Fig. 1: Comparison between the two Rosa chinensis ‘Old Blush’ sequences released in 2018.

On the x-axis, the OBDH_1.0 Angers assembly (accessed from https://iris.angers.inra.fr/obh/) versus, on the y-axis, the RchiOBHm-V2 Lyon/Toulouse assembly (accessed from https://lipm-browsers.toulouse.inra.fr/pub/RchiOBHm-V2/). Blue points represent forward alignments, while red dots represent reverse alignments, with a minimum length of 250 bp. The alignment was performed using MUMmer v3.23¹⁵⁹. Chromosome 3 of the RchiOBHm-V2 assembly is in the orientation of the ICM map of Spiller et al.². The rearrangement at two-thirds of chromosome 3 is around the RoKSN locus⁵
