Figure Lengend Snippet: Signatures of genes suspected to be horizontally transferred from bacteria to leafhoppers. (A) Genome and transcriptome coverage of RdCDC9 ( Id09G000860 ). The read depths of genome resequencing and RNA sequencing data are log‐transformed and plotted along the focal genomic region, with numbers indicating the range of depths. Splice junctions in RdCDC9 inferred from the RNA sequencing reads are indicated by red lines. The two fragments used for PCR cloning of genomic DNA are represented as red segments. (B) Gene structures of the CDC genes in three leafhopper species. Green and pink rectangles represent the CDSs and UTRs, respectively, and the black lines represent introns. (C) Genome fragments cloned from Ne. cincticeps , Ne. nigropictus , and R. dorsalis genomic DNA. For the intron‐bearing genes RdCDC6 and RdCDC9 , two pairs of primers targeting the intron regions were used. Bar plots represent the expression levels of all CDCs detected by RT‐qPCR. (D) Identification of the RdCDC protein by immunoprecipitation‐mass spectrometry (IP‐MS). The R. dorsalis adult lysate was immunoprecipitated using IgG or an RdCDC9 antibody and analyzed by mass spectrometry to identify candidate proteins. (E) Hierarchical clustering results of CDC family members based on protein similarity. All genes from leafhoppers are clustered together and grouped with the CDCs from Firmicutes and Actinobacteria, suggesting that they may have originated from an ancient horizontal gene transfer event. The TCDB accession number and the common name or species of origin are provided for each protein used to construct the phylogeny. Predictions of the protein domains revealed that all leafhopper CDCs contained a region belonging to the thiol‐activated cytolysin superfamily (IPR036359). (F) Heatmap showing the average relative synonymous codon usage (RSCU) of leafhopper CDCs , bacterial CDCs ( PFO , LLO , and SLO ), and conserved single‐copy genes of the three leafhopper species. The gradient from dark blue to dark red indicates increasing RSCU values from low to high. LLO, listeriolysin O; PFO, perfringolysin O; SLO, streptolysin O.
