Characterization of a highly conserved sequence related to mutator transposable elements in maize.
Mutator stocks of maize exhibit a high mutation rate correlated with the activity of a family of transposable elements. Mu1 and, to a lesser extent, the closely related Mu1.7 elements are responsible for most mutator-induced mutations that have been characterized. These elements are found in 10-60 copies in mutator stocks, and zero to a few intact elements exist in nonmutator maize stocks. Addi...
متن کاملMolecular Model for the Transposition and Replication of Bacteriophage Mu and other
A series of molecular events will explain how genetic elements can transpose from one DNA site to another, generate a short oligonucleotide duplication at both ends of the new insertion site, and replicate in the transposition process. These events include the formation of recombinant molecules which have been postulated to be intermediates in the transposition process. The model explains how t...
متن کاملLetting Escherichia coli teach me about genome engineering.
A career of following unplanned observations has serendipitously led to a deep appreciation of the capacity that bacterial cells have for restructuring their genomes in a biologically responsive manner. Routine characterization of spontaneous mutations in the gal operon guided the discovery that bacteria transpose DNA segments into new genome sites. A failed project to fuse lambda sequences to ...
متن کاملMicroarray analysis of transposition targets in Escherichia coli: the impact of transcription.
Transposable elements have influenced the genetic and physical composition of all modern organisms. Defining how different transposons select target sites is critical for understanding the biochemical mechanism of this type of recombination and the impact of mobile genes on chromosome structure and function. Phage Mu replicates in Gram-negative bacteria using an extremely efficient transpositio...
متن کاملTransposition-mediated DNA re-replication in maize
Every DNA segment in a eukaryotic genome normally replicates once and only once per cell cycle to maintain genome stability. We show here that this restriction can be bypassed through alternative transposition, a transposition reaction that utilizes the termini of two separate, nearby transposable elements (TEs). Our results suggest that alternative transposition during S phase can induce re-re...
