Abstract
We show that the combined action of Isw1 and Chd1 nucleosome-spacing enzymes is required to maintain this organization. In the absence of these enzymes, regular positioning of the majority of nucleosomes is lost. Exceptions include the region upstream of the promoter, the +1 nucleosome, and a subset...

Abstract
We examined the effects of aneuploidy on genomic stability. We analyzed 13 budding yeast strains that carry extra copies of single chromosomes and found that all aneuploid strains exhibited one or more forms of genomic instability. Most strains displayed increased chromosome loss and mitotic recombi...

Abstract
We have biochemically reconstituted two distinct populations of nucleosomes containing Saccharomyces cerevisiae CenH3 (Cse4). Reconstitution of octameric nucleosomes containing histones Cse4/H4/H2A/H2B is robust on noncentromere DNA, but inefficient on AT-rich centromere DNA. However, nonhistone Scm...

Abstract
We applied one of the most sensitive and rapid diagnostic screening method so far developed, called High-Resolution Melting Analysis (HRMA), to detect D. pinea in Austrian pine (Pinus nigra). HRMA exploits differences in the melting behaviour of PCR products to rapidly identify DNA sequence variants...

Abstract
We report here a role for Cohibin at telomeres and show that functions of the complex at chromosome ends and rDNA maintain replicative life span. Cohibin binds LEM/SUN domain-containing nuclear envelope proteins and telomere-associated factors. Disruption of Cohibin or the envelope proteins abrogate...

Abstract
We address these issues by purifying and defining the DNA-binding activity of Smc5. We show that Smc5 binds strongly and specifically to single-stranded DNA (ssDNA). Remarkably, this DNA-binding activity is independent of Smc6 and is observed with the monomeric form of Smc5. We further show that Smc...

Abstract
We have analyzed 200 isolates from different fields using nine simple-sequence repeat (SSR) markers. Forty-nine alleles were detected among the nine SSR loci and isolates from all four Nordic countries shared the most common alleles across the loci. In total 169 multilocus genotypes (based on seven...

Integration of clustering and biclustering procedures for analysis of large DNA microarray datasets.
Abstract
In this paper, a new biclustering method is introduced based on a geometric method. The Hough Transform (HT) in column-pair space is used to find sub-biclusters and the k-means method is used to optimise the combining process. The experiment results show that the K-means Based Geomet...

Abstract
DNA sequencing has revolutionized yeast taxonomy. Although initially rDNA sequences proved to be universal and convenient for assigning phylogenetic relationships, it was eventually supplanted by multigene analysis, which provided more discriminating and robust results. This led to a...

Abstract
We suggest that decreased stability of Tra1-L3733A accounts for the phenotypes since intragenic suppressors of tra1-L3733A restored Tra1 levels, and reducing wild-type Tra1 led to comparable growth defects. Also supporting a key role for the FATC domain in the structure/function of Tra1, addition of...
