Identification and characterization of seven ROP GTPases in Zea mays

Creator:: Christensen, Todd M.
Abstract:: Regulation of cell division and expansion are critical for plant development. The mechanisms that control these processes are not clearly understood in higher plants. In other eukaryotic models it has been shown that the highly conserved Rho family GTPases play a crucial role in these mechanisms. One distinct subset of...

Role of inoculum sources of Botrytis cinerea in the epidemiology of gray mold of snap beans

Creator:: Johnson, Kenneth Bjorn
Abstract:: Spore dispersal gradients and pod disease gradients from point inoculum sources of Botrytis cinerea were measured over time in two snap bean field experiments. Laboratory grown inoculum was placed at ground level in a 30 x 30 cm square at bloom initiation and removed at full bloom. Dispersal of inoculum,...

Factors affecting germination of endomycorrhizal spores

Creator:: Daniels, Barbara Ann
Abstract:: Four isolates of Glomus mosseae, collected from diverse geographic locations, were pot cultured on varied host plants or stored in the same soil as collected. Spores of three isolates failed to germinate on any of five agar media while the fourth germinated well on all media. Lack of germination on...

The effects of abscisic acid on gene expression during wheat germination

Creator:: Ballo, Barbara
Abstract:: Germination of immature (Stage III) and mature (Stage V) wheat (Triticum aestivum L. var. Chinese Spring and Yamhill) embryos is prevented by the inclusion of 10⁻⁴ M abscisic acid (ABA) in culture medium. In addition, Stage III embryos develop into mature embryos in culture medium containing ABA. In the absence...

Fescue taxonomy in the Pacific coast states

Creator:: Wilson, Barbara L.
Abstract:: Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...

Relationship of extra-matrical hyphae of vesicular-arbuscular mycorrhizal fungi to plant growth response

Creator:: Kough, John Lawrence
Abstract:: The colonization of several species of plants by vesicularar-buscular mycorrhizae (VAM) was studied to determine how host, soil, or symbiont factors interacted to enhance growth of the host plant. Seedlings of two species of the Cuppressaceae and two of the Taxodiaceae formed VAM; colonization significantly improved growth. This response to...
