Fig. 4From: Comparative analysis of miRNA expression during the development of insects of different metamorphosis modes and germ-band typesChanges of miRNAs expression over B. germanica ontogenesis. a Expression of Mir-bg5b, Mir-252b and Mir-252a. b Expression of MIR-309 miRNAs compared to that seen in T. castaneum and D. virilis. c Number of miRNA genes significantly (p < 0.05) upregulated (green) or downregulated (red) at each stage transition. d Principal component analysis plot based on miRNA expression in the embryo, nymph and adult stages. The abbreviations for the stages are explained in Table 1 Back to article page
