Gene conversions and crossing over during homologous and homeologous ectopic recombination in Saccharomyces cerevisiae.
The pma1-105 mutation reduces the activity of the yeast plasma membrane H(+)-ATPase and causes cells to be both low pH and ammonium ion sensitive and resistant to the antibiotic hygromycin B. Revertants that can grow at pH 3.0 and on ammonium-containing plates frequently arise by ectopic recombination between pma1-105 and PMA2, a diverged gene that shares 85% DNA sequence identity with PMA1. Th...
متن کاملSexy gene conversions: locating gene conversions on the X-chromosome
Gene conversion can have a profound impact on both the short- and long-term evolution of genes and genomes. Here, we examined the gene families that are located on the X-chromosomes of human (Homo sapiens), chimpanzee (Pan troglodytes), mouse (Mus musculus) and rat (Rattus norvegicus) for evidence of gene conversion. We identified seven gene families (WD repeat protein family, Ferritin Heavy Ch...
متن کاملCrossing over and Gene Rearrangement in Flowering Plants.
K i n d s of gene rearrangement “ Crossing over” exists apparently in all those flowering plants which have been sufficiently investigated with regard to it. (By itself, it does not rearrange different genes, but only exchanges alleles.) Genetically i t consists in exchange of normally equal and homologous segments of a gene string (MORGAN 1911, STURTEVANT 1915, MULLER 1916). It has been proved...
متن کاملBayesian Population Genomic Inference of Crossing Over and Gene Conversion
Meiotic recombination is a fundamental cellular mechanism in sexually reproducing organisms and its different forms, crossing over and gene conversion both play an important role in shaping genetic variation in populations. Here, we describe a coalescent-based full-likelihood Markov chain Monte Carlo (MCMC) method for jointly estimating the crossing-over, gene-conversion, and mean tract length ...
متن کاملChromosome Structure and Crossing Over.
A major obstacle to understanding classical genetic crossing over in higher organisms has been the lack of sufficient knowledge concerning the structure of chromosomes. Without accurate information, in particular, as to how the hereditary substance (DNA) is built into the chromosome, it may be premature to devise models depicting how that material may be recombined in crossing over. In recent y...
