Domesticated forms of wheat exhibit traits that have increased their adaptation
to cultivation by humans. Some of the most critical adaptive differences involve
changes to morphological features that make the crop easier to harvest like ear rachis
stiffness (brittle to non-brittle rachis) and the ease with which the seed is...
Celiac disease, an autoimmune response triggered by the consumption of seed storage proteins of cereals, affects an estimated 1% of the human population. In the case of wheat (Triticum aestivum L.), one of the world’s most consumed cereals, alcohol-soluble proteins, the gliadins, have been identified as the allergy-eliciting agents. Previous...
Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...
The fashion industry is becoming increasingly unsustainable. Overconsumption of clothing, exacerbated by fast fashion, is worsening the environmental impact of both the production and disposal of clothing. Clothing reuse, particularly thrifting, is gaining popularity, yet most donated clothes still never get sold. I have developed a plan for a small...
Between 1900 and 1920 women were responsible for much of the social and
political activity in the United States. Recent work by feminist historians has revealed
that women were interested in a broad range of issues at the turn of the twentieth
century. The American Left addressed such issues as...
The development of winter 6-row malting barley varieties is an objective of the OSU program. The program's winter germplasm is quite susceptible to Barley Yellow Dwarf Virus (BYDV). The program recently released the spring 2-row variety Orca, which carries the Yd2 gene for BYDV resistance. The objective of this project...
In Washington State, regional leaders have acknowledged the intrinsic value of nature and are striving to provide equal consideration to both human and nonhuman nature in the quest to restore the Puget Sound. But watershed-based committees supporting this work have faced challenges to effectively consider human wellbeing (HWB) in their...
Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...
Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...
Cephalosporium stripe, caused by the soil-borne ascomycete Cephalosporium gramineum, is becoming an increasingly important disease of winter wheat (Triticum aestivum) in several areas of the world, especially where stubble mulch is practiced to maintain soil moisture and prevent erosion. As cultural control of the disease is infeasible and no fungicides...
