Unraveling the Genetic Architecture of Complex Traits in Plants

Acta Biológica Colombiana, 2023
Complex traits are those whose inheritance does not follow simple and predictable patterns. They are not governed by a single locus, instead, they are determined by several loci and are influenced by the environment.

Quantitative trait loci and metabolic pathways [PDF]

Proceedings of the National Academy of Sciences, 1998
The interpretation of quantitative trait locus (QTL) studies is limited by the lack of information on metabolic pathways leading to most economic traits. Inferences about the roles of the underlying genes with a pathway or the nature of their interaction with other loci are generally not possible. An exception is resistance to the corn

Mapping Environment-Specific Quantitative Trait Loci [PDF]

Genetics, 2010
Abstract Environment-specific quantitative trait loci (QTL) refer to QTL that express differently in different environments, a phenomenon called QTL-by-environment (Q × E) interaction. Q × E interaction is a difficult problem extended from traditional QTL mapping.

Interpreting Functional Impact of Genetic Variations by Network QTL for Genotype–Phenotype Association Study

Frontiers in Cell and Developmental Biology, 2022
An enormous challenge in the post-genome era is to annotate and resolve the consequences of genetic variation on diverse phenotypes. The genome-wide association study (GWAS) is a well-known method to identify potential genetic loci for complex traits ...

Quantitative Trait Loci for Murine Growth [PDF]

Genetics, 1996
Abstract Body size is an archetypal quantitative trait with variation due to the segregation of many gene loci, each of relatively minor effect, and the environment. We examine the effects of quantitative trait loci (QTLs) on age-specific body weights and growth in the F2 intercross of the LG/J and SM/J strains of inbred mice.

Genetic regulation of cholesterol absorption and plasma plant sterol levels

Journal of Lipid Research, 2003
The molecular basis of the processes that control two closely related traits, the absorption of cholesterol from the intestines and plasma plant sterol levels, are only partially understood. The discovery that mutations in two novel hemitransporters, ATP

Mapping and Validation of Quantitative Trait Loci for Root Architectural Traits in Rice (Oryza sativa) under Non-Stress and Salinity Stress Conditions

Tropical Agricultural Research, 2018
Root architectural traits are governed by many genes exhibiting polygenic inheritance. The dissection of the genetic basis of root traits could be achieved by mapping of quantitative trait loci (QTLs) using molecular markers.

Mapping quantitative trait loci underlying triploid endosperm traits [PDF]

Heredity, 2003
Endosperm, which is derived from two polar nuclei fusing with one sperm, is a triploid tissue in cereals. Endosperm tissue determines the grain quality of cereals. Improving grain quality is one of the important breeding objectives in cereals. However, current statistical methods for mapping quantitative trait loci (QTL) under diploid genetic control ...

Massively parallel reporter assay confirms regulatory potential of hQTLs and reveals important variants in lupus and other autoimmune diseases

HGG Advances
Summary: We designed a massively parallel reporter assay (MPRA) in an Epstein-Barr virus transformed B cell line to directly characterize the potential for histone post-translational modifications, i.e., histone quantitative trait loci (hQTLs ...

Integration of QTL and bioinformatic tools to identify candidate genes for triglycerides in mice

Journal of Lipid Research, 2011
To identify genetic loci influencing lipid levels, we performed quantitative trait loci (QTL) analysis between inbred mouse strains MRL/MpJ and SM/J, measuring triglyceride levels at 8 weeks of age in F2 mice fed a chow diet.
