Additional file 16: Fig. S2. Synteny and collinearity between linkage groups 8 and 10 amongst the Pinus radiata parental linkage maps in this study. Vertical bars represent linkage groups, horizontal lines within bars show the position of markers within each group, lines between groups indicate homologous markers at the contig level. Scale bars shows cM (Kosambi). Fig. S1A shows perfect synteny and high collinearity between these linkage groups in three parental linkage maps. Fig. S2B shows that linkage group 8 in parent 850,096 has markers from both linkage groups 8 and 10 in parents 268,345 and 268,405. However, all mapped markers in parent 850,096 matched only their homologous chromosome in parent 850,055 (Fig. S1C). The red box in fig. S1b highlights a region of ~ 10 cM, on linkage group 8 in parent 850,096, with a mixture of homologs from linkage groups 8 and 10 as well as very tightly clustered markers.
