Duplicate Loci

The progenitor diploid genomes (A and C) of the amphidiploid Brassica napus are extensively duplicated with 73% of genomic clones detecting two or more duplicate sequences within each of the diploid genomes. This comprehensive duplication of loci is to be expected in a species that has evolved through a polyploid ancestor. The majority of the duplicate loci within each of the diploid genomes were found in distinct linkage groups as collinear blocks of linked loci, some of which had undergone a variety of rearrangements subsequent to duplication, including inversions and translocations. A number of identical rearrangements were observed in the two diploid genomes, suggesting they had occurred before the divergence of the two species. A number of linkage groups displayed an organization consistent with centric fusion and (or) fission, suggesting this mechanism may have played a role in the evolution of Brassica genomes. For almost every genetically mapped locus detected in the A genome a homologous locus was found in the C genome; the collinear arrangement of these homologous markers allowed the primary regions of homoeology between the two genomes to be identified. At least 16 gross chromosomal rearrangements differentiated the two diploid genomes during their divergence from a common ancestor.Key words: genome evolution, Brassicaeae, polyploidy, homoeologous linkage groups.

Hybrid Clones

Fibroblast cultures prepared from mice homozygous for a Robertsonian translocation (centric fusion) between autosomes 8 and 17 [Rb(8.17)] were used as donors in microcell-mediated chromosome transfer experiments. By using hamster recipient cells deficient in adenine phosphoribosyltransferase (APRT-) and selecting for expression of murine APRT (a chromosome 8 marker), microcell hybrids were isolated which retained only the mouse Rb(8.17) translocation in addition to the hamster chromosome complement. The translocation was stable in cells maintained under APRT+ selective pressure, and mouse marker traits encoded by genes on both chromosomes 8 and 17 segregated concordantly. A second family of hybrid clones was constructed by fusing microcells derived from wild-type mouse fibroblasts with APRT- hamster cells. Four of six clones analyzed retained only mouse chromosome 8. These studies demonstrated that microcell hybrids containing specific Robertsonian translocations as the only donor-derived genetic material can be obtained. Furthermore, a number of Robertsonian translocations between chromosomes which carry selectable markers (chromosomes 3, 8, and 11) and other autosomes have been described. By using fibroblast cultures prepared from mice containing these translocations as donors in microcell fusions, 18 of the 20 mouse chromosomes could be selectively fixed in different hybrid clones. Thus, a collection of 20 hybrid clones, each containing a single, specific mouse chromosome, can be constructed by using the strategy described in this report. The potential utility of such a monochromosomal hybrid panel is discussed.
