Fig. 2: Positional cloning of Ms-cd1 on chromosome 9.
From: A natural mutation in the promoter of Ms-cd1 causes dominant male sterility in Brassica oleracea

a Flowers from the parents of the three mapping populations. b Ms-cd1 was mapped to a ~10.9-kb interval between markers K9-31 and K9-39, and allelic variations in this genomic DNA region were evaluated.
