Fine mapping of cucumber downy mildew resistance loci identifies candidate genes linked to ethylene‐associated stomatal defence

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Downy mildew, caused by Pseudoperonospora cubensis, is one of the most destructive diseases affecting cucumber and remains difficult to manage sustainably through fungicide‐dependent control strategies. Although several resistance loci have been reported, many previously mapped regions remain too broad for efficient marker‐assisted ...

A critical evaluation of the effect of population size and phenotypic measurement on QTL detection and localization using a large F2 murine mapping population

Genetics and Molecular Biology, 2006
Population size and phenotypic measurement are two key factors determining the detection power of quantitative trait loci (QTL) mapping. We evaluated how these two controllable factors quantitatively affect the detection of QTL and their localization ...

Cross‐Cohort Evidence Links KCNJ6 rs702859 to Impulsive–Compulsive Phenotypes in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Impulse control disorders (ICDs) and related compulsive behaviors (CBs) are frequent non‐motor complications of Parkinson's disease (PD) with a probable genetic contribution. Objective To investigate whether genetic variants involved in reward and punishment processing are associated with impulsive–compulsive phenotypes in PD ...

A simulation study on the accuracy of position and effect estimates of linked QTL and their asymptotic standard deviations using multiple interval mapping in an F₂ scheme

Genetics Selection Evolution, 2004
Approaches like multiple interval mapping using a multiple-QTL model for simultaneously mapping QTL can aid the identification of multiple QTL, improve the precision of estimating QTL positions and effects, and are able to identify patterns and ...

Impact of plant breeding on the responsiveness of maize and wheat varieties to an arbuscular mycorrhizal fungal symbiont

PLANTS, PEOPLE, PLANET, EarlyView.
Field inoculation with arbuscular mycorrhizal fungi (AMF) offers a promising route to improve sustainable agriculture and food production, yet results are often variable. We investigated the mycorrhizal growth response of maize and wheat varieties recommended for farmers and found substantial variation under greenhouse conditions.

PEMETAAN QUANTITATIVE TRAIT LOCI UNTUK SIFAT BERSKALA KATEGORIK

Jurnal Ilmu Pertanian Indonesia, 2007
Genes or regions on chromosome underlying a quantitative trait are called quantitative trait loci (QTL). Characterizing genes controlling quantitative trait on their position in chromosome and their effect on trait is through a process called QTL mapping.

Carbon sequestration strategies for climate resilience: Sorghum‐based innovations for sustainable agriculture in dryland regions

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is intensifying heat, drought, and food insecurity, threatening dryland farming and carbon management worldwide. We reviewed research on sorghum, a drought‐adapted C4 crop, covering physiology, roots, biomass allocation, soil carbon, bioenergy, breeding, phenotyping, management, and policy.

Estimating genomic breeding values and detecting QTL using univariate and bivariate models [PDF]

, 2011
Background Genomic selection is particularly beneficial for difficult or expensive to measure traits. Since multi-trait selection is an important tool to deal with such cases, an important question is what the added value is of multi-trait genomic ...

Haplotypic QTL mapping in an outbred pedigree

Genetical Research, 2003
An offspring genome can be viewed as a mosaic of chromosomal segments or haplotypes contributed by multiple founders in any quantitative trait locus (QTL) detection study but tracing these is especially complex to achieve for outbred pedigrees. QTL haplotypes can be traced from offspring back to individual founders in outbred pedigrees by combining ...

Identifying resistance‐conferring cytochrome P450s in weeds: experimental strategies and practical considerations

Pest Management Science, EarlyView.
Identifying resistance‐conferring cytochrome P450s requires integrating weed characterization, gene discovery and functional validation. No single approach is sufficient to distinguish causal resistance genes from herbicide‐metabolizing enzymes. Abstract Cytochrome P450 monooxygenases (P450s) play a pivotal role in metabolic herbicide resistance, yet ...
