Autoradiograph of PCR Products Resolved on an Acrylamide Gel Showing an ∼10-bp Ladder.
The positions of primers used to obtain the PCR products from maize lines or plasmid DNA are indicated by horizontal arrows; the composition of multimers represented by the indicated PCR products also is diagrammed. Vertical arrows over some multimers represent Zm3 insertions. Lane 1, Zm3-B2 dimer containing plasmid; lane 2, B79 genomic DNA; lane 3, B73 genomic DNA; lane 4, recombinant inbred DNA from a B73 × Mo17 mapping population. The asterisk indicates that the primer was labeled with 33P.
