Distinguishing Abiotic from Biotic Stressors in Perennial Grain Crops: Nutrient Deficiency Symptoms in Silphium integrifolium and Thinopyrum intermedium
Scientists in The Land Institute’s Crop Protection Genetics Program and research collaborators co-authored a paper documenting the impact of nutrient deficiencies on various aspects of plant growth and their implications…
Identification and Molecular Characterization of Dahlia common mosaic virus from Silphium spp, a new natural host of the virus
Abstract: Dahlia common mosaic virus (DCMV) was previously reported to infect only dahlias (Dahlia variabilis). However, DCMV was identified for the first time in association with Silphium spp. The complete…
Assessing effective mechanical and chemical strategies for managing Eucosma giganteana (Lepidoptera: Tortricidae) in the perennial oilseed crop, Silphium integrifolium (Asteraceae: Heliantheae)
The Land Institute’s Crop Protection Ecology and Perennial Oilseeds teams published a paper assessing the most functional methods for managing Eucosma moth (Eucosma giganteana), a pest that specializes in and commonly…
Adaptation of pathogens to their local plant host, Silphium integrifolium, along a precipitation gradient
Featuring five researchers from The Land Institute, this manuscript documents the prevalence of plant pathogens associated with human-induced changes to the planet’s climate and ecosystems, with the perennial prairie plant…
Evaluation of the Intra- and Interspecific Development of Different Accessions of Silphium perfoliatum L. and Silphium integrifolium Michx.
Research from The Land Institute’s collaborators in Germany details the use of perennial species for biomass production, with the goal of analyzing the value of Silphium for the energy production…
Sensing Scale in Experimental Gardens: Un-Lawning With Silphium Civic Science
By designing transdisciplinary and participatory methods of engagement, The Land Institute’s Civic Science Program harnessed public participation to visualize cross-scalar relationships in gardening projects through the medium of Silphium integrifolium,…
Domestication effects on nitrogen allocation, internal recycling, and nitrogen use efficiency in the new perennial crop Silphium integrifolium (Asteraceae)
Abstract Improvements in seed yield during domestication and breeding are frequently achieved moving plants from the conservative syndrome of the plant economic spectrum towards the more acquisitive side, changing how…
Changes to architecture of Silphium integrifolium Michx. during domestication reveal new trade-offs for yield
Ongoing domestication of whole leaf rosinweed, Silphium integrifolium Michx., as a perennial oilseed and forage crop aims to increase yields while limiting decreases in other desirable traits (i.e., trade-offs). Two…
Seeding date affects seed and biomass yield of Silphium integrifolium Michx. (silflower)
Abstract Silphium integrifolium Michx. (silflower [Asteraceae]) is an emerging perennial oilseed and biomass crop with potential to supply ecosystem services, but optimum seeding dates for establishment are unknown. Our objective…
Development of First Linkage Map for Silphium integrifolium (Asteraceae) Enables Identification of Sporophytic Self-Incompatibility Locus
SUMMARY Silphium integrifolium (Asteraceae) has been identified as a candidate for domestication as a perennial oilseed crop and has a sporophytic self-incompatibility system—the genetic basis of which is not well understood…
Silflower Seed and Biomass Responses to Plant Density and Nitrogen Fertilization
Silflower (Silphium integrifolium Michx.) is a potential perennial oilseed crop that can provide ecosystem services; however, its seed, oil, and biomass yield potential are unknown. Our objectives were to determine the…
Patterns of genetic variation in a prairie wildflower, Silphium integrifolium, suggest a non-prairie origin and locally adaptive variation
PREMISE: Understanding the relationship between genetic structure and geography provides information about a species’ history and can be used for breeding and conservation goals. The North American prairie is interesting…
