Schematic diagram showing postulated intermolecular recombination events across Avena sativa (top) and Taraxacum amplum (bottom). a Gene order and orientation within LSC intermolecular recombination. Roman numeral arrows denote the sequences of recombination events: I, Duplication of trnfM gene; II, Intermolecular recombination of trnC-GCA-trnR-UCU and psbD-trnfM regions; II, Inversion of trnC-GCA-trnE-UUC region. b Gene order and orientation within IRB intermolecular recombination. Roman numeral arrows denote the sequences of recombination events: I, Loss of ycf1 gene; II, Duplication of rps15-ndhH region; III, Inversion of rps15-ndhF region. The vertical dashed lines indicate the rearrangement start-end base position. Gene transcribed in forward and reverse directions are indicated above and below the middle line, respectively
