Abstract The transposable element, Tam3, gives rise to large-scale (greater than 1 kb) chromosomal rearrangements at a low frequency, when it is inserted at the nivea locus of Antirrhinum majus. Although some deletions may result from imprecise excision of Tam3, rearrangements involving deletion, dispersion and inverted duplication of flanking sequences, where Tam3 remains in situ, have also been identified. These rearrangements have been mapped at the molecular level, and the behavior of Tam3 following rearrangement has been observed. It is clear that Tam3 has enormous potential to restructure chromosomes through successive rounds of large-scale rearrangements. The mechanisms by which such rearrangements might arise are discussed.

Abstract The transposable element Tam3 of Antirrhinum majus is capable of causing large-scale chromosomal restructuring. It induced a large deletion at the nivea locus, to produce the allele niv-:529. The deletion removed the entire nivea coding region while the element remains intact with the potential to induce further rearrangements. Genetic experiments showed that the endpoint of the deletion (called x) is closely linked to nivea. The DNA sequences of niv-:529, a genomic excision of Tam3 from niv-:529, and the original genomic position of x have been determined. These data suggest that the deletion could have resulted from an abortive transposition or through breakage and religation.
