Genome-wide maps of chromatin state (heterochromatin H3K9me2 or centromeric histone H3 variant CENP-A/Cnp1) in heterozygous deletion diploid mhf2∆/+ and the meiotic haploid progeny of heterozygous deletion diploid wip1∆/+, mhf1∆/+ and mhf2∆/+.

ABSTRACT: Genome-wide maps of chromatin state (heterochromatin H3K9me2 or centromeric histone H3 variant CENP-A/Cnp1) in heterozygous deletion diploid mhf2∆/+ and the meiotic haploid progeny of heterozygous deletion diploid wip1∆/+, mhf1∆/+ and mhf2∆/+.

Genome-wide maps of chromatin state (heterochromatin H3K9me2 or centromeric histone H3 variant CENP-A/Cnp1) in heterozygous deletion diploid mhf2∆/+ and the meiotic haploid progeny of heterozygous deletion diploid wip1∆/+, mhf1∆/+ and mhf2∆/+.

Project description:We report the high-throughput profiling of histone modification (H3K9me2) or histone variant CNEP-A/Cnp1 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide H3K9me2 or CENP-A/Cnp1 maps of heterozygous deletion diploid mhf2∆/+ and the meiotic haploid progeny of heterozygous deletion diploid wip1∆/+, mhf1∆/+ and mhf2∆/+ in fission yeast. We find that centromere inactivation and neocentromere formation occur independently and postzygotically in single depletion of CENP-T-W-X-S.

Genome-wide maps of histone H3 variant CENP-A/Cnp1 in the meiotic haploid progeny of wip1∆/+, mhf1∆/+ and mhf2∆/+ and genome-wide maps of histone H3 variant CENP-A/Cnp1 in mhf2+ (or mhf2∆) carrying the inactivated Centromere 1 or Centromere 2.

Project description:We report the high-throughput profiling of histone variant CNEP-A/Cnp1 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide CENP-A/Cnp1 maps of the wild type meiotic haploid progeny of heterozygous deletion diploid wip1∆/+, mhf1∆/+ and mhf2∆/+ and CENP-A/Cnp1 maps of mhf2+ carrying the inactivated Centromere 1 or Centromere 2. We find that CENP-A/Cnp1 spreading into the pericentromeric regions in wild type meiotic progeny of heterozygous deletion diploid wip1∆/+, mhf1∆/+ and mhf2∆/+.

Genome-wide maps of chromatin state (centromeric histone H3 variant CENP-A/Cnp1) in clr4∆ and the transformants from the deletion of clr4 in mhf2∆ (cen2_inactive) or mhf2+ (cen1_inactive).

Project description:We report the high-throughput profiling of histone variant CNEP-A/Cnp1 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide CENP-A/Cnp1 maps of clr4∆ and the transformants from the deletion of clr4 in mhf2∆ (cen2_inactive) or mhf2+ (cen1_inactive) in fission yeast. We find that heterochromatin is not required for the induction of centromere inactivation in mhf2∆ and the maintenance of neocentromere in mhf2+.

Genome-wide maps of chromatin state centromeric histone H3 variant CENP-A/Cnp1 in the meiotic progeny from the genetic crossings of mhf2+ (cen1_inactive) × mhf2+ (cen1_active) and mhf2∆ (cen1_inactive) × mhf2+ (cen1_active).

Project description:We report the high-throughput profiling of histone variant CNEP-A/Cnp1 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide CENP-A/Cnp1 maps of the meiotic progeny from the genetic crossings of mhf2+(cen1_inactive) × mhf2+ (cen1_active) and mhf2∆ (cen1_inactive) × mhf2+ (cen1_active) in fission yeast. We find that endogenous Centromere 1 in mhf2+ is converted to the inactivated Centromere 1 by mhf2∆ through genetic crossing. We also find that Cnp1 spreading into the pericentromeric regions occurs in the wild-type progeny of these two genetic crossings.

Genome-wide maps of chromatin state (heterochromatin H3K9me2 or centromeric histone H3 variant CENP-A/Cnp1) in both mhf2∆ and mhf2+ carrying the inactivated Centromere 1 or Centromere 2.

Project description:We report the high-throughput profiling of histone modification (H3K9me2) or histone variant CNEP-A/Cnp1 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide H3K9me2 or CENP-A/Cnp1 maps of both mhf2∆ and mhf2+ carrying the inactivated Centromere 1 or Centromere 2 in fission yeast. We find that neocemtromeres are formed preferably at pericentromeric regions in single depletion of CENP-T-W-X-S.

Strain abundance assay of 4334 Schizosaccharomyces pombe heterozygous deletion mutants grown in rich medium

Project description:Screening for changes in the growth rate of heterozygous deletion diploid strains has been used in budding yeast to identify potentially rate-limiting steps for cellular growth. Using a similar methodology we examined the growth rates in rich medium for 4,334 fission yeast heterozygous deletion diploids.
