Homeologous linkage groups between Q. robur (Q) and C. sativa (C).
Linkage groups were named as in Barreneche et al. (1998) et Casasoli et al. (2001). Oak linkage groups were taken as reference and ordered from Q1 to Q12. Orthologous markers are shown in red. All orthologous markers mapped in this work and previously by Barreneche et al. (2004) were represented. Markers EST2T32, EST2T3, EST1T11, EST2T13 and CsCAT15 were not represented in oak linkage groups because they were mapped in a different mapping population. Marker ESTS08A01 was mapped in the linkage group Q3 but it was not represented because its introduction perturbed marker order. This marker was orthologous to the ESTCons75 mapped in the homeologous linkage group C8. The figure was drawn using MapChart software (Voorrips, 2002).
