Both species of Plenodomus were detected in weed populations with P. lingam being the predominant species recovered (95%). The northernmost sample site with black leg was found less than 32 km from the Oregon-Washington border, and southernmost site occurred within 32 km of the Oregon-California border. Chlorotic leaf spot was detected less than 32 km from Oregon-Washington border, whereas the southernmost detection was approximately 164 km from the Oregon-California border. Based on this study, infected crop residues and weed hosts may facilitate persistence and spread of these pathogens.Stem rust, caused by Puccinia graminis, and crown rust, caused by P. coronata, are common rust diseases on cool-season grasses (Karakkat et al. 2018), for which long-distance spore dispersal was recorded in northern US (Harder and Haber 1992). During the summers of 2019 and 2020, severe infection of stem rust and crown rust was observed on > 60% of tall fescue (Festuca arundinacea) germplasm plants in a breeding nursery located at the University of Georgia, Griffin GA. Rust-infected leaves first presented uredinia pustules, then black telia towards the end of the season. The uredinia pustules of stem rust and crown rust were brick-red and, yellow and arranged along the host veins, respectively. The urediniospores were one-celled, round to ovoid and measured from 20.75±2.44 μm (crown rust) to 27±3.60 μm long (stem rust). The teliospores were two-celled and measured from 45.75±10.14 μm (stem rust) to 51.60±4.0 μm long (crown rust) (Leonard et al. 2005; Cummins 1971). Urediniospores of both rusts were collected cological Herbarium (Catalog No. GAM00013162), was discarded as an earlier record of P. coronata var. avenae and could have been misdiagnosed. Linsitinib Due to the fragile integrity of the original infected plant sample as well as the incipient infection, DNA identification was unsuccessful. To our knowledge, this is the first morphological, genetic and taxonomic report of P. graminis and P. coronata var. avenae f. sp. avenae on tall fescue in Georgia, USA.The COVID-19 pandemic caused nearly all colleges and universities to transition in-person courses to an online format. In this study, we explored how the rapid transition to online instruction during the COVID-19 pandemic affected students with disabilities. We interviewed 66 science, technology, engineering, and math (STEM) undergraduates with disabilities at seven large-enrollment institutions during Spring 2020. We probed to what extent students were able to access their existing accommodations, to what extent the online environment required novel accommodations, and what factors prevented students from being properly accommodated in STEM courses. Using inductive coding, we identified that students were unable to access previously established accommodations, such as reduced-distraction testing and note-takers. We also found that the online learning environment presented novel challenges for students with disabilities that may have been lessened with the implementation of accommodations. Finally, we found that instructors making decisions about what accommodations were appropriate for students and disability resource centers neglecting to contact students after the transition to online instruction prevented students from receiving the accommodations that they required in STEM courses during the COVID-19 pandemic. This study illuminates current gaps in the support of students with disabilities and pinpoints ways to make online STEM learning environments more inclusive for students with disabilities.Aim Serological assays for the detection of anti-SARS coronavirus-2 (SARS-CoV-2) antibodies are essential to the response to the global pandemic. A ligand binding-based serological assay was validated for the semiquantitative detection of IgG, IgM, IgA and neutralizing antibodies (nAb) against SARS-CoV-2 in serum. Results The assay demonstrated high levels of diagnostic specificity and sensitivity (85-99% for all analytes). Serum IgG, IgM, IgA and nAb correlated positively (R2 = 0.937, R2 = 0.839, R2 = 0.939 and R2 = 0.501, p less then 0.001, respectively) with those measured in dried blood spot samples collected using the hemaPEN® microsampling device (Trajan Scientific and Medical, Victoria, Australia). In vitro SARS-CoV-2 pseudotype neutralization correlated positively with the solid phase nAb signals in convalescent donors (R2 = 0.458, p less then 0.05). Conclusion The assay is applicable in efficacy studies, infection monitoring and postmarketing surveillance following vaccine rollout.Given the expansion of genetics in medicine, there is a growing need to develop approaches to engage patients in understanding how genetics affects their health. Various qualitative methods have been applied to gain a deeper understanding of patient perspectives in topics related to genetics. Community dialogues (CD) are a bi-directional research method that invites community members to discuss a pertinent, challenging topic over the course of a multi-week period and the community members openly discuss their positions on the topic. Authors discuss the first application of the CD method to the topic of pharmacogenetics testing. Additional CD are needed to engage diverse participant populations on this topic to improve genetics literacy, enhance physician engagement and drive policy change.Nutrition and mental health – how findings from genetic studies can support the identification of dietary effects Abstract. Introduction Numerous studies indicate that dietary interventions could be an important approach to the prevention and treatment of mental disorders. However, conventional nutritional epidemiological approaches (e. g., observational studies and randomized controlled trials, RCTs) have specific limitations to consider when interpreting the results. This article examines whether genetic studies could help to establish a link between diet and the prevention of mental disorders. Furthermore, it examines whether it is possible to draw conclusions about causal relationships. Methods This narrative review describes various approaches of genetic cross-phenotype studies and presents examples of their applications in nutritional psychiatry. In addition, it discusses specific requirements as well as the strengths and limitations of the respective approaches. Results To date, in the context of nutritional psychiatry, genetic correlation analyses, look-up analyses, and Mendelian randomization (MR) studies have been used for genetic crossphenotype analyses.
