In plant species, construction of framework linkage maps to facilitate quantitative trait loci mapping and molecular breeding has been confined to experimental mapping populations. However, development and evaluation of these populations is detached from breeding efforts for cultivar development. In this study, we demonstrate that dense and reliable linkage(More)
Prairie cordgrass (Spartina pectinata Bosc ex Link) is an indigenous, perennial grass of North America that is being developed into a cellulosic biomass crop suitable for biofuel production. Limited research has been performed into the breeding of prairie cordgrass; this research details an initial investigation into the development of a breeding program(More)
Pyramiding QTL from multiple sources for FHB resistance presents an opportunity to enhance the FHB resistance of elite wheat germplasm. Mapping FHB resistance QTL directly in wheat breeding populations would eliminate the need for purpose-built mapping populations and thus accelerate marker-assisted pyramiding efforts. In this study, we demonstrate that(More)
Single nucleotide polymorphisms (SNPs) are one of the most abundant DNA variants found in plant genomes and are highly efficient when comparing genome and transcriptome sequences. SNP marker analysis can be used to analyze genetic diversity, create genetic maps, and utilize marker-assisted selection breeding in many crop species. In order to utilize these(More)
Since its identification in the late 1990s, the stem rust pathogen (Puccinia graminis. f. sp. tritici (Pgt)) strain Ug99 (race TTKSK) has represented a worldwide wheat production threat due to its ability to overcome most of the resistance genes present in commercial cultivars. In order to address this challenge, resistance genes in wheat cultivars as well(More)
Senescence in biofuel grasses is a critical issue because early senescence decreases potential biomass production by limiting aerial growth and development. 2-Dimensional, differential in-gel electrophoresis (2D-DIGE) followed by mass spectrometry of selected protein spots was used to evaluate differences between leaf proteomes of early (ES)- and late-(More)
Bacterial leaf streak (BLS; caused by Xanthomonas campestris pv. translucens) has become a serious disease of wheat (Triticum aestivum) in the Midwest USA. This study was conducted to map quantitative trait loci (QTL) controlling resistance to BLS in spring wheat using an identity by descent (IBD) mapping approach. The mapping population consisted of 825(More)
Pyramiding QTL for FHB resistance from multiple sources presents an opportunity to enhance the Fhb1 derived resistance of elite spring wheat germplasm. Conventionally, pyramiding QTL using a marker assisted-selection approach requires preliminary mapping studies to identify the resistance QTL from each parental line and validation studies to assess the QTL(More)
