Analysis of the primary sources of quantitative adult plant resistance to stripe rust in US soft red winter wheat germplasm

PLANT GENOME, 14(1).

By: B. Ward*, K. Merrill n, P. Bulli *, M. Pumphrey *, R. Mason*, M. Mergoum *, J. Johnson*, S. Sapkota * ...

MeSH headings : Chromosome Mapping; Disease Resistance / genetics; Genome-Wide Association Study; Plant Breeding; Plant Diseases / genetics; Polymorphism, Single Nucleotide; Quantitative Trait Loci; Triticum / genetics; United States
TL;DR: Relatively few lines carry resistance alleles at all three loci, suggesting that there is a pre‐existing reservoir of enhanced stripe rust resistance that may be further exploited by regional breeding programs. (via Semantic Scholar)

Mapping of a novel major effect Hessian fly field partial-resistance locus in southern soft red winter wheat line LA03136E71

Winn, Z. J., Acharya, R., Merrill, K., Lyerly, J., Brown-Guedira, G., Cambron, S., … Murphy, J. P. (2021, August 10). THEORETICAL AND APPLIED GENETICS, Vol. 8.

By: Z. Winn n, R. Acharya n, K. Merrill n, J. Lyerly n, G. Brown-Guedira n , S. Cambron*, S. Harrison*, D. Reisig n , J. Murphy n

MeSH headings : Animals; Chromosome Mapping; Diptera; Genetic Linkage; Genotype; Herbivory; Larva; Models, Genetic; North Carolina; Phenotype; Plant Breeding; Quantitative Trait Loci; Triticum / genetics
TL;DR: It is shown that field resistance is evident and controlled by a single locus on chromosome 7D, and a novel Hessian fly partial-resistance QTL is termed QHft.nc-7D. (via Semantic Scholar)

Genome-Wide Association Mapping of Fusarium Head Blight Resistance in Wheat using Genotyping-by-Sequencing

PLANT GENOME, 9(1).

By: M. Arruda*, P. Brown *, G. Brown-Guedira*, A. Krill*, C. Thurber*, K. Merrill n, B. Foresman*, F. Kolb*

MeSH headings : Disease Resistance / genetics; Fusarium / physiology; Genome-Wide Association Study; Genotype; Genotyping Techniques; Plant Diseases / genetics; Quantitative Trait Loci; Triticum / genetics; Triticum / microbiology
TL;DR: This is one of the first GWAS using genomic resources from the International Wheat Genome Sequencing Consortium (IWGSC) and can now be used for creating new breeding lines with different combinations of favorable alleles. (via Semantic Scholar)

The Ghost of Outcrossing Past in Downy Brome, an Inbreeding Annual Grass

JOURNAL OF HEREDITY, 104(4), 476–490.

By: S. Meyer  n, S. Ghimire  n, S. Decker n, K. Merrill n & C. Coleman  n

author keywords: Bromus tectorum; cheatgrass; cleistogamy; selfing breeding system; single nucleotide polymorphic marker
MeSH headings : Bromus / genetics; Crosses, Genetic; Gardening; Genotype; Inbreeding / statistics & numerical data; Inheritance Patterns / genetics; Inheritance Patterns / physiology; Microsatellite Repeats / genetics; Phylogeny; Poaceae / genetics; Pollination / genetics; Pollination / physiology; Polymorphism, Single Nucleotide / physiology; Seasons; Self-Fertilization / genetics; Self-Fertilization / physiology
TL;DR: Strict inbreeding in some lineages within a population with occasional outcrossing in others may be related to positive selection on adaptive syndromes associated with specific inbreeding lineages, or possibly to among-lineage differences in genetic regulation of outCrossing.
