Cells, 2023 Ubiquitous to normal female human somatic cells, X-chromosome inactivation (XCI) tightly regulates the transcriptional silencing of a single X chromosome from each pair. Some genes escape XCI, including crucial tumour suppressors.

Genomics, 1989 The pericentric region of human chromosome 17 was targeted for specific in situ hybridization of the alphoid DNA subfamily enriched on this chromosome. A recombinant DNA clone containing the entire higher order chromosome 17 alphoid repeat preferentially hybridized to the pericentric region of chromosome 17, but frequently cross-hybridized to other ...

Independent stratum formation on the avian sex chromosomes reveals inter-chromosomal gene conversion and predominance of purifying selection on the w chromosome [PDF]
, 2014 We used a comparative approach spanning three species and 90 million years to study the evolutionary history of the avian sex chromosomes. Using whole transcriptomes, we assembled the largest cross-species dataset of W-linked coding content to date.

Holocentric Chromosomes of Luzula elegans Are Characterized by a Longitudinal Centromere Groove, Chromosome Bending, and a Terminal Nucleolus Organizer Region [PDF]
, 2011 The structure of holocentric chromosomes was analyzed in mitotic cells of Luzula elegans. Light and scanning electron microscopy observations provided evidence for the existence of a longitudinal groove along each sister chromatid.

On the origin of crossover interference : a chromosome oscillatory movement (COM) model [PDF]
, 2011 Background: It is now nearly a century since it was first discovered that crossovers between homologous parental chromosomes, originating at the Prophase stage of Meiosis I, are not randomly placed.

Thermodynamic pathways to genome spatial organization in the cell nucleus [PDF]
, 2009 The architecture of the eukaryotic genome is characterized by a high degree of spatial organization. Chromosomes occupy preferred territories correlated to their state of activity and, yet, displace their genes to interact with remote sites in complex ...

Identification of QTLs associated with cadmium concentration in rice grains
Journal of Integrative Agriculture, 2018 Cadmium (Cd) contamination in rice has been a hot topic of research because of its potential risk to human health. In this study, a double haploid (DH) population derived from Zhongjiazao 17 (YK17) (an early-season indica cultivar)×D50 (a tropical ...

The value of avian genomics to the conservation of wildlife [PDF]
, 2009 Background: Genomic studies in non-domestic avian models, such as the California condor and white-throated sparrow, can lead to more comprehensive conservation plans and provide clues for understanding mechanisms affecting genetic variation, adaptation ...
