Age-dependent antennal transcript abundance. a Principal component analysis of the antennal transcriptomes of 5 to 10 days post-emergence (dpe) female Aedes aegypti. Ages are denoted by a gradient of green hues, with the lightest being 5 dpe and the darkest being 10 dpe. The total number of genes with differentially abundant transcripts from comparisons between b each age group and 5 dpe, and c adjacent ages of host-seeking adult female Ae. aegypti can be determined by the sum of those with gene ontology (GO) annotation (white) and those without (green). d-e Proportions of genes with differentially abundant transcripts in the antennae of 5 to 10 dpe host-seeking adult female Ae. aegypti classified by a level 3 molecular function gene ontology. Comparisons are made between each age group and 5 dpe (d), and adjacent age groups (e). The legend indicates the GO terms representing ≥2% of the total differentially abundant transcripts in at least one pairwise comparison
