. Associated with this unusually unstable genome are two structural features potentially involved in the rearrangements . A dispersed family of repeats, with each element about 1 kb in length, is present ...
class of transposons. These transposable elements can affect gene structure and function in several ways: inactivation of the target gene through insertion , diversification of the nucleotide sequence ...
expression upon insertion within or adjacent to a gene, DNA sequence variation through excision and probably extensive chromosomal rearrangements due to recombination between members of a particular family ...
but these were distributed over nine of the 12 tomato chromosomes. Only one Ac insertion was linked to the T‐DNA locus. The structural integrity of these Ac elements was examined and no evidence of deletions ...
by insertion of a given class of Mu elements or by a Mu-induced genomic rearrangement , a possible intragenic insertion site specificity, and the molecular nature of reversion events are all unknown ...
Structural aberrations, their frequency and distribution as well as distribution of the tandem repetitive minisatellite DNA clusters of Alu and Hinf elements and two retroelements, the LINE NLRCth1 ...
-3 gene, accompanied by demethylation of at least one Hpa II site within the Lyt-2 gene. Gene cloning analysis of one mutant demonstrated that the structural rearrangement was due to insertion ...
and SVA elements are the only transposable elements that have unequivocally been shown to be currently active in humans, as shown by de novo insertions that are responsible for genetic disorders ...
of fungal genomes. In most genomic analyses, repetitive sequences are associated with transposable elements (TEs). TEs are dispersed repetitive DNA sequences found in a host genome. These elements have ...
between dispersed copies of a TE can rearrange large genomic segments ( Haack and Roth, 1995 ). These properties make TEs, which occur in nearly all organisms, a major source of genomic plasticity ...
