Perennial Flax: Developing a New Crop Via Adaptive Management

peer-reviewed journal publication, Perennial Flax /

Authors: Zachary A. Pull, Burton L. Johnson, Brent S. Hulke, Greta G. Gramig Publication Date: November 7, 2022 Abstract: Perennial Lewis flax (Linum lewisii Pursh) is a potential new crop that could provide both high quality oil seed and enhance agroecosystem sustainability by provisioning multiple ecosystem services. As a novel crop, determining agronomic best practices and […]

Double-cropping oilseed sunflower after winter camelina

peer-reviewed journal publication, Sunflower /

Authors: R.W. Gesch, Y.A. Mohammed, M.K. Walia, B.S. Hulke, J.V. Anderson Publication Date: March 12, 2022 Abstract: Double-cropping as a means of sustainably intensifying oilseed production could promote farmer adoption of new and alternative use oil crops like camelina [Camelina sativa (L.) Crantz]. Previous research indicated that double-cropping sunflower (Helianthus annuus L.) after winter camelina in the upper Midwest USA tended to reduce sunflower seed yield and

Assessment of biogeographic variation in traits of Lewis flax (Linum lewisii) for use in restoration and agriculture

peer-reviewed journal publication, Perennial Flax /

Authors: Peter Innes, André Gossweiler, Scott Jensen, Derek Tilley, Loren St. John, Thomas Jones, Stanley Kitchen, Brent S. Hulke Publication Date: February 4, 2022 Abstract: Lewis flax (Linum lewisii) is widely distributed across western North America and is currently used in native ecosystem restoration. There is also growing interest in de novo domestication of Lewis flax as

Aberrant RNA splicing due to genetic incompatibilities in sunflower hybrids

peer-reviewed journal publication, Sunflower /

Authors: Chris C. R. Smith, Loren H. Rieseberg, Brent S. Hulke, Nolan C. Kane Publication Date: November 1, 2021 Abstract: Genome-scale studies have revealed divergent mRNA splicing patterns between closely related species or populations. However, it is unclear whether splicing differentiation is a simple byproduct of population divergence, or whether it also acts as a

Breeding crops for climate resilience

Climate, peer-reviewed journal publication /

Authors: Peter Lagridge, Hans Braun, Brent Hulke, Eric Ober, and B. M. Prasanna Publication Date: May 27, 2021 Abstract: In enhancing the resilience of our crops to the impacts of climate change, selection objectives need to address increased variability in the production environment. This encompasses the effects of more variable rainfall and temperatures than currently

Breeding for sustainable oilseed crop yield and quality in a changing climate

Climate, peer-reviewed journal publication /

Authors: Ziv Attia, Cloe S. Pogoda, Stephan Reinert, Nolan C. Kane, and Brent S. Hulke Publication Date: January 26, 2021 Abstract: As the effects of climate change continue to alter crop-growing conditions year-to-year on both prime and marginal agricultural landscapes, we must consider the effects not only on yield but also on quality. This is

A Greenhouse Method to Evaluate Sunflower Quantitative Resistance to Basal Stalk Rot Caused by Sclerotinia sclerotiorum

peer-reviewed journal publication, Sunflower /

Authors: William Underwood, Christopher G. Misar, Charles Block, Thomas J. Gulya, Zahirul Talukder, Brent S. Hulke, and Samuel G. Markell Publication Date: December 2, 2020 Abstract: Resistance of sunflower to basal stalk rot (BSR) caused by the fungus Sclerotinia sclerotiorum is quantitative, controlled by multiple genes contributing small effects. Consequently, artificial inoculation procedures allowing sufficient throughput and

Genetic loci underlying quantitative resistance to necrotrophic pathogens Sclerotinia and Diaporthe (Phomopsis), and correlated resistance to both pathogens

peer-reviewed journal publication, Sunflower /

Authors: Cloe S. Pogoda, Stephan Reinert, Zahirul I. Talukder, Ziv Attia, Erin C. E. Collier-zans, Thomas J. Gulya, Nolan C. Kane, and Brent S. Hulke Publication Date: October 27, 2020 Abstract: Necrotrophic pathogens can avoid or even benefit from plant defenses used against biotrophic pathogens, and thus represent a distinct challenge to plant populations in

Determination of Virulence Phenotypes of Plasmopara halstedii in the United States

peer-reviewed journal publication, Sunflower /

Authors: Michelle A. Gilley, Thomas J. Gulya, Gerald J. Seiler, William Underwood, Brent S. Hulke, Christopher G. Misar, and Samuel G. Markell Publication Date: September 21, 2020 Abstract: Downy mildew, caused by Plasmopara halstedii (Farl.) Berl. and de Toni, is an economically important disease in cultivated sunflowers, Helianthus annuus L. Resistance genes incorporated into commercial hybrids are used as

Aberrant regulation of RNA splicing in sunflower hybrids may underlie intrinsic incompatibilities

peer-reviewed journal publication, Sunflower /

Authors: Chris C R Smith, Loren H Rieseberg, Brent S Hulke, Nolan C Kane Publication Date: September 8, 2020 Abstract: Alternative spicing is an integral part of gene expression in multicellular organisms that allows for diverse mRNA transcripts and proteins to be produced from a single gene. However, most existing analyses have focused on macro-evolution,
