Expression profile of certain mRNAs and miRNA of each class in the early embryogenesis of <i>Apis mellifera</i>.

<p>(A) Profile of mRNAs belonging to the three different classes of genes: I, II, and III. Examples of mRNAs from class I, II and III are plotted in a separated graphic for the haploid and diploid embryos. (B) Profile of miRNAs belonging to class I, II, and III. Note the differential expression and arm use among the embryo types (such as ame-<i>miR-184-3p</i> and <i>5p</i> of class II and ame-<i>miR-263-5p</i> of class II in haploids but class III in diploids). The total number of identified mRNAs for each class is as follows: class I, 667 in diploid and 475 in haploid embryos; class II, 2680 in diploid and 475 in haploid embryos; class III, 263 in diploid and 147 in haploid embryos. The total number of miRNAs for each class is as follows: class I, 90 in diploid and 72 in haploid embryos; class II, 23 in diploid and 24 in haploid embryos; class III, 37 in diploid and 67 in haploid embryos. Overall, the distribution demonstrates specific gene expression dynamics for mRNAs and miRNA in both types of embryos. The Expression and DEGseq output of the mRNAs and miRNAs plotted here are listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0146447#pone.0146447.s005" target="_blank">S5 Table</a>.
