Properties of Mutable Alleles Recovered from Mutator Stocks of Zea Mays L.
The study of transposable elements and the highly mutable alleles they create allows recognition of the fluid nature of both prokaryotic and eukaryotic genomes. Mutations at particular alleles have been instrumental in dissecting the spatial and temporal patterns of gene expression in maize (Zea mays L.) and Drosophila. And with the advent of molecular cloning, the mutable alleles containing a particular insertion element can be isolated by virtue of the transposon “tag” they contain. Recently we have begun studying the genetic and molecular properties of mutable alleles derived from maize lines containing Mutator activity. In this paper we review the properties of unstable alleles of maize and the genetic properties of Mutator lines of maize. A new transposable element family has been discovered and isolated from an unstable allele recovered from a Mutator line (Barker, et al., 1984). The molecular properties of this element called Mu-l will be reviewed.
