Transcriptomic Correlates Of Caste Differentiation And Invasiveness In A Subterranean Termite, Tian Wu
Transcriptomic Correlates Of Caste Differentiation And Invasiveness In A Subterranean Termite, Tian Wu
Electronic Thesis and Dissertation Repository
Termite colonies are characterized by a division of labour into reproductive and helper castes (soldiers and workers). Caste differentiation is associated with differences in gene expression that reflect developmental and evolutionary origins. I used RNA-seq to investigate genome-wide expression patterns of reproductive nymph, soldier, and worker castes of Reticulitermes flavipes from three populations. I found 93 genes differentially expressed as a function of caste, with the majority of genes being uniquely up-regulated in soldiers. My findings suggest that soldiers evolved genes that are distinct from nymphs and workers, and are signs of possible genomic novelty. I also analyzed this transcriptome …
