Testing new genetic and genomic approaches for trait mapping and prediction in wheat (Triticum aestivum) and rice (Oryza spp)
… They have also supported the use of novel mapping approaches, including Multi-parent Advanced Generation Inter-Cross (MAGIC) populations which have increased precision in identifying markers to inform plant breeding practices. In the first part of this thesis, a high density physical map …

Construction and analysis of the pangenome of Cucurbita moschata to uncover variants associated with virus resistance
… (MAS). This study aims to identify quantitative trait loci (QTLs) associated with MWMV resistance in butternut using a pangenome-assisted bulk segregant analysis (BSAseq) approach. To achieve this, a pangenome of C. moschata was first constructed using an iterative mapping and assembly strategy …

The Genomic Basis of Heterosis in High-Yielding Triploid Hybrids of Willow (Salix spp.) Bioenergy Crops
… triploid, and tetraploid families for a suite of traits important for biomass production, 2) to identify genomic regions linked to these traits, 3) to investigate the patterns gene expression in diploid and triploid hybrids, and 4) to correlate heterosis with gene expression in triploid hybrids. …

Fine mapping studies of quantitative trait loci for baseline platelet count in mice and humans
Platelet count is a complex trait with a substantial genetic contribution. Platelets have a fundamental role in normal haemostasis, with both increases and decreases of the platelet count associated with significant mortality and morbidity. Despite the significant genetic component contributing to …

New Score Tests for Genetic Linkage Analysis in a Likelihood Framework
… has been the successful primary tool for mapping many Mendelian traits and some complex traits until the genetic analysis paradigm shifted from rare Mendelian disease mapping using family data to the common variant-common disease mapping mainly using unrelated case-control data, i.e., …

Navigating through the uncertainty of genotyping-by-sequencing data in polyploids
… of uncertainty within GBS data increases making trait mapping difficult. Furthermore, variant and genotype calling methods remain a challenge for both recent and ancient allopolyploids (e.g. wheat, maize, soybean, Miscanthus), particularly where the reference genome contains highly similar …

Genetic Effects Mediated Through Epistatic Networks Onto Metabolic Traits
Predicting variation in complex traits from DNA sequence is a major public health goal, but our understanding of the genotype-to-phenotype relationship is incomplete. It will remain so unless we can adequately integrate genetic, epigenetic, and environmental information into a systems level …

Analysis of two single trait loci affecting flavonol glycoside accumulations in Arabidopsis thaliana natural variations
… to identify genomic variations causing observed traits. The work presented in this thesis is focused on the identification of new genes involved in accumulation of flavonoid derivatives in A. thaliana wildtype accessions using both metabolomics and genomic approaches. Three different analytical …

Polimorfisme gen apolipoprotein E pada pasien infark miokard akut (IMA) di Rumah Sakit dr. Saiful Anwar Malang
INDONESIA: Apolipoprotein E (Apo E) memiliki peran yang penting dalam metabolisme lipid dalam plasma. Kadar lipid sangat dipengaruhi oleh polimorfisme gen Apo E. Apo E terdiri dari tiga macam alel, yaitu ε2, ε3, and ε4 yang membentuk 6 genotip E2/E2, E3/E3, E4/E4, E4/E2, E4/E3, dan E3/E2. Sehingga …

Investigating the Genetic, Evolutionary, and Functional Mechanisms of Adaptations to Copper Mine Tailings in Mimulus guttatus
<p>The evolution of copper tolerance in the common yellow monkeyflower, Mimulus guttatus, is a classic example of rapid adaptation in plants; however, little is yet known about the genetic, functional, and evolutionary mechanisms involved. How does excess copper cause toxicity in M. guttatus, and …
