Association Studies and Legume Synteny Reveal Haplotypes Determining Seed Size in Vigna unguiculata.

Highly specific seed market classes for cowpea and other grain legumes exist because grain is most commonly cooked and consumed whole. Size, shape, color, and texture are critical features of these market classes and breeders target development of cultivars for market acceptance. Resistance to biotic and abiotic stresses that are absent from elite breeding material are often introgressed through crosses to landraces or wild relatives. When crosses are made between parents with different grain quality characteristics, recovery of progeny with acceptable or enhanced grain quality is problematic. Thus genetic markers for grain quality traits can help in pyramiding genes needed for specific market classes. Allelic variation dictating the inheritance of seed size can be tagged and used to assist the selection of large seeded lines. In this work we applied 1,536-plex SNP genotyping and knowledge of legume synteny to characterize regions of the cowpea genome associated with seed size. These marker-trait associations will enable breeders to use marker-based selection approaches to increase the frequency of progeny with large seed. For 804 individuals derived from eight bi-parental populations, QTL analysis was used to identify markers linked to 10 trait determinants. In addition, the population structure of 171 samples from the USDA core collection was identified and incorporated into a genome-wide association study which supported more than half of the trait-associated regions important in the bi-parental populations. Seven of the total 10 QTLs were supported based on synteny to seed size associated regions identified in the related legume soybean. In addition to delivering markers linked to major trait determinants in the context of modern breeding, we provide an analysis of the diversity of the USDA core collection of cowpea to identify genepools, migrants, admixture, and duplicates

Stress, Mindfulness and Occupational Engagement: A Pilot Study of the HOME Protocol

Stress and disengagement from meaningful occupations are barriers graduate students face daily. This mixed methods study aimed to investigate the effectiveness of the nine-minute Huntington Occupational Mindfulness and Engagement (HOME) protocol for occupational therapy (OT) graduate students to re-engage in meaningful occupations. Participants (N=29) were selected through a convenience sample at a Midwestern university’s OT doctoral program and randomly assigned to either an experimental HOME Protocol group or a control journaling group. Students completed the Coping Orientation to Problems (COPE) Inventory and the Perceived Stress Scale (PSS) as pre and post assessments and received training in the assigned protocols. For four weeks, participants utilized their designated protocols at least one time per week. Following data collection, optional focus groups provided insight into participants’ perceived engagement and use of the protocols. Data analyzed through paired t-tests and independent samples t-tests demonstrated significance in the reduction of stress levels (d=-1.595; p\u3c.001) and increased levels of engagement (d=1.106; p=.001) for the experimental group using the HOME Protocol. No significant difference was found between change scores of the experimental and control groups. Qualitative data revealed themes of Habit Formation, Management of Stress and Overwhelming Feelings, and Re-focus for Re-engagement in Activity. Integrated analysis of qualitative and quantitative data supported the HOME Protocol as a beneficial tool for students’ re-engagement in meaningful activities. The pilot study suggested positive benefits for increasing engagement and decreasing stress levels when using the HOME Protocol. Further research is indicated to determine its effectiveness when expanded to other academic programs that allow for a larger, more diverse sample

Titanium Dioxide Nanotubes as Model Systems for Electrosorption Studies

Highly ordered titanium dioxide nanotubes (TiO2 NTs) were fabricated through anodization and tested for their applicability as model electrodes in electrosorption studies. The crystalline structure of the TiO2 NTs was changed without modifying the nanostructure of the surface. Electrosorption capacity, charging rate, and electrochemical active surface area of TiO2 NTs with two different crystalline structures, anatase and amorphous, were investigated via chronoamperometry, cyclic voltammetry, and electrochemical impedance spectroscopy. The highest electrosorption capacities and charging rates were obtained for the anatase TiO2 NTs, largely because anatase TiO2 has a reported higher electrical conductivity and a crystalline structure that can potentially accommodate small ions within. Both electrosorption capacity and charging rate for the ions studied in this work follow the order of Cs+ > Na+ > Li+, regardless of the crystalline structure of the TiO2 NTs. This order reflects the increasing size of the hydrated ion radii of these monovalent ions. Additionally, larger effective electrochemical active surface areas are required for larger ions and lower conductivities. These findings point towards the fact that smaller hydrated-ions experience less steric hindrance and a larger comparative electrostatic force, enabling them to be more effectively electrosorbed
