Summary of experimental results, 1981. Geraldton: Brown spot (Pleiochaeta setosa) was widespread. Root rots were not considered generally to be a problem in 1981.Three Springs: Fungal root rots were commonly observed. Brown spot leaf and stem infection was also prevalent. Moora: Brown spot was the most prevalent. Northam: Crops were generally healthy. Albany: Crops were generally healthy Sclerotinia being present. Bridgetown: Brown spot was the main disease present. Root rots were also present. In December, a widespread disorder occurred, Late brown spot infection is suspected. An important point emerging from the programme is that often the lines showing Phomopsis resistance …

Screening Of Clovers For Resistance To Clover Scorch, D. L. Chatel

Experimental Summaries - Plant Research

Clover Scorch (Jointly with Dr C.M. Francis). One thousand four hundred and seventy six legumes were screened in the field at the Denmark Research Station for susceptibility to clover scorch. They comprised 1440 subterranean clovers, eight other Trifoliums, two medics and 26 serradellas. The clovers from Australia gave interesting results. Thirty four of them were selections of Seaton Park, chosen by R.C. Rossiter and W. J. Collins on the basis of their variation. They did not differ in their reaction to clover scorch; all gave rating of 9. Twenty-six lines of Woogenellup from W.A. and 12 of Woogenellup and Morrar …

Lupin root disorder. Resistance to lupins to Phomopsis leptostromiformis (Fungal ratings by P. McR. Wood and F.M. O'Donnell, data compiled by J. Hamblin, Plant Production Division) Phomopsis levels on any particular genotype are influenced by environment. Therefore material selected for Phomopsis resistance is done so on its being better than average over all sites. Data for the Plant Breeders' S2-l trial at Avondale (ARS), Badgingarra (BRS), Chapman (CRS), Esperance (ERS) and Mt. Barker (MTRS) are shown in Table 3.

A Potential Macroregulatory Mechanism For Growth Regulation In Neurospora Crassa, Martha Mooney

Biological Sciences Theses & Dissertations

Neurospora produces a phase specific, cationic mucopolysaccharide composed primarily of galactosamine (GAG-MP) which becomes part of the cell wall and is later secreted into the media. Its appearance coincides with the onset of the restricted phase of growth and causes efflux of small molecular weight metabolites when incubated with conidial cells. This activity may be a product of electrostatic interactions of the GAG-MP with the conidial plasma membrane. The activity is blocked by acetylation of the primary amines on the molecule, digestion by enzymes that hydrolyze carbohydrate linkages and the inclusion of NaCl (lM) in the GAG-MP/conidia reaction mixture. The …

Demonstration Of Unique Mycelial Components In Candida Albicans, David Jon Mancuso

Biological Sciences Theses & Dissertations

Mycelial (M) and blastopore (B) cell homogenates of Candida albicans strain BJ85 were compared to detect and recover unique M components. Qualitative differences in the protein and lipid content of Mand B homogenates were suggested by discontinuous polyacrylamide gel electrophoresis (DPAGE). In addition, a quantitative and possibly qualitative shift in the protein content during germ tube formation was implied by DPAGE. Unique M components were detected using both DPAGE and immunoelectrophoretic (IE) techniques. One unique M component by DPAGE, four by IE, and two by combined DPAGE and IE techniques were suggested. Of these three methods, only DPAGE and the …

Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoretic Studies Demonstrating Cytoplasmic Protein Components Unique To The Mycelial Phase And To The Yeast Phase Of Candida Albicans, Theresa Catherine Burgess

Biological Sciences Theses & Dissertations

Blastospore and mycelial cytoplasmic extracts from four strains of Candida albicans, varying in virulence, were compared by sodium dodecyl sulfate (SDS) polyacrylamide disc gel electrophoresis Cytoplasmic extracts were made by disrupting the cultures in a Braun homogenizer followed by ultracentrifugation. The supernatant fractions were then resolved on polyacrylamide gels containing SDS. Each of the preparations yielded a distinct pattern. There were mycelial specific and blastospore specific protein bands. There were more components resolved from the blastospore phase cytoplasmic extracts than from the mycelial phase cytoplasmic extracts. There were bands common to both phases. These results demonstrate protein components unique …

Summary Of 1975 Field Experiments With Advisers: "Rape Blackleg Disease Fungicide Trials", M J. Barbetti

Experimental Summaries - Plant Research

During 1973 and 1974 a large range of fungicide spray and seed treatment schedules were tested. The 1973 results were, on the whole, not very encouraging, but the very early post-germination spray, two weeks after germination, did indicate a possible means of control. In view of the 1973 results, in the 1974 trials fungicidal sprays were applied early, and a new method of application of fungicide to the seed, known as "prilling" was used. Using fungicide seed prills and seedless fungicide prills the idea was to have the fungicide mixed with materials which dispersed upon wetting, so releasing and making …

A Photomicrographic Guide To The Saprolegniaceae Of Illinois, Ronald L. Butler

Masters Theses

There is a paucity of information concerning the occurrence and distribution of the Saprolegniaceae of Illinois. These fungi, commonly called "water molds", are of particular interest as many are potential parasites of fish, crustaceans, and other aquatic plant and animal life. It is of considerable interest to students of the fungi and of practical value to the fisheries biologists and environmentalists to have available a means of identification for these organisms.

This paper provides a descriptive and photomicrographic account of the Saprolegniaceae of Illinois. Included herein are dichotomous keys to the genera of this family as well as generic descriptions …

A Study Of Puccinia Graminis And Cronartium Ribicola, Duane W. Hughes

Graduate Student Research Papers

It was the purpose of this study (1) to review the literary history of rusts in the United States and in the Northwest in particular, ( 2) to learn where rusts generally are found geographically, (3) to gain further information regarding the etiology of wheat rust (Puccinia graminis tritici), of white pine blister rust (Cronartium ribicola) and to become enlightened on other rusts, (4) to learn ways of controlling the two rusts, black stem rust of wheat and white pine blister rust, and to gain an appreciation of the economic importance of rust prevention.
