The Dissection of Expression Quantitative Trait Locus Hotspots [PDF]

Genetics, 2016
AbstractStudies of the genetic loci that contribute to variation in gene expression frequently identify loci with broad effects on gene expression: expression quantitative trait locus hotspots. We describe a set of exploratory graphical methods as well as a formal likelihood-based test for assessing whether a given hotspot is due to one or multiple ...

Identification of stable QTL controlling multiple yield components in a durum × cultivated emmer wheat population under field and greenhouse conditions

G3: Genes, Genomes, Genetics, 2022
Crop yield gains are needed to keep pace with a growing global population and decreasing resources to produce food. Cultivated emmer wheat is a progenitor of durum wheat and a useful source of genetic variation for trait improvement in durum.

Covariance between relatives for a marked quantitative trait locus [PDF]

Genetics Selection Evolution, 1995
Summary - Best linear unbiased prediction (BLUP) can be applied to marker-assisted selection. This application requires computation of the inverse of the conditional covariance matrix (Gof additive effects for the quantitative trait locus (QTL) linked to the marker locus (ML), given marker genotypes.

Quantitative Trait Locus Analysis of Longitudinal Quantitative Trait Data in Complex Pedigrees [PDF]

Genetics, 2005
Abstract There is currently considerable interest in genetic analysis of quantitative traits such as blood pressure and body mass index. Despite the fact that these traits change throughout life they are commonly analyzed only at a single time point.

Detection of QTL for traits related to adaptation to sub-optimal climatic conditions in chickens

Genetics Selection Evolution, 2017
Background Growth traits can be used as indicators of adaptation to sub-optimal conditions. The current study aimed at identifying quantitative trait loci (QTL) that control performance under variable temperature conditions in chickens.

Mapping of Two Major QTLs Controlling Flowering Time in Brassica napus Using a High-Density Genetic Map

Plants, 2022
Research on the flowering habit of rapeseed is important for the selection of varieties adapted to specific ecological environments. Here, quantitative trait loci (QTL) for the days-to-flowering trait were identified using a doubled haploid population of

Deciphering mechanisms underlying the genetic variation of general production and liver quality traits in the overfed mule duck by pQTL analyses

Genetics Selection Evolution, 2017
Background The aim of this study was to analyse the mechanisms that underlie phenotypic quantitative trait loci (QTL) in overfed mule ducks by identifying co-localized proteomic QTL (pQTL).

Variation in seed dormancy quantitative trait loci in Arabidopsis thaliana originating from one site [PDF]

, 2011
A Quantitative Trait Locus (QTL) analysis was performed using two novel Recombinant Inbred Line (RIL) populations, derived from the progeny between two Arabidopsis thaliana genotypes collected at the same site in Kyoto (Japan) crossed with the reference ...

Genetic Analysis of Mitochondrial Sorting from the MSC3 Mosaic Mutant of Cucumber

Journal of the American Society for Horticultural Science, 2021
Cucumber (Cucumis sativus) plants regenerated from cell cultures occasionally possess mosaic (MSC) phenotypes on cotyledons and leaves. Lines MSC3 and MSC16 have distinct MSC phenotypes and originated from plants regenerated from different cell-culture ...

The X Chromosome in Quantitative Trait Locus Mapping [PDF]

Genetics, 2006
AbstractThe X chromosome requires special treatment in the mapping of quantitative trait loci (QTL). However, most QTL mapping methods, and most computer programs for QTL mapping, have focused exclusively on autosomal loci. We describe a method for appropriate treatment of the X chromosome for QTL mapping in experimental crosses.
