NUTRIENT INTERACTIONS AND COMPOSITIONAL NUTRIENT DIAGNOSIS NORMS IN PECAN TREE (Carya illinoensis)

The influence of stage of fruit development and plant growth regulators on somatic embryogenesis and the relation of cultivar response on somatic embryogenesis and subsequent plant development have been investigated in eight cultivars of pecan [Carya illinoensis (Wangenh.) C. Koch]. Explants from the micropylar region of the ovule were more embryogenic when removed from fruits in the liquid endosperm stage than were intact ovules from less-mature fruits or from cotyledonary segments of more-mature fruits. Explants conditioned on medium containing auxin alone or auxin + cytokinin produced more somatic embryos than medium containing cytokinin alone. Under the conditions of this study, frequency of embryogenesis, as well as the germination of somatic embryos leading to plant development, indicated appreciable variation among cultivars. Plant development was greatest by far from somatic embryos of `Schley' than other cultivars studied.

Abstract Objectives The purpose of this project was to design, develop and implement an online two-credit course, Drug & Nutrient Interactions, as an elective for a new online Graduate Certificate in Applied Nutrition and Culinary Medicine at the University of Kentucky. Methods Drug & Nutrient Interactions was designed to meet the needs of select student cohorts: undergraduate Pharmacology minors, graduate students enrolled in the Masters in Nutritional Sciences program, and online graduate certificate students. Faculty within the Dept. of Pharmacology and Nutritional Sciences and the Division of Clinical Nutrition were consulted to identify curricular gaps and to avoid redundancy across programs. Instructional designers were consulted to identify evidence-based best practices in online course design and teaching. Results Content of the Drug and Nutrient Interactions course is structured within four thematic modules: 1. Introduction to Pharmacology and Food & Drug Interactions, 2. Exploring Drug-Nutrient Interactions, 3. Genes, Bugs & Time, and 4. Current and Future Directions in Nutrition & Pharmacology. Each module is three to four weeks in duration, to span a 14-week semester. Each week, students’ tasks include reading, watching, writing, and reviewing content related to the student learning objectives. Methods to promote student engagement with the content recur week-to-week, to ensure consistency for students’ experience. An eBook was written by the instructors to provide a current and interdisciplinary review of the intersections of nutritional sciences and pharmacology in the course. In lieu of proctored online exams, module-level assignments assess students’ achievement of learning outcomes. Drug & Nutrient Interactions launched in fall 2019 with nine students enrolling and completing the course. Course analytics track student engagement by logging page views and participation. Increasing students’ page views and participation align with due dates for module assignments. Therefore - in spring 2020, deadlines were shifted to a weekly timeline to foster consistent engagement. Conclusions Instructors should explore various methods to foster student-content, student-student and student-instructor engagement in an online learning environment. Funding Sources This course project was funded by a UK Online award & an Alternative Textbook grant.
