A biochemical analysis of the interaction of victorin and oats

Creator:: Navarre, Duroy A.
Abstract:: Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as the P protein of the glycine decarboxylase complex (GDC)....

Pyrenophora tritici-repentis : investigation of factors that contribute to pathogenicity

Creator:: Holman, Thomas W.
Abstract:: Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...

Sensitivity of wheat genotypes to a toxic fraction produced by Cephalosporium gramineum and correlation with disease susceptibility

Creator:: Rahman, Mahfuzur
Abstract:: 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...

Phylogeography and Evolution of Effector Genes in Phytophthora Species

Creator:: Shakya, Shankar K.
Abstract:: Plant pathogens in the genus Phytophthora are known to cause disease on field crops, nursery plants, and forest trees. The best known example probably is Phytophthora infestans, which triggered the infamous Irish potato famine. Other important Phytophthora species include: P. ramorum (sudden oak death pathogen), P. sojae (soybean root rot...

Studies on the centromere-specific histone, CenH3, of Neurospora crassa and related ascomycetes

Creator:: Phatale, Pallavi A.
Abstract:: In eukaryotes, the defined loci on each chromosome, the centromeres, accomplish the critical task of correct cell division. In some organisms, centromeres are composed of a euchromatic central core region embedded in a stretch of heterochromatin and the inheritance and maintenance of centromeres are controlled by dynamic epigenetic phenomena. Although...

Nature of resistance to Verticillium dahliae Kleb. in strains of peppermint (Mentha piperita L.) developed by irradiation

Creator:: Sherrod, Leslie Lynn, 1940-
Abstract:: Verticillium dahliae Kleb. causes a wilt disease of peppermint. Attempts to control the disease by soil fumigation, crop rotation, flaming of stubble, and deep plowing have met with only limited success. Development of resistant varieties through conventional breeding procedures is difficult because commercial peppermint is male-sterile. Several strains of commercial...

Foliar respiration in an old-growth coniferous forest

Creator:: Cooper, Clifton E.
Abstract:: Foliar respiration forms a large component of the carbon balance of any coniferous forest. We examine seasonal, interannual, spatial and interspecific variation of foliar maintenance respiration in a forest in Washington, USA, with measurements made quarterly for >4 years on 400-year old trees of Pseudotsuga menziesii, Tsuga heterophylla and Thuja...

Investigations of Black Leg and Light Leaf Spot on Brassicaceae Hosts in Oregon

Creator:: Claassen, Briana J.
Abstract:: The Pacific Northwest is an internationally important region for the production of Brassica seed and other seed crops including grass seed. Oregon lawmakers mandated research into the co-existence of canola (Brassica napus) with other Brassica production in the Willamette Valley and House Bill 2427 was signed into law in 2013,...
