Summary
Genomic clones from a Northern Flint Line of Zea mays are shown to carry a 700 bp insertion, Cin 1. The Cin 1 insert is not present in the homologous, unique DNA fragment of a midwestern maize line. However, Cin 1 is present in multiple copies in both lines.
Restriction enzyme analysis of the cloned DNAs and their corresponding genomic regions suggest that no alterations have occurred during the in vitro cloning procedure.
