Genomic variation in maize: Annual and summary report, 1988
We are interested in the molecular basis and biological significance of genomic diversity. Our laboratory has been studying genomic variation in maize and examples of rapidly occurring changes in maize DNA. To understand the mechanisms that generate and maintain variation, the author's lab has followed the reproducibility and stability of new repeated sequence multiplicities in succeeding generations, during plant development and in regenerated plants. We have also initiated studies of the Robertson's Mutator transposon system. These transposons have been shown to be quite variable in copy number in Mutator stocks of maize, but were reported to be absent in normal maize lines. We showed that sequences homologous to the transposon exist in a variety of forms in normal maize, including complete transposon structures. Results are discussed. 3 figs., 1 tab.
