Southern-blot analysis of the black cherry
mdl genes. Genomic DNA (10 μg) from an individual tree
was digested with BamHI (B), HincII (H),
or EcoRI (E), electrophoresed on 0.8% agarose gels, and
blotted onto nylon membranes. Subsequently, the blots were hybridized
at high stringency with the consensus or gene-specific probes. DNA
molecular-mass markers are shown on the left.
