MITEs preferentially inserted in gene flanking regions and play important roles in genome diversity. a The distribution of MITEs inserted in upstream and downstream of gene regions in three Citrus species. b The relative abundance of MITEs in different genomic regions. c The stable and unstable MITEs in 6 Citrus species. d A MITE uniquely inserted into 5′ UTR of C. grandis genome. e A MITE uniquely inserted into intron of C. grandis genome. f A MITE uniquely inserted into C. grandis genome, and a gene is annotated in the insertion region. (d-f: Gray shading represents collinear regions. Blue shading represents collinear MITE regions. Orange large rectangles, small rectangles and lines respectively represent CDS, UTR and intron. Blue rectangles and inverted triangle respectively represent MITE and MITE absence loci)
