Koplin, Rachel L. Peters, Natasha Purington, Anna Nowak-Wegrzyn, Sarah Saf, Hugh A. Sampson, Joost Westerhout, W. Marty Blom, Joseph L. Baumert, Geert F. Houben, Benjamin C. Remington

Department of Food Science and Technology: Faculty Publications

Sesame is classified as a “major” food allergen for which mandatory disclosure is required. Understanding reaction thresholds and how these vary within the allergic population is crucial in providing appropriate dietary advice to patients, providing guidance to the food industry, and informing dosing regimens for oral food challenges (FC). However, the largest data series used to derive a threshold dose-distribution for sesame included blinded challenge data from just 40 individuals.¹ Data from low-dose, open FC can be used to supplement that from blinded FC, reducing uncertainty in estimating threshold dose-distributions for allergenic foods which otherwise lack sufficient data.^{2 …}

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich

Harold W. Manter Laboratory of Parasitology: Library Materials

Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …

Turkish Journal of Agriculture and Forestry

Human body needs sufficient quantity of protein on daily basis for the normal functioning. Dietary protein in sufficient quantity is becoming a key issue for huge population of the world particularly in developing countries. Present investigation aimed to explore the phenotypic variation and to investigate the genomic regions associated with seed protein contents in Turkish common bean germplasm collected from 19 provinces. Field experiments were conducted according to augmented block design at two locations (Bolu and Sivas) for two consecutive years (2017 and 2018). Analysis of variance revealed highly significant environmental effects (p < 0.05) on seed protein contents within environments, while genotype by environment interaction revealed nonsignificant effects. Overall mean protein contents were 36.36%, while Balikesir-3 and Hakkari-38 yielded minimum (31.64%) and maximum (40.70%) protein contents. Among 19 provinces, accessions from Hakkari and Erzincan provinces disclosed maximum and minimum mean protein contents respectively. Scatter plot between seed protein contents and plant height divided the accessions according to their protein contents and plant height. A total of eight stable accessions were selected and can be recommended for future breeding activities. The implemented constellation plot separated the studied germplasm into two populations on the basis of their protein contents. Genotyping by sequencing resulted 7900 DArTseq markers was used for marker-trait association and a total of 11 markers showed significant association for protein contents. During this study, DArT-3365703 marker was identified in both locations (Sivas and Bolu) during 2017 and might be used for future common bean breeding. Physical map revealed the presence narrow regions between identified markers on Pv02 and Pv05. Therefore, these regions should be considered for future breeding activities. We are confident that results of present study will be helpful for marker-assisted breeding of common bean.
