Schematic overview of syntenically conserved blocks between the date palm genetic map and oil palm chromosome sequences as identified by CIRCOS plot in figure5. Sequence surrounding markers from the date palm genetic map were aligned to oil palm chromosomes and locations reported on the (a) oil palm chromosomes (chr) or (b) date palm linkage groups (LG). Different color codes indicate syntenic blocks between the individual date palm linkage groups and corresponding regions on oil palm chromosomes as identified in CIRCOS Figures 5 and 7. In case of regions on oil palm chromosomes with indication of significant syntenic relationships to more than one distinct oil palm linkage group, split color bars were used. Areas on oil palm chromosomes with no support for any syntenic relation to date palm or showing promiscuous relations are colored in white.
