Interchromosomal Effects of Autosomal Translocations on Recombination in DROSOPHILA MELANOGASTER.
ETEROZYGOUS autosomal translocations have been shown to affect recomHbination in the X chromosome in various ways (HINTON 1965); translocations with long interstitial distances increased recombination in X, those with short interstitial distances decreased recombination in X, and those with intermediate interstitial distances had little or no effect. Other incidental tests of translocation hete...
متن کاملInterchromosomal Effects on Somatic Recombination in Drosophila Melanogaster.
RECOMBINATION in somatic cells of Drosophila is influenced by various genetic and environmental factors that also affect meiotic recombination. Thus, the amount of somatic crossing over in a given chromosome is controlled by the genetic contents of the chromosomal set (WEAVER 1960) and by the presence of various genes (STERN 1936; KAPLAN 1953). It may also be affected by changes in temperature ...
متن کاملInterchromosomal recombination in Zea mays.
A new allele of the 27-kD zein locus in maize has been generated by interchromosomal recombination between chromosomes of two different inbred lines. A continuous patch of at least 11,817 bp of inbred W64A, containing the previously characterized Ra allele of the 27-kD zein gene, has been inserted into the genome of A188 by a single crossover. While both junction sequences are conserved, sequen...
متن کاملThe Saccharomyces cerevisiae recombination enhancer biases recombination during interchromosomal mating-type switching but not in interchromosomal homologous recombination.
Haploid Saccharomyces can change mating type through HO-endonuclease cleavage of an expressor locus, MAT, followed by gene conversion using one of two repository loci, HML or HMR, as donor. The mating type of a cell dictates which repository locus is used as donor, with a cells using HML and alpha cells using HMR. This preference is established in part by RE, a locus on the left arm of chromoso...
متن کاملThe effects of mismatch repair and RAD1 genes on interchromosomal crossover recombination in Saccharomyces cerevisiae.
We have previously shown that recombination between 400-bp substrates containing only 4-bp differences, when present in an inverted repeat orientation, is suppressed by >20-fold in wild-type strains of S. cerevisiae. Among the genes involved in this suppression were three genes involved in mismatch repair--MSH2, MSH3, and MSH6--and one in nucleotide excision repair, RAD1. We now report the invo...
