Fig. 1: Genomic structure and phylogeny of praying mantises.
From: Evolutionary genomics of camouflage innovation in the orchid mantis
A Photos of the juvenile orchid mantis H. coronatus (upper) and adult dead leaf mantis D. lobata (down) showing their adaptive camouflage. B Circos plot of chromosome-level genome assemblies of H. coronatus and D. lobata. From the inner circle to the outer circle, genome characteristics are indicated successively, including chromosome sizes (a), gene density (b), noncoding RNA density (c), repeat sequence distribution (d), GC content (e), SNP density (f), and homeobox gene clusters (g). C Composition comparison of the repetitive sequences of two mantises and the close relatives Blattella germanica and Zootermopsis nevadensis. The coordinates represent the percentage of the length of each category relative to the corresponding genome size. D Gene structure analysis showing that H. coronatus and D. lobata have larger average intron lengths than B. germanica, Z. nevadensis and Drosophila melanogaster. Abbreviations used throughout: Hcor, H. coronatus. Dlob, D. lobata. Bger, B. germanica. Znev, Z. nevadensis. Dmel, D. melanogaster. E Phylogenomic position of Mantodea. The estimated divergence times and the numbers of families with gene expansions (green) and contractions (red) are displayed on the branches of the phylogenetic tree. The 95% confidence interval of divergence time is indicated in brackets. Three calibration points (red circles) were applied as normal priors. The bootstrap values of most nodes were 100%.
