Genomic Southern analysis. About 10 μg of
genomic DNA from cucumber was digested with HincII (lane
1), XbaI (lane 2), NdeI (lane 3),
NcoI (lane 4), HindIII (lane 5), and
EcoRI (lane 6) and then separated on a 0.6% agarose
gel. As a probe, an EcoRI fragment of
lox-1 (A) or an EcoRI 3′-end fragment (B)
was used. A schematic diagram of lox-1 and templates
used for the preparation of probes are shown in C.
