Figure 2 - Transcriptome comparison between sexual and asexual population. A) Two-dimensional principal component analysis based on head transcriptomes from sexual (black) and asexual (red) populations. Samples, based on the expression profile of 14,106 genes, clustered according to population. B) Volcano plot illustrated variations in gene expression between sexual and asexual populations, the y axis measured the statistical significance (FDR) while the x axis indicated the magnitude of change. Grey points represented the 1,539 DEG, while genes not differentially expressed were represented by blue dots including thefor gene pointed in red. C) Comparison of normalized counts number of the for gene between the 3 asexual (red) and 3 sexual (black) RNA-seq libraries.
Table 2 – Behavioural genes belonging to the DEGs between sexual and asexual populations. Among the 1539 DEGs between sexual and asexual populations, 26 transcripts were annotated has related to behaviour GO term, or one of its child GO terms. The population in which the transcript was overexpressed was indicated as well as its fold change (log2), with positive values when overexpressed in sexual population, and negative values in asexual population.
