Comparison of the Chromosome Structures between the Chicken and Three Anserid Species, the Domestic Duck (Anas platyrhynchos), Muscovy Duck (Cairina moschata), and Chinese Goose (Anser cygnoides), and the Delineation of their Karyotype Evolution by Comparative Chromosome Mapping

The Journal of Poultry Science, 2014
To better understand the process of karyotype evolution in Galloanserae (Galliformes and Anseriformes), we performed comparative chromosome painting with chicken chromosome-specific DNA probes and FISH mapping of the 18S-28S ribosomal RNA (rRNA) genes ...

Improving and correcting the contiguity of long-read genome assemblies of three plant species using optical mapping and chromosome conformation capture data.

Genome Research, 2017
Long-read sequencing can overcome the weaknesses of short reads in the assembly of eukaryotic genomes; however, at present additional scaffolding is needed to achieve chromosome-level assemblies.

Impact of a companion and of chromospheric emission on the shape of chromosome maps for globular clusters [PDF]

A&A 635, A52 (2020), 2020
We investigate the role of binaries and chromospheric emission on HST photometry of globular clusters' stars. We quantify their respective effects on the position of stars in the chromosome map, especially among the first population. We computed atmosphere models and synthetic spectra for stars of different chemical compositions, based on isochrones ...

Chromosomal mapping, differential origin and evolution of the S100 gene family

Genetics Selection Evolution, 2008
S100 proteins are calcium-binding proteins, which exist only in vertebrates and which constitute a large protein family. The origin and evolution of the S100 family in vertebrate lineages remain a challenge.

Sugar transporter proteins in Capsicum: identification, characterization, evolution and expression patterns

Biotechnology & Biotechnological Equipment, 2020
Sugar transporter proteins (STPs) play an important role in plant growth and development and stress resistance. Pepper (Capsicum annuum L.) is a significant economic crop and is widely cultivated worldwide.

Bug mapping and fitness testing of chemically synthesized chromosome X

Science, 2017
INTRODUCTION Design and construction of an extensively modified yeast genome is a direct means to interrogate the integrity, comprehensiveness, and accuracy of the knowledge amassed by the yeast community to date. The international synthetic yeast genome

Evaluation of four methods to identify the homozygotic sex chromosome in small populations

BMC Genomics, 2022
Background Whole genomes are commonly assembled into a collection of scaffolds and often lack annotations of autosomes, sex chromosomes, and organelle genomes (i.e., mitochondrial and chloroplast). As these chromosome types differ in effective population

Masked conditional variational autoencoders for chromosome straightening [PDF]

arXiv, 2023
Karyotyping is of importance for detecting chromosomal aberrations in human disease. However, chromosomes easily appear curved in microscopic images, which prevents cytogeneticists from analyzing chromosome types. To address this issue, we propose a framework for chromosome straightening, which comprises a preliminary processing algorithm and a ...

A Robust Framework of Chromosome Straightening with ViT-Patch GAN [PDF]

arXiv, 2022
Chromosomes carry the genetic information of humans. They exhibit non-rigid and non-articulated nature with varying degrees of curvature. Chromosome straightening is an important step for subsequent karyotype construction, pathological diagnosis and cytogenetic map development.

Bacterial chromosome organization by collective dynamics of SMC condensins [PDF]

Miermans CA, Broedersz CP. 2018 Bacterial chromosome organization by collective dynamics of SMC condensins. J. R. Soc. Interface 15: 20180495, 2018
A prominent organizational feature of bacterial chromosomes was revealed by Hi-C experiments, indicating anomalously high contacts between the left and right chromosomal arms. These long-range contacts have been attributed to various nucleoid-associated proteins, including the ATPase SMC condensin.
