The high mutation rate of Mutator stocks of maize is the result of transposition of Mu elements. Most standard stocks of maize contain sequences homologous to Mu elements, yet they show no genetic activity characteristic of Mu transposition. We have determined the sequence, structure, and genomic organization of several Mu-homologous elements from non-Mutator lines. Our results suggest that these elements transposed into their current genomic positions. We discuss the relationship of these endogenous Mu elements to active elements and the role DNA modification may play in their apparent inactivity.
