Distribution of Acremonium coenophialum in developing seedlings and inflorescences of Festuca arundinacea

Creator:: Cook, Kathy L.
Abstract:: Acremonium coenophialum is an endophytic fungus which infects the reproductive and vegetative tissue of tall fescue. Interest in this fungus was sparked by research which linked its presence in tall fescue with reduced weight gains and alkaloid-like poisoning in cattle. Incomplete information was available on the endophyte's life or disease...

Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

Creator:: Marsden, Katherine E.
Abstract:: The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

Distribution and characterization of ice nucleation active strains of Pseudomonas syringae from diseased woody plants and grasses

Creator:: Baca, Steve
Abstract:: In a recent survey, it was observed that many woody plant species grown in Pacific Northwest nurseries exhibited disease symptoms typical of a bacterial infection and Pseudomonas syringae was commonly isolated from these tissues. The distribution of the ice nucleation phenotype among P. syringae strains recovered from these infected woody...

Trichoderma spp. : distribution in stumps infested with Phellinus weirii and growth and antagonism in vitro

Creator:: Goldfarb, Barry
Abstract:: To determine which isolates will most rapidly replace Phellinus weirii in stumps and roots, Trichoderma spp. were isolated from P. weirii-infested stumps and roots, identified, and examined for growth rates and lethal effects on P. weirii in vitro. Phellinus weirii-infested Douglas-fir stumps and stump roots were sampled for microorganisms by...

Studies on inhibitory compounds produced by Agrobacterium radiobacter strain 84

Creator:: Staver, Michael J.
Abstract:: A study was made of compounds produced by Agrobacterium radiobacter strain 84 that are inhibitory to some pathogenic strains of A. tumefaciens. Agrocins (inhibitory compounds) were partially purified from large volumes of A. radiobacter strain 84 culture supernatants to determine (i) if more than one agrocin is produced, (ii) if...
