Figure 1.
The circular plastid genome map of M. truncatula Jemalong 2HA line created using the OrganellarGenomeDRAW program.23 Genes shown on the outside of the circle are transcribed in the clockwise direction, and those shown in the inside are transcribed in the counterclockwise direction. Black arrows No. 1 and 2 outside the circle point to the inversion breakpoints in the rps15-ycf1 and rpl20-rps18 intergenic regions. Gene order in the R108 ptDNA between the arrows is in the reverse orientation. Below the map are shown the alignments of imperfect repeat sequences flanking the run of thymidine nucleotides (highlighted in yellow) containing the inversion endpoints in the R108 ptDNA and cognate sequences in 2HA.
