Thauera butanivorans sp. nov., a C₂–C₉ alkane-oxidizing bacterium previously referred to as ‘Pseudomonas butanovora’

Creator:: Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...

Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:: Garrett, Karen A.
Abstract:: Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

Effect of wheat cultivar mixtures on populations of Puccinia striiformis races

Creator:: DiLeone, Julie A.
Abstract:: This study quantified the frequency of simple versus complex races of Puccinia striiformis Westend. in mixtures of wheat cultivars possessing different race-specific resistance genes. A simple race of a pathogen can infect only one component, and a complex race of the pathogen can infect two or more components of an...

Genetic diversity and interactions in populations of plants and pathogens

Creator:: Knott, Elizabeth A.
Abstract:: Two experiments involving interactions between wheat (Triticum aesitivium L.) cultivars and rust pathogens were investigated. One experiment evaluated the aggressiveness (measured by infection efficiency and latent period) of populations of Puccinia recondita Rob. when inoculated on the cultivar they were isolated from, their "own" cultivar, and when inoculated onto other...

Comparative gibberellin relationships in tall and dwarf peas (Pisum sativum L.)

Creator:: Anderson, James David
Abstract:: Experiments were performed to determine whether a direct correlation exists between the growth rates of tall and dwarf peas grown either in the light or in the dark and endogenous gibberellin (GA) content. Three separate but related experimental approaches were utilized: (1) the determination of possible qualitative and /or quantitative...

Purification and partial characterization of a virus associated with korogwe leaf spot disease of sisal

Creator:: Mpunami, Anatolia
Abstract:: Sisal Wave sisalana Perrine), one of Tanzania's main cashcrops, is severely affected by korogwe leaf spot disease (KLS).Infected plants show chocolate brown, concentric, scablike eruptions on both surfaces of mature leaves, and produce stained, low-quality fiber. A flexuous, rod-shaped virus was isolated from KLS-infected sisal leaves and studied at Oregon...
