Figure 1.
Differential expression analyses between midgut and salivary gland samples of A. gambiae. (A) Volcano plots displaying changes in gene expression, isoforms, and TSS usage (log2-fold change). Each symbol represents one gene that has detectable expression in either tissue. Relative differences in signal intensity along the X-axis reflect up-regulation in salivary glands when positive and up-regulation in midguts when negative. The Y-axis displays log10-transformed p-values associated with tests of differential gene expression; red symbols indicate significant values for a threshold level of 0.05. (B) Density plots showing the expression level distribution for all genes, isoforms, and TSS, in the two tissues. FPKM, fragments per kb of transcript per million fragments mapped.
