Identifying genes that influence the ability of Rhodococcus to benefit plants

Creator:: Lederhos, Heidi
Abstract:: 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...

Characterizing novel bacterial isolates that inhibit the growth of gall-forming phytopathogenic bacteria

Creator:: Belcher, Michael S.
Abstract:: Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...

Freeze tolerance: comparing two geographically isolated populations of the cinnabar moth

Creator:: Lieberenz, Tim, Mattsson, Monte, Bürgi, Linda, and McEvoy, Peter
Abstract:: 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...

Soil solarization at an organic farm: effects on weed emergence, soil nutrients and soil microbial communities

Creator:: Trammell, Caleb, Eberhart, Joyce, and Parke, Jennifer L.
Abstract:: 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.

Host plant dependent disease progression of the microsporidian parasite Nosema tyriae on Cinnabar moth larvae

Creator:: Berns, Kathryn, Buergi, Linda, and McEvoy, Peter
Abstract:: 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...

Small secreted proteins of pyrenophora tritici-repentis and their role in wheat Infection

Creator:: Hernandez, Jason, Manning, Viola, Pandelova, Iovanna, and Ciuffetti, Lynda M.
Abstract:: Host-selective toxins (HSTs) secreted by the pathogenic isolate of Pyrenophora tritici-repentis, BFP, are major pathogenicity factors in tan spot disease of wheat. Along with characterized HSTs such as Ptr ToxA (ToxA), BFP secretes at least two more uncharacterized toxic components. In an attempt to identify these additional components, 12 candidate...

Development of a new molecular diagnostics tool for Agrobacterium tumefaciens

Creator:: Fuller, Skylar, Savory, Elizabeth, Weisberg, Alex, and Chang, Jeff
Abstract:: 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...

Male gametophyte specific expression helps identify a conserved gene associated with increased pollen fitness

Creator:: Colebrook, Sean Jr., Unger-Wallace, Erica, and Vollbrecht, Erik
Abstract:: 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...

Constructing a gene expression atlas of Chia (Salvia hispanica)

Creator:: Phillips, Jeremy Levi, Geniza, Matthew, Haq, Ebaad, and Jaiswal, Pankaj
Abstract:: • 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,...

Resource Type:: Presentation

Discovering the roles of myosin and exocyst proteins in cell expansion of Arabidopsis thaliana

Creator:: Goodrich, Danielle
Abstract:: The overall objective of this research was to determine which, if any, myosin XI proteins and exocyst proteins play a role in growth of Arabidopsis thaliana hypocotyls and root hairs. This involved the study of whether exocyst and myosin proteins work together during cell expansion within these two plant parts....
