.4e-6). The fatty acid biosynthesis pathway had an equal number of DETs upregulated in the high and low nourishment groups (one per each group), so the directionality of this pathway is counted as one half for each group (indicated by †).
