Fig. 3From: Extensive genomic rearrangements mediated by repetitive sequences in plastomes of Medicago and its relativesRelationships between repetitive sequences and plastome structural variations. a The overall repeat content shows significant positive correlation with the degree of genomic rearrangements (R = 0.77, P < 6.1e-16). b-d Examples of repeat-mediated tRNA duplicate, inversion and intron gain. The gained intron is constituted mostly by repeats (red)Back to article page
