Saturated map of the region containing the ‘ms-h’ locus and candidate genes.

1. Linkage map of ‘ms-h’ with flanking markers on chromosome 9 (Koh et al., 1999).
2. The PAC/BAC contigs encompassing the ms-h gene region.
3. The saturated linkage map of the region containing the ‘ms-h’ locus based on a genetic analysis of the F₂ population (1051 plants). The ms-h gene was flanked by the STS (sequence-tagged site) markers, 5564p and 7596b, at a distance of 0.1 and 0.4 cM, respectively.
4. The grey boxes indicate a total of 11 candidate genes contained in the approximately 60-kb DNA region between two STS markers, 5564p and 7596b. Sequence comparison of candidate genes between the original parent and the mutant revealed a single nucleotide substitution in the ‘UGPase1’ gene. NAM is the abbreviation for No Apical Meristem.
