Fig. 4From: Population mixing mediates the intestinal flora composition and facilitates invasiveness in a globally invasive fruit flyTranscriptomic analyses of the inbred and outbred populations. A Volcano map, the horizontal coordinate indicates the change in the gene expression (inbred vs. outbred population) (log2 fold change); the vertical coordinate indicates the significance level (-log10 (P-value)). The upregulated genes and downregulated genes are presented by red and green dots, respectively. Grey represents no significant difference. B The GO functions of significantly different genes were enriched in the outbred population of B. dorsalis. MF stands for molecular function, BP for biological processes and CC for cell components. C Significantly downregulated gene expression in outbred populations. D Intestinal transcriptome metabolic pathway mapBack to article page
