DNA methylation of maize transposable elements is correlated with activity
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1990Transposition of the maize transposable elements Ac , Spm and Mu is correlated with a lack of methylation. For both Ac (Schwartz & Dennis 1986) and Spm (Fedoroff et al.

Analysis of the cis-acting DNA elements required for piggyBac transposable element excision
Molecular and General Genetics MGG, 1997The terminal DNA sequence requirements for piggyBac transposable element excision were explored using a plasmid-based assay in transfected, cultured insect cells. A donor plasmid containing duplicate 3' piggyBac terminal inverted repeats was constructed that allowed individual nucleotides or groups of nucleotides within one of the 3' repeats to be ...

Population genetics of transposable DNA elements
1993This paper is an attempt to bring together the various, dispersed data published in the literature on insertion polymorphism of transposable elements from various kinds of populations (natural populations, laboratory strains, isofemale and inbred lines).

DNA Methylation and Transposable Genetic Elements
1984The process of DNA methylation has excited the imagination of many investigators since Gold etal. (1963 a, b) demonstrated an enzyme which transferred methyl groups from S-adenosylmethionine (SAM) to DNA. The feasibility of this process had been indicated by the discovery that a similar transfer was catalyzed in vitro by soluble enzymes from ...

Plant transposable elements generate the DNA sequence diversity needed in evolution
The EMBO Journal, 1985Two germinal and 16 somatic reversion events induced by the Enhancer (En) transposable element system at the wx-8::Spm-I8 allele of Zea mays were cloned and studied by sequence analysis. Excision of the Spm-I8 receptor element from the wx gene results in various mutant DNA sequences.

DNA sequence requirements for hobo transposable element transposition in Drosophila melanogaster
Genetica, 2011We have conducted a structure and functional analysis of the hobo transposable element of Drosophila melanogaster. A minimum of 141 bp of the left (L) end and 65 bp of the right (R) end of the hobo were shown to contain sequences sufficient for transposition.

DNA sequence analysis of a Drosophila foldback transposable element rearrangement
Molecular and General Genetics MGG, 1982The complete nucleotide sequence of a DNA rearrangement associated with the foldback 4 (FB 4) transposable element is presented. The results demonstrate that the entire loop sequence and almost all of one of the inverted terminal repeats is absent.

DNA Methylation and Activity of the Maize Spm Transposable Element
1995Maize transposons were the first plant genes known to undergo reversible heritable inactivation. Early in the study of the Suppressor-mutator (Spm) trans-posable element McClintock recognized that certain isolates of the element either cycled between inactive and active phases during development or underwent an inactivation event of longer duration and

Transposable DNA elements and life history traits
Genetica, 1992As an initial study of the influence of transposable DNA elements on life history traits, and as a model system for estimating the impact of somatic genetic damage on longevity, the effect of P DNA element movement in somatic cells on adult lifespan was measured in Drosophila melanogaster males.
