Graphical representation of the synteny observed in the Triticum turgidum, the (lo) durum and the Aegilops longissima mitochondrial genomes based on gene localization. Pairs of genes found together in all lines a, b, c, d and gene blocks (I -VII) are shown. Black line in the Ae. longissima indicates the position of border between the two contigs that could not be merged by de novo assembly. Genes labeled as green are present only in one copy in the (lo) durum and the Ae. longissima, blue are missing from either the Ae. longissima or the (lo) durum and gene labeled in red are not present in our final assembly of the (lo) durum line.
