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...

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.

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...

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...

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...

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 effects of cadmium on the nitrogen fixation system in Alnus rubra

Creator:: Wickliff, Carlos
Abstract:: Alnus rubra (Bong. ) seedlings were grown in sand culture and irrigated with nutrient solution containing CdCl₂ ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks with 50 and 100 mg CdCl₂ per liter of nitrogen-free nutrient solution decreased in situ nitrogenase...
