Fig. 6From: The repetitive DNA landscape in Avena (Poaceae): chromosome and genome evolution defined by major repeat classes in whole-genome sequence readsRelative proportions and an evolutionary model of repetitive DNA motifs in common oat genomes. a Relative proportion of repeats in A. hirtula, A. brevis, and A. strigosa genomes denoted by pink, yellow, and blue columns, respectively. b Evolutionary model of repetitive DNA motifs. Red, blue, and light green characters denote C-, A-, and D-genome specific repeats, respectively; blue-green gradient characters denote A + D-genome specific repeats, and black characters denote FISH probes labelling C-, A- and D-genomes. Ab, A. brevis; Ah, A. hirtula; Ast, A. strigosa; As, A. sativa. T, tandem; R, retrotransposon. ●: retroelement; ▲: tandem repeat verified by bioinformatics; ▼: tandem repeats verified by in situ hybridization; NCBI blast results of tandem repeat families see Additional files 22: Table S10Back to article page
