Identification of a 4A/7R and a 7B/4R wheat-rye chromosome translocation
1Institut für Pflanzenbau und Pflanzenzüchtung, Technische Universität München, Freising-Weihenstephan, Federal Republic of Germany.
Abstract:
By producing chromosome substitutions with 'Imperial rye' chromosomes 4R (C) and 7R (D) in the wheat cultivar 'Chinese Spring' two spontaneous translocation lines were obtained. One involves segments of wheat chromosome 4A and rye chromosome 7R, the other involves portions of wheat chromosome 7B and rye chromosome 4R.

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
