Chromosome-scale Genome Assembly of Lewis Flax (Linum lewisii Pursh.)

Authors: Peter A. Innes, Brian C. Smart, Joseph A.M. Barham, Brent S. Hulke, Nolan C. Kane Publication Date: October 10, 2023 Abstract: Linum lewisii, a perennial blue flax native to North America, holds potential as a sustainable perennial crop for oilseed production due to its ecological adaptability, upright harvestable structure, nutritious seeds, and low insect

Pollen quantity, but not grain size, is correlated with floret size in cultivated sunflower, Helianthus annuus L.

Authors: Jarrad R. Prasifka, Zoe M. Portlas, and Brent S. Hulke Publication Date: September 25, 2023 Abstract: Cultivated sunflower (Helianthus annuus L.) pollen helps attract wild and managed bees needed to produce hybrid seed. Pollen quantity and grain size (≈quality) are affected by the environment, but are also heritable traits of interest for breeding. Florets from

Field Trip

On Tuesday, August 15 the Hulke Lab took a visit to the CHS sunflower nursery near Grandin, North Dakota. They gave us a tour around the field, showing us a few projects that have been in the works and a few different breeds of sunflowers. We then visited their sunflower processing facility. We got to

First steps toward developing Lewis flax (Linum lewisii Pursh) as an agronomic crop

Authors: Zachary A. Pull, Greta Gramig, Brent S. Hulke, Andre Gossweiler, and Burton Johnson Publication Date: August 14, 2023 Abstract: Perennial Lewis flax (Linum lewisii Pursh) has the potential to be grown as a new oilseed crop that could simultaneously meet commodity production, ecosystem service provisioning, and farm resiliency goals. Despite many potential benefits, Lewis flax

Gibberellic Acid

  Gibberellic Acid, GA3, is a plant growth hormone. It is added to select sunflower heads and sterilizes those specific plants, making them female. The Hulke Lab has been working on GA over the past 2 weeks. As seen in the photos above, the GA3 is placed in the center of the sunflower head very

Genetic mapping of a pollinator preference trait: Nectar volume in sunflower (Helianthus annuus L.)

Authors: Ashley C. Barstow, Jarrad R. Prasifka, Ziv Attia, Nolan C. Kane, Brent S. Hulke Publication Date: December 19, 2022 Abstract: Although high pollinator visitation is crucial to ensure the yields of pollinator-dependent crops, the quantitative trait loci (QTL) controlling nectar volume in sunflower (Helianthus annuus L.), a pollinator preference trait, have yet to be identified.
