Refining the linkage map position of cent9, the maize 9 centromere. Integrated linkage (A) and cytogenetic (B) maps showing the new estimated map position (A, hatched box) for the maize 9 centromere are shown. Map units for A are described in the Figure 1 legend. Map units for B are centiMcClintocks, and 9S refers to the short arm and 9L refers to the long arm. (C) Straightened projections of chromosomes showing the representative of each of the centromere-linked markers, pseudocolored as described in Figure 3E.
