In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...
Root rot of sweet corn in western Oregon and Washington is a significant disease that
can reduce yield of intolerant cultivars of processed sweet corn by fifty percent. Root rot
is caused by a complex of soilborne organisms, including Drechslera sp., Phoma
terrestris, and Pythium arrhenomanes. Processors have adopted tolerant...

Mycotoxins are food-borne toxins produced by molds which are commonly found on animal feeds of economic significance. Toxic doses of these compounds vary widely across livestock species, and even within a species when considered across all stages of development and production. This variation is due to the wide range of...
Seed dormancy is defined as the inability of viable seeds to germinate under conditionsotherwise favorable for germination. Dormancy provides a strategy for seeds to germinateat an appropriate time. Abscisic acid (ABA) is a major hormone involved in the regulationof seed dormancy. To elucidate the molecular mechanisms of dormancy, the twoexperimental...
Wheat is a globally traded staple crop. Wheat is important in human diets because of its agronomic adaptability, physical characteristics, functionality for the production of leavened products and nutritional value. Two significant characteristics make wheat an important staple food-crop. First, the proteins present in wheat endosperm have attributes that enable...
High protein wheat seeds frequently perform better than low
protein seeds of the same variety. Protein content of seeds can be
increased by management practices, the most important of which is
rate and timing of N applications. The purpose of this study was to
determine the chemical, biochemical and physiological...
Studies on net carbon exchange, ¹⁴
C assimilation, and growth
analysis were done on four cultivars of high yielding soft white
winter wheat (Triticum aestivum L. em Thell), Anza/Sturdy, Hill-
81, Stephens, and Yamhill, which differ in morphology, maturity,
and yield, to see if differences in production and distribution
of...
Hard red winter wheat has the potential to be an alternative crop
in the Pacific Northwest, however percent grain nitrogen has been
unacceptably low and grain yields have been about only 80% of soft white
winter wheat. During the late spring and the summer months there is
usually little rainfall,...
Oomycetes are some of the most devastating pathogens, causing upwards of billions of dollars of damage each year to plants. They also diminish ecological diversity and health through the destruction of trees and shrubs. The genome sequence of Pseudoperonospora cubensis, an obligate plant pathogen and causative agent of downy mildew...
