A phenotypic integration approach to breeding seedlings for early vigor and drought resistant traits
Research partners in Argentina working with Siplhium integrifolium (silflower) for its potential as a perennial oilseed crop looked at the potential to analyze physical traits such as leaf traits in the…
Disease resistance gene count increases with rainfall in Silphium integrifolium
Researchers at the University of Minnesota, including The Land Institute’s Kelsey Peterson (Whiting), sequenced R genes (a category of plant disease resistance genes) in several wild populations of silphium integrifolium,…
A Perennial Green Revolution to address 21st-century food insecurity and malnutrition
Researchers at Colorado State University published a paper discussing the benefits of pursuing a “Perennial Green Revolution” where the further development of perennial grains like Kernza®, silflower (a perennial oilseed…
Perennial Grains and Oilseeds: Current Status and Future Prospects
Doug Cattani, perennial grain research partner of The Land Institute from the University of Manitoba in Canada, provided an overview on the role of perennial grains in the future direction…
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…
