Fig. 2. Physical maps of the Cmdm1 locus
A: the Cmdm1 gene was located on the short arm of chromosome 7 between markers c7-3 and c7-206; B: the Cmdm1 gene was preliminarily delimited to the c7-101-c7-132 interval using 210 short internodes F2 individuals; the numerals below the corresponding markers indicate the numbers of recombinants (Rec) identified among F2 plants; C: fine genetic mapping of the Cmdm1 gene based on 780 short internodes F2 individuals; D: physical map of the Cmdm1 region based on the reference sequence and arrows indicated four annotated ORFs in this region
