Map of tobacco chromosome 21, highlighting the region encompassing the VAM and va loci. Anchored scaffolds missing in both VAM and va plants are shown in yellow and those uniquely missing in VAM in red. Infinium markers used by Edwards et al. [25] and aligned to scaffolds are in light green along with their relative distance in cM. Markers described by Bindler et al. [13] are dark green along with their predicted distance in cM. Note that the two marker systems begin at different ends of the chromosome and differ substantially in overall predicted map distance
