Induction of instability at selected loci in maize.

The suppressor-mutator system of control of gene action in maize.
In this paper McClintock described a novel mobile genetic element that she called Suppressor-Mutator (Spm), and its complex regulation. She discovered that Spm could switch back and forth between an “inactive&rd…
