Challenges and Opportunities in Managing Diseases in No-Till Farming Systems
Abstract Under NT management, there are several pathogens that often increase, such as Rhizoctonia solani and Fusarium spp., or decrease, such as Gaeumannomyces graminis and Pratylenchus neglectus. While NT farming…
Cap and Adapt: Failsafe policy for the climate emergency
The article explains development of a potential national-level climate policy framework that is capable of quickly eliminating fossil fuels and their emissions, and of accomplishing this with high certainty while…
Sequenced-Based Paternity Analysis to Improve Breeding and Identify Self-Incompatibility Loci in Intermediate Wheatgrass (Thinopyrum intermedium)
Abstract In outcrossing species such as intermediate wheatgrass (IWG, Thinopyrum intermedium), polycrossing is often used to generate novel recombinants through each cycle of selection, but it cannot track pollen-parent pedigrees…
Third-Generation Biomass Crops in the New Era of De Novo Domestication
Abstract The emerging bioeconomy will increase the need for plant biomass. We call for a third-generation of bioenergy crops, or biomass crops, to help move society towards a sustainable bioeconomy…
An Aridamerican model for agriculture in a hotter, water scarce world
Societal Impact Statement Climate change is dramatically restructuring agriculture and damaging crops, food security, and human health, especially in deserts. To radically redesign food systems to buffer against climatic disruptions,…
Cover crop mixture expression is influenced by nitrogen availability and growing degree days
Abstract Cover crop mixtures can provide multiple ecosystem services but provisioning of these services is contingent upon the expression of component species in the mixture. From the same seed mixture,…
Adaptation and Mitigation amid the Consequences of Failure
Abstract Societies once could choose between changing direction or dealing with climatic disaster; now it is necessary to do both at once. The best-laid plans for mitigation would be hard…
Mating compatibility and fertility studies in an herbaceous perennial Aster undergoing de novo domestication to enhance agroecosystems
Abstract Under NT management, there are several pathogens that often increase, such as Rhizoctonia solani and Fusarium spp., or decrease, such as Gaeumannomyces graminis and Pratylenchus neglectus. While NT farming…
Abiotic and biotic context dependency of perennial crop yield
Perennial crops in agricultural systems can increase sustainability and the magnitude of ecosystem services, but yield may depend upon biotic context, including soil mutualists, pathogens and cropping diversity. These biotic…
New Food Crop Domestication in the Age of Gene Editing: Genetic, Agronomic and Cultural Change Remain Co-evolutionarily Entangled
The classic domestication scenario for grains and fruits has been portrayed as the lucky fixation of major-effect “domestication genes.” Characterization of these genes plus recent improvements in generating novel alleles…
Roadmap for Accelerated Domestication of an Emerging Perennial Grain Crop
Shifting the life cycle of grain crops from annual to perennial would usher in a new era of agriculture that is more environmentally friendly, resilient to climate change, and capable…
Carbon and water relations in perennial Kernza (Thinopyrum intermedium): An overview
Abstract Perennial crops have been proposed as a more sustainable alternative to annual crops, because they have extended growing seasons, continuous ground cover, reduced nutrient leakage, and sequester more carbon…
