Abstract

There is both genetic and molecular evidence that the maize Suppressor-imitator (Spm) element encodes gene products necessary for transposition and autoregulation (reviewed in Fedoroff, 1983, 1989, Gierl et al., 1989). Identification of the element-encoded gene products that participate in transposition and regulation has been hindered by the pleiotropy of spontaneous mutations in the element and a poor understanding of how the element is regulated. Here we review recent progress in our laboratory in the identification and characterization of element-encoded transcripts, as well as in understanding both positive and negative regulation of Spm activity.
