Locations of chromosomal proteins in polytene chromosomes.
Proceedings of the National Academy of Sciences, 1976 D1, a nonhistone chromosomal protein rich in both basic and acidic amino acids, has been localized at a limited number of specific loci in polytene chromosomes of Drosophila melanogaster. H2B, a nucleosomal histone, and H1, a nonnucleosomal histone, are both found throughout most chromosomal regions.

Excluded volume effect enhances the homology pairing of model chromosomes [PDF]
arXiv, 2015 To investigate the structural dynamics of the homology pairing of polymers, we mod- eled the scenario of homologous chromosome pairings during meiosis in Schizosaccharomyces pombe, one of the simplest model organisms of eukaryotes. We consider a simple model consist- ing of pairs of homologous polymers with the same structures that are confined in a ...

DNA methylation footprints during soybean domestication and improvement
Genome Biology, 2018 Background In addition to genetic variation, epigenetic variation plays an important role in determining various biological processes. The importance of natural genetic variation to crop domestication and improvement has been widely investigated. However,

Sex chromosome evolution: The classical paradigm and so much beyond [PDF]
arXivSex chromosomes have independently evolved in species with separate sexes in most lineages across the tree of life. However, the well-accepted canonical model of sex chromosome evolution is not universally supported. There is no single trajectory for sex chromosome formation and evolution across the tree of life, suggesting the underlying mechanisms ...

The nuclear kinesin KIF18B promotes 53BP1-mediated DNA double-strand break repair
Cell Reports, 2021 Summary: 53BP1 is recruited to chromatin in the vicinity of DNA double-strand breaks (DSBs). We identify the nuclear kinesin, KIF18B, as a 53BP1-interacting protein and define its role in 53BP1-mediated DSB repair.

On the Order of Gene Distribution on Chromosomes Across the Animal Kingdom [PDF]
arXiv, 2019 Background. The large-scale pattern of distribution of genes on the chromosomes in the known animal genomes is not well characterized. We hypothesized that individual genes will be distributed on chromosomes in a mathematically ordered manner across the animal kingdom. Results.

Cytogenomic evaluation of regenerated Aralia elata using PLOP-FISH and flow cytometry
Scientific ReportsAralia elata is closely related to Panax ginseng and contains high levels of saponins and other medicinal compounds. Successful A. elata micropropagation is commercially significant; however, the genomic stability of tissue culture-derived regenerants is

A survey of chromosome anomalies in Malta [PDF]
, 1989 433 individuals referred for chromosome analysis between 1983 and 1987 were included in the survey. Among individuals with dysmorphic features or congenital anomalies 42% of babies referred in the neonatal period and 12 to 30% of individuals in older age

Motorized Chromosome Models of Mitosis [PDF]
arXivDuring mitosis, near-spherical chromosomes reconfigure into rod-like structures to ensure their accurate segregation to daughter cells. We explore here, the interplay between the nonequilibrium activity of molecular motors in determining the chromosomal organization in mitosis and its characteristic symmetry-breaking events.
