The Great Tohoku Earthquake and Tsunami of March 2011 generated nearly 1.5 million tons of floating debris. After 1-5 years of drifting with the currents across the Pacific, many debris items reached the NE Pacific coast carrying Japanese marine species that could colonize our shores. More than 84 marine algal...
Weed management is one of the main challenges for organic agriculture. Soil solarization has been shown to be an effective mitigation strategy for weeds and soil borne plant pathogens but few studies have been conducted in cooler climates such as the Pacific Northwest.
The purpose of this presentation is to show the source, methods, and results of creating a computerized display of the metabolic pathways of model plants Oryza sativa (rice) and Arabidopsis thaliana (thale cress) using the computer program PathVisio2. The finished products may be viewed and modified for free on www.wikipathways.org...
GRMZM2G372877 was identified as a gene with potential function in the male gametophyte based on its strong expression in mature pollen relative to other maize tissues (Chettoor et al. 2014). Identification of a Ds insertion mutation in this gene from the Brutnell/Vollbrecht collection provided further support for this hypothesis, as...
Symbioses are intimate interactions between two different organisms. In a pathogenic interaction, one organism benefits and the other is generally harmed; whereas in a mutualistic interaction, the members reciprocally benefit. Rhodococcus is a genus of Gram-positive bacteria that persist in a variety of terrestrial and aquatic ecosystems. Although better known...
Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...
Freezing to death in winter is a danger faced by ectothermic organisms throughout temperate climates. One adaptation of lepidopteran insects for overwinter survival is the sequestration of antifreeze solutes in the hemolymph prior to pupal diapause. This acts to depress freezing points during the long and immobile pupal stage during...
We sought to determine 1) the relationship between seedling
establishment rates of target native prairie species and field
levels of three soil nutrients (phosphate, nitrate, and ammonium)
recorded in fall, winter, and summer, 2) the effect of fire on
these three nutrients, and 3) the overall effect of fire on...
Agrobacterium tumefaciens causes the economically important plant disease, crown gall. These galls are the result of abnormal growth that manifests itself on either the root or the stem and can be devastating for the ornamental plant industry. Introduction of A. tumefaciens to a nursery can be highly detrimental and thus...

Salvia hispanica, also known as Chia, is an annual plant of the mint family, Lamiaceae. Chia is a vascular plant with perennating buds initially formed at or within the soil surface. Chia grows to roughly one meter tall at maturity, with leaves growing in opposite arrangement, small purple flowers,...
