Sequencing of 15 622 Gene-bearing BACs Clarifies the Gene-dense Regions of the Barley Genome [PDF]

open access: yes, 2015
Barley (Hordeum vulgare L.) possesses a large and highly repetitive genome of 5.1 Gb that has hindered the development of a complete sequence. In 2012, the International Barley Sequencing Consortium released a resource integrating whole-genome shotgun ...

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

Genomic variation within alpha satellite DNA influences centromere location on human chromosomes with metastable epialleles

open access: yesGenome Research, 2016
Alpha satellite is a tandemly organized type of repetitive DNA that comprises 5% of the genome and is found at all human centromeres. A defined number of 171-bp monomers are organized into chromosome-specific higher-order repeats (HORs) that are ...

The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]

open access: yes, 2015
Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

Non‐Invasive Prenatal Testing by Cell‐Free DNA (cfNIPT) for Detecting Turner Syndrome With Mosaicism and Structural Variants—Prenatal Findings and Postnatal Outcomes

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner Syndrome (TS) is a sex chromosomal disorder associated with karyotype heterogeneity. Although TS can be associated with severe prenatal findings, most often linked to the 45, X karyotype, the majority of TS fetuses have no overt phenotype, resulting in delayed diagnosis and management.

A time out for CENP-A

open access: yesMolecular & Cellular Oncology, 2017
Proper chromosome segregation relies on a functional centromere–kinetochore interface. We showed that chromatin containing CENtromere Protein A (CENP-A) is essential for centromere assembly, but dispensable for chromosome segregation in the presence of ...

Centromere location in Arabidopsis is unaltered by extreme divergence in CENH3 protein sequence

open access: yesGenome Research, 2017
During cell division, spindle fibers attach to chromosomes at centromeres. The DNA sequence at regional centromeres is fast evolving with no conserved genetic signature for centromere identity.

Molecular and classical cytogenetic analyses demonstrate an apomorphic reciprocal chromosomal translocation in Gorilla gorilla [PDF]

open access: yes, 1992
The existence of an apomorphic reciprocal chromosomal translocation in the gorilla lineage has been asserted or denied by various cytogeneticists. We employed a new molecular cytogenetic strategy (chromosomal in situ suppression hybridization) combined ...

Comparative analysis of short‐term and long‐term LL‐37‐induced rosacea‐like mouse models: Histopathological features and inflammatory immune responses

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The aim of this study was to improve the long‐term LL‐37 mouse model and compare the disease manifestations and pathophysiology of short‐term and long‐term LL‐37‐induced rosacea‐like models. The results show that the long‐term LL‐37 induced mouse model provides a practical animal model for further study of the pathological mechanism of severe rosacea ...

The budding yeast Centromere DNA Element II wraps a stable Cse4 hemisome in either orientation in vivo

open access: yeseLife, 2014
In budding yeast, a single cenH3 (Cse4) nucleosome occupies the ∼120-bp functional centromere, however conflicting structural models for the particle have been proposed. To resolve this controversy, we have applied H4S47C-anchored cleavage mapping, which
