Navigating through the uncertainty of genotyping-by-sequencing data in polyploids
The development of genotyping-by-sequencing (GBS) methods has facilitated genomics studies in non-model species, including polyploids. Variant and genotype calling methods have been established for autopolyploids but for a species with a complex genome, such as sugarcane, the level of uncertainty …

Linkage mapping in prairie cordgrass (Spartina pectinata Link) using genotyping-by-sequencing markers
… in prairie cordgrass are currently hampered by the lack of a linkage map, the lack of a Chloridoid reference genome, and by lack of information on inheritance patterns (disomic versus polysomic). Genotyping-by-sequencing (GBS) was applied to a population of 85 progeny from a reciprocal cross …

Combining genotyping-by-sequencing data sets for GWAS and GWS study for maize root System architecture traits
… and total root length. Our study is singular by combining two SNP (Single Nucleotide Polymorphism) data sets with different genetic backgrounds to access the prediction accuracy within, across and combining the populations or subpopulations on root traits in maize. After quality control, …

ASSOCIATION MAPPING OF GENE REGIONS FOR DROUGHT TOLERANCE AND AGRONOMIC TRAITS IN SORGHUM
… the genetic architecture of these traits by employing a novel multi-parent advanced generation intercross (MAGIC) population. The population was formed from 19 founder lines through ten generations of random mating, aided by genetic male sterility (GMS) system. This was followed by seven …

Population Genetic Structure of Unionid Mussels Across Multiple Gulf Drainages
… management decisions. This study utilized a genotyping by sequencing (GBS) approach to study the genetic structure of three Texas state threatened mussel species of family Unionidae: Pleurobema riddellii (Louisiana Pigtoe), Fusconaia askewi (Texas Pigtoe), and Potamilus amphichaenus (Texas …

Parallel and Nonparallel Patterns of Genetic Co-Differentiation: Evidence for Host Associated Differentiation Among Trophic Levels of the Oak Gall Wasp System
… and the host plant on which it develops. Genotyping-by-sequencing was conducted for 758 Synergus from 35 populations selected to reflect known genomic structure of B. treatae across its host plants and geographic range. Population genomic structure of the inquiline based on 57,664 single …

Population genetics of Michaux's sumac, smooth sumac, and their hybrids
… Pickett, VA (Fort Pickett), and a nearby property, Deepwater. Michaux's sumac requires soil disturbance and fire to maintain healthy populations. Before being added to the endangered species list, 47% of populations were extirpated due to habitat loss, fire suppression, and …

GENOMICS FOR WILD AND MEDICINAL PLANT DIVERSITY STUDIES
… Genetic variation data was obtained with Genotyping-By-Sequencing (GBS). In the second part of the project, in collaboration with Aboca S.p.A. Società Agricola, we set the basis for future studies aimed at improving Aboca’s collection of Althaea officinalis, a medicinal plant used for …

Background-dependent genetic architecture of Fusarium head blight resistance in U.S. hard winter wheat
Fusarium head blight (FHB), caused primarily by Fusarium graminearum, is one of the most destructive diseases of wheat worldwide, causing substantial yield losses and mycotoxin contamination of grain. Deployment of major resistance quantitative trait loci (QTL) through marker-assisted breeding is …

Avoiding trade-off when enhancing Fusarium head blight resistance of barley
… economically important disease of barley caused by mycotoxin-producing Fusarium species. Resistance to FHB is associated with several agronomic traits, particularly height. Taller cultivars are generally more resistant; however increased height is less favourable due to the prospect of lodging, …

Genetic dissection of sorghum height and maturity variation using sorghum converted lines and their exotic progenitors
… partially-isogenic populations were generated by crossing six diverse SC lines to their corresponding exotic progenitor (EP) lines to assess the phenotypic effects of individual introgressions from the temperate-adapted donor. Initial genotyping results revealed one of the six populations …

A sorghum NAC gene is associated with variation in vascular development, biomass properties, and yield potential
… (NILs) were created, and flanking markers and genotyping-by-sequencing (GBS) were applied to BC3 and BC2F2 individuals to reduce the region of interest to a 38 kb interval containing 4 candidate genes. One of these genes is a NAC gene containing a stop codon mutation in the mutant (dd) allele. …
