Isolation and identification of dahlia viruses

Creator:: Lawson, Roger Harold
Abstract:: Three viruses were isolated from dahlias using a modification of Yarwood's leaf-disc method of inoculation. Two of these isolates have been reported previously in dahlias. In addition, a fourth virus was isolated using a liquid-nitrogen transmission technique. Dahlia virus isolate 1 possessed host range and thermal inactivation properties similar to...

Transmission of plant pathogenic bacteria and a bacteriophage of Agrobacterium tumefaciens (Smith and Townsend) Conn by a saprozoic nematode, Diplogaster lheriteiri Maupas

Creator:: Chantanao, Aroon
Abstract:: A saprozoic nematode, Diplogaster lheriteiri Maupas 1919, was studied to determine its relationship to the plant pathogenic bacteria, Agrobacterium tumefaciens (Smith and Townsend) Conn., Erwinia amylovora (Burrill) Winslow et al., Erwinia carotovora (Jones) Holland, Pseudomonas phaseolicola (Burk. ) Dows., Xanthomonas campestris (Pam. ) Dows. and to a phage of A....

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...

Some properties of ribonucleotide reductase in Rhizobium species

Creator:: Cowles, Joe Richard, 1941-
Abstract:: Ribonucleotide reductase from Rhizobium meliloti has been partially purified and characterized. The enzymatic reduction of ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme and dihydrolipoate. B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues in the reductase reaction. The affinity of the R. meliloti reductase system for B₁₂ coenzyme was...

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. Chlorine...

The interactions of Pratylenchus penetrans with host plants, Longidorus elongatus and Verticillium dahliae

Creator:: Yorston, John McKay
Abstract:: The root-lesion nematode, Pratylenchus penetrans (Cobb 1917). Filipjev and Shuurmans Stekhoven, 1941, is widely distributed throughout Oregon and other temperate zones of the world. Economically it is probably the most important plant parasitic nematode in Oregon because of its abundance, wide host range of economic plants and interactions with other...

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...
