A saturated genetic linkage map of autotetraploid alfalfa (Medicago sativa L.) developed using genotyping-by-sequencing is highly syntenous with the Medicago truncatula genome. [PDF]

open access: yes, 2014
A genetic linkage map is a valuable tool for quantitative trait locus mapping, map-based gene cloning, comparative mapping, and whole-genome assembly. Alfalfa, one of the most important forage crops in the world, is autotetraploid, allogamous, and highly

Genome-wide mapping reveals single-origin chromosome replication in Leishmania, a eukaryotic microbe [PDF]

open access: yes, 2015
Background DNA replication initiates on defined genome sites, termed origins. Origin usage appears to follow common rules in the eukaryotic organisms examined to date: all chromosomes are replicated from multiple origins, which display variations in ...

Mapping of homoeologous chromosome exchanges influencing quantitative trait variation in Brassica napus

open access: yesPlant Biotechnology Journal, 2017
Summary Genomic rearrangements arising during polyploidization are an important source of genetic and phenotypic variation in the recent allopolyploid crop Brassica napus.

Polytene chromosome map and inversion polymorphism in Drosophila mediopunctata

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Drosophila mediopunctata belongs to the tripunctata group, and is one of the commonest Drosophila species collected in some places in Brazil, especially in the winter. A standard map of the polytene chromosomes is presented.

Epistatic interaction between two nonstructural loci on chromosomes 7 and 3 influences hepatic lipase activity in BSB mice

open access: yesJournal of Lipid Research, 2004
BSB mice exhibit a wide range of obesity despite being produced by a backcross of lean C57BL/6J (B) × lean Mus spretus (SPRET/Pt) F1 animals × B. Previous linkage studies identified a quantitative trait locus (QTL) on mouse chromosome 7 with coincident ...

MaxSSmap: A GPU program for mapping divergent short reads to genomes with the maximum scoring subsequence [PDF]

open access: yes, 2014
Programs based on hash tables and Burrows-Wheeler are very fast for mapping short reads to genomes but have low accuracy in the presence of mismatches and gaps.

A new physical mapping approach refines the sex-determining gene positions on the Silene latifolia Y-chromosome

open access: yesScientific Reports, 2016
Sex chromosomes are particularly interesting regions of the genome for both molecular genetics and evolutionary studies; yet, for most species, we lack basic information, such as the gene order along the chromosome.

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

open access: yesBMC 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

Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

open access: yes, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

Pericentromeric heterochromatin is hierarchically organized and spatially contacts H3K9me2 islands in euchromatin. [PDF]

open access: yes, 2020
Membraneless pericentromeric heterochromatin (PCH) domains play vital roles in chromosome dynamics and genome stability. However, our current understanding of 3D genome organization does not include PCH domains because of technical challenges associated ...
