Fig. 5
The gene movements in Lepidoptera. A The species tree with the stacked bars indicates the number of gene movements of different types (between autosomes, autosomes to Z chromosomes, Z chromosomes to autosomes, autosomes to W chromosomes, and Z chromosomes to W chromosomes) across Lepidoptera. B The species tree with the stacked bars indicates the number of Geminin located in Z chromosomes and autosomes across Lepidoptera. The black arrow represents the Geminin movement event that occurred between 152.1 and 141.7 Mya. C The gene tree of Geminin. Geminins located on Z chromosomes are marked with red. D Comparison of gene expression of the Geminin in 14 tissues and stages in silkworm. The average FPKM of biological repeats is shown in the figures. Male-biased expression is more evident in adults, marked with red. E Geminin location and expression in Lepidoptera and other order insects. The Capital letters with different colors represent the chromosomes Geminin located, and the sexual logo with different colors represents the expression biased type. Danaus plexippus and Acyrthosiphon pisum had two Geminin copies in other chromosomes. The average FPKM of biological repeats is shown in the figures. The picture shows the transcriptome analysis and qPCR results of the head of the adult silkworm and the transcriptome analysis results of the gonads of the adult monarch butterfly and the whole body of the adult fall armyworm. More information on the developmental stage and tissue for the transcriptome data for each species are given in Additional file 1: Tables S9 and S10
