Genomic insights into the NPGS intermediate wheatgrass germplasm collection

Leveraging genomic prediction to scan germplasm collection for crop improvement

The objective of this study was to explore the potential of genomic prediction (GP) for soybean resistance against Sclerotinia sclerotiorum (Lib.) de Bary, the causal agent of white mold (WM). A diverse panel of 465 soybean plant introduction accessions was phenotyped for WM resistance in replicated field and greenhouse tests. All plant accessions were previously genotyped using the SoySNP50K B...

Establishment and Optimization of Genomic Selection to Accelerate the Domestication and Improvement of Intermediate Wheatgrass.

Intermediate wheatgrass (IWG) is a perennial species and has edible and nutritious grain and desirable agronomic traits, including large seed size, high grain yield, and biomass. It also has the potential to provide ecosystem services and an economic return to farmers. However, because of its allohexaploidy and self-incompatibility, developing molecular markers for genetic analysis and molecula...

Genomic insights into positive selection.

The traditional way of identifying targets of adaptive evolution has been to study a few loci that one hypothesizes a priori to have been under selection. This approach is complicated because of the confounding effects that population demographic history and selection have on patterns of DNA sequence variation. In principle, multilocus analyses can facilitate robust inferences of selection at i...

Newer Insights into the Prsevention of the Common Cold

Since most colds are self-limiting, symptoms will usually resolve on their own in seven to ten days. For the majority of patients, treatment is symptomatic and targeted at the most bothersome symptoms. Specific nonprescription therapy may relieve cold symptoms but should be used with caution, especially in at-risk patient populations. Patients should monitor for worsening symptoms, and progress...
