Genotyping by sequencing allows for large-scale genetic analyses in plant species with no reference genome, but sets the challenge of sound inference in presence of uncertain genotypes. We report an imputation-based genome-wide association study (GWAS) in reed canarygrass (Phalaris arundinacea L., Phalaris caesia Nees), a cool-season grass species with potential as a biofuel crop. Our study inv...

Switchgrass (Panicum virgatum L.) and reed canarygrass (Phalaris arundinacea L.) were pretreated under ambient temperature and pressure with sulfuric acid and calcium hydroxide in separate experiments. Chemical loadings from 0 to 100g (kg DM)(-1) and durations of anaerobic storage from 0 to 180days were investigated by way of a central composite design at two moisture contents (40% or 60% w.b.)...

Potato (Solanum tuberosum) is one of fourmajor food crops in the world. Weed control is a major component in potato production and has been accomplished using different methods, including but not limited to the use of herbicides and straw mulch. A combination of preemergence herbicide and straw mulch may improve weed control; however, no information is available for combining both methods, alon...

Thousands of hectares of timothy (Phleum pretense L.) grown in the Mid-Atlantic region are infected by cereal rust mite (Abacarus hysterix) that causes discoloration and curling of leaves, decreased nutritional quality, and substantial decreases in yield. A decline in production of timothy hay can lower income for hay producers and cause horse owners to search for alternative hays. Low alkaloid...

Biological abatement was used to condition dilute acid-pretreated hydrolysates of three perennial herbaceous crops that are potential bioenergy feedstocks: switchgrass, reed canarygrass, and alfalfa stems. Fungal isolate Coniochaeta ligniaria was inoculated into the hydrolysates to metabolize and remove inhibitory compounds prior to yeast fermentation of glucose. Switchgrass, reed canarygrass, ...

Despite the increasing biological and economic impacts of invasive species, little is known about the evolutionary mechanisms that favor geographic range expansion and evolution of invasiveness in introduced species. Here, we focus on the invasive wetland grass Phalaris arundinacea L. and document the evolutionary consequences that resulted from multiple and uncontrolled introductions into Nort...

Plant breeders have played an essential role in improving agricultural crops, and their efforts will be critical to meet the increasing demand for cellulosic bioenergy feedstocks. However, a major concern is the potential development of novel invasive species that result from breeders' efforts to improve agronomic traits in a crop. We use reed canarygrass as a case study to evaluate the potenti...

forage K concentration was 12 g kg 1 (Brown et al., 1969). Timothy stands should persist over time with a High K grass forage increases risk of animal metabolic disorders, concentration of 15 to 18 g K kg 1 in headed spring and forage management of perennial grass grown under K-limiting soil conditions needs further study. Our objective was to evaluate growth and 12 to 16 g K kg 1 in regrowth, ...
