Genome-wide association mapping of temperature response in agronomically important traits of soybean
… and plant development under temperature stress. Genome-wide association study (GWAS) using high-density and high-quality single nucleotide polymorphisms (SNPs) is a powerful tool to associate markers and important traits. The aims of this study are: 1) to characterize the effects of low and high …

Genomic Selection, Quantitative Trait Loci and Genome-Wide Association Mapping for Spring Bread Wheat (Triticum aestivum L.) Improvement
… traits in plants are linkage analysis and association mapping. These methods are used to identify markers associated with quantitative trait loci (QTL) that underlie trait variation, which are used for marker assisted selection (MAS). Marker assisted selection has been successful to improve …

Fine mapping of the protein QTL cqSeed protein-001 from PI 407788A and genome-wide association mapping in the soyNAM populations using DNA cytosine methylation
… be improved without sacrificing yield. The fine mapping and further characterization of the QTL cqSeed protein-001, an important QTL that impacts protein and oil concentration, can facilitate such improvement in soybean. In addition, the contribution of epigenetic variation to phenotypic …

Evaluation of soybean cyst nematode (SCN) resistance in perennial glycine species and genome-wide association mapping and genomic prediction study for SCN resistance in common bean and prediction of the short distance movement of soybean rust urediniospores through machine learning
… nematode (SCN; Heterodera glycines; HG) is a widely occurring and damaging pathogen with a wide host range. SCN is the leading cause of soybean yield loss in the US and it will likely become a major yield-limiting threat to common bean (Phaseolus vulgaris L.), another highly susceptible host …

Genetic Regulation of Intrinsic Endurance Exercise Capacity in Mice
… capacity in 34 strains of inbred mice using genome-wide association mapping. 2) The effect of chromosome substitution on endurance exercise capacity using linkage analysis in F2 mice. 3) The effect of chromosome substitution on endurance exercise capacity using wild-derived mice. The main …

Genetic Analysis of Nitrogen Remobilization and Kernel Compositon in Zea Mays L. and Sorghum Bicolor (L.) Moench
… Utilizing a diversity panel of over 2,400 lines, genome wide association mapping was conducted in 2012 and 2013 to examine leaf chlorophyll content at different growth stages and kernel composition at maturity. Chlorophyll content meters were utilized for measurements of leaf chlorophyll content …

High-Throughput Phenotyping and Genomic Prediction in Multi-Environment Plant Breeding Field Trials
… hexaploid wheat (Triticum aestivum L.) nested-association mapping population consisting of 1160 recombinant inbred lines was evaluated in yield trials conducted at three locations during the 2020 and 2021 growing seasons. UAV-based multispectral imaging was conducted at 10-15 timepoints …

Evaluations of soybean genotypes for drought tolerance and charcoal rot resistance
Soybean is the fourth most cultivated crop worldwide and provides one of the most important sources of oil and protein. Drought stress is one of the major constraints to soybean yield in the United States. Charcoal rot of soybean, caused by Macrophomina phaseolina, is a soil-borne fungal pathogen …

Dissecting key biomass and adaptation traits of Miscanthus through genetic mapping, exploring mechanisms of cold tolerance, and flowering time in Miscanthus and Saccharum
… We confirmed for the first time a whole-genome duplication in M. sacchariflorus relative to Sorghum bicolor, similar to that observed previously for M. sinensis. Four quantitative trait locus (QTL) analysis methods for detecting marker-trait associations were compared: 1) individual …

An investigation of the mechanism of PAX7 mediated oncogenesis via in silico and in vitro biology
… by a combination of gene duplication and / or genome duplication events over a long period of evolutionary time. The highly conserved paired box sequence within the Pax genes encodes a paired DNA binding domain, indicating that the Pax proteins are transcription factors which bind and regulate …

Mapping of brown stem rot resistance, genetic yield gains, and yield impact of soybean cyst nematode
Fine Mapping of Resistance Genes from Five Brown Stem Rot Resistance Sources in Soybean Brown stem rot (BSR) of soybean [Glycine max (L.) Merr.] caused by Cadophora gregata (Allington & D.W. Chamb.) T.C. Harr. & McNew, can be controlled effectively with genetic host resistance. Three BSR resistance …

SNP ANALYSIS FOR DROUGHT-RELATED CANDIDATE GENES IN A GERMPLASM COLLECTION AND A TILLING POPULATION OF ITALIAN RICE
… the plant to cope with water deficits. The first Genome-Wide Association study on root traits was then performed on a germplasm collection including local accessions representing the genetic diversity of rice cultivated in Italy and a set of foreign varieties from temperate areas adapted to …
