Mycorrhizal Symbioses And Plant Interactions, Domenico Prisa Apr 2023

Mycorrhizal Symbioses And Plant Interactions, Domenico Prisa

Karbala International Journal of Modern Science

The growing interest in mycorrhizal fungi in agriculture is related to their symbiotic relationships with cultivated plants. Thanks to functional genomics approaches, mycorrhizae and symbioses with host plants have emerged for their fea-tures. Besides improving nutritional supply, plant-fungal interactions increase plants' tolerance to abiotic stresses such as drought, salinity and cold, as well as their resistance to diseases. Recent studies have investigated the interactions between plants and mycorrhizae, however the mechanisms often remain unclear. Indeed, plants in the field are affected by various stresses and results often appear contradictory. This review is aimed at presenting the most relevant studies in …

Ecological Living In Nepali Food Systems: A Synthesis Of Circular Nutrient And Knowledge Flows In The Kathmandu Valley, Kaitlyn Feely Apr 2023

Ecological Living In Nepali Food Systems: A Synthesis Of Circular Nutrient And Knowledge Flows In The Kathmandu Valley, Kaitlyn Feely

Independent Study Project (ISP) Collection

Researching food-systems in Nepal can feel like drinking from a fire hydrant. Sixty-six percent of the population is directly involved in agriculture and a diverse set of ecocultural understandings influence the practice across the country’s landscapes, ranging from the Himalayas to urban centers to southern plains. In the Kathmandu Valley and peripheral hills where I conducted my research, seemingly any spare land was under cultivation, enabled by fertile ground, optimal climate, and market potential. But despite the prevalence of farming in daily life throughout the country, Nepal’s food system is not domestically self-sufficient. A complex web of imports and exports …

Harvest Aids Did Not Advance Maturity Of Non-Shatter Pennycress, Julija A. Cubins, Samantha Wells, Russ W. Gesch, Gregg A. Johnson, Maninder K. Walia, Ratan Chopra, M. David Marks, Rebecca D. Swenson, Katherine Anna Frels

Department of Agronomy and Horticulture: Faculty Publications

Reliance on summer annual crops in the Upper Midwest results in fallow land from late fall through early spring, providing opportunities to integrate winter crops, such as pennycress (Thlapsi arvense L.), onto the landscape. Pennycress agronomics have primarily been studied using unimproved wild-type lines prone to seed shatter, resulting in significant yield loss if not harvested early. However, high plant and seed moisture complicates harvest and seed storage. A new breeding line with a reducedshatter mutation made it possible to use harvest aids to reduce plant moisture without the risk of seed loss. The objectives of this study were …
