Abstract:
The centromere of maize chromosome 4 was previously localized to a 26-cM interval using molecular markers and B-A translocations. The objective of the present study was to refine the placement of the centromere using secondary trisomics. Two independently isolated secondary trisomics (having an isochromosome plus two normal homologs) for 4S were recovered. RFLP analysis of populations segregating for them placed the centromere of chromosome 4 between bnl15.45 and bnl7.20, two RFLP loci that are 5.4-cM apart on the UMC map and 11.5-cM apart on the BNL map.
