Figure 2.
Phylogenetic tree inferred from the regions of the complete 18S and 28S rDNA sequences with conserved lengths.
The numbers associated with the nodes are posterior probability values (first number) and bootstrap values (second number) obtained by Bayesian/ML analysis respectively. The lengths of the branches follow the phylogram of the Bayesian tree.
Figure 3.
Consensus of the sequences of expansion segment D3-4 based on the homologues in GenBank.
The left column is the secondary structure of the D3-4 ‘marker-box’ of each polyneopteran order. The accession number in the bottom of each regional secondary structure stands for the corresponding sequence which is the same to the consensus sequence of each polyneopteran order or superorder. The middle column is the consensus result of the homologues in each polyneopteran order or superorder. The abscissa stand for the number of the bases, while the ordinate stand for the proportion of information content provided by each base in the same position. The right column is the number of sequences based on.

Secondary structure model of the 28S rRNA 5′-half of Zoraptera.
This sequence is from Zorotypus huxleyi [Genbank:JN192451]. The length-variable regions are indicated in red. And the unique indels are marked with green color. The D3-4 box was highlighted with thick red lines. The Da–Dj numbering system for LVRs, which has not been taken into account previously, is a supplementary system to the D1–D12 coding system. Base pairing is indicated as follows: standard canonical pairs by lines (C-G, G-C, A-U, U-A); wobble G·U pairs by dots (G·U); A·G and A·C pairs by open circles (A G, A C); other non-canonical pairs by filled circles (e.g., U•U).
