A revision of Juncus subgenus genuini (Juncaceae) in the Pacific states

Creator:: Lint, Harold LeRoy
Abstract:: A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...

Characterization of a bacterial agglutinin from legumes

Creator:: Jasalavich, Claudia Ann
Abstract:: Leaves of Phaseolus vulgaris cv. 'Dark Red Kidney' and cv. 'Red Mexican U. I. 31', Phaseolus lunatus cv. 'Fordhook Bush 242', Phaseolus mungo cv. 'Berken', and Glycine max cv. 'Wilkin' have been shown to contain a factor which consistently agglutinated the saprophyte Pseudomonas putida; another saprophyte Pseudomonas fluorescens was agglutinated...

Morphology, ultrastructure and mating of sporidia of a wheat-bunt fungus, Tilletia caries (DC.) Tul.

Creator:: Kollmorgen, James Frederick
Abstract:: The teliospore of Tilletia caries germinates to produce a promycelium with a whorl of primary sporidia at its tip. The time between emergence of the promycelium and the development of primary sporidia averaged 2.3 h. Fusion between compatible sporidia occurred within an additional 3.8 h. Primary sporidia appeared to be...

The biology and pathogenicity of a sheath nematode Hemicycliophora similis Thorne, 1955

Creator:: McKewan, Jeanette Anne
Abstract:: A study, using greenhouse and laboratory experiments, was made of Hemicycliophora similis from Bandon, Oregon to determine: identity and morphometrics, time and development of a life cycle, host plant preferences and optimum environmental conditions for reproduction and pathogenicity. Morphometric investigations revealed discrepancies between the measurements of this nematode species and...

A chemosystematic study of the phylogenetic position of Arabidopsis thaliana (L.) heynh. (Brassicaceae) employing numerical methods

Creator:: Kaplan, Hesh J.
Abstract:: The Brassicaceae, Mustard Family, is a well marked natural family, whose tetramerous flowers, tetradynamous stamens, and distinctive bi- carpellary fruits, clearly distinguish it from related families. It is a large family of some 3, 000 recognized species and over 300 genera. Although numerous attempts have been made over the past...

Ethylene production from cultures of Cylindrocladium and from Cylindrocladium-infected azalea leaves

Creator:: Axelrood, Paige Ellen
Abstract:: Ethylene was produced by Cylindrocladium floridanum and C. scoparium in culture. Production was methionine dependent and maximal during the active growth phase of the fungus, beginning shortly after spore germination. More ethylene was produced sooner by C. floridanum than C. scoparium. Ethylene was produced by Cylindrocladium both from active mycelium...

Development and control of benomyl-tolerant Botrytis cinerea strains on snap beans (Phaseolus vulgaris)

Creator:: Johnson, Earl Ray
Abstract:: Benomyl-tolerant Botrytis cinerea was found in snap bean fields throughout the Willamette Valley while no tolerant isolates of Whetzelinia sclerotiorum were detected. Thirty-five benomyl-tolerant isolates of B. cinerea had slower radial growth rates than eighteen benomyl-sensitive isolates. Sporulation of an aggressive tolerant isolate was not stimulated when grown on benomyl-treated...

The glutamine synthetases in soybean root nodules and free-living Rhizobium japonicum

Creator:: Guevara, Juan Garcia
Abstract:: Glutamine synthetase activity is present in both the cytosol and bacteroid fractions of soybean root nodules. Total activity measurements indicate that at least 90% of the activity in nodules is located in the cytosol. Results reported by McParland, et al. (29), showed that many properties of glutamine synthetase from nodule...

Laboratory studies of bacteriophagous nematodes as potential vectors of insect pathogens

Creator:: Wright, Billie Dean
Abstract:: Three species of bacteriophagous nematodes, Pristionchus lheritieri (Maupas) Paramanov, Pelodera chitwoodi (Bassen) Dougherty and Rhabditis sp. were studied to determine their potential roles as vectors of selected insect pathogens, Bacillus thuringiensis Berliner, Beauveria bassiana (Balsamo) Vuillemin, Metarrhizium anisopliae (Metchnikoff) Sorokin and a nuclear polyhedrosis virus of Trichoplusia ni Hubner.
