Cytokinin oxidase activity from Phaseolus vulgaris L. cv. Great Northern callus tissues

Creator:: Chatfield, J. Mark
Abstract:: Cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv. Great Northern has been examined using an assay based on the oxidation of radioactively labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine (Ade). Conditions for the quantitative extraction and assay of the enzyme have been established. The substrate specificity...

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),...

Control of cytokinin autonomy in Phaseolus lunatus callus cultures

Creator:: Kim, Sang-Gu
Abstract:: The ability of N,N'-diphenylurea (DPU) to substitute for cytokininactive adenine derivatives in promoting callus growth of Phaseolus lunatus and Nicotiana tabacum has been examined. In general, DPU stimulated callus growth of P. lunatus at high concentrations and the growth of most callus tissues was irregular, while the response of tobacco...

Genetic recombination of the integrative plasmid pMC7105 of Pseudomonas syringae pv. phaseolicola involves repetitive sequences

Creator:: Szabo, Leslie J.
Abstract:: A strain of the phytopathogenic bacterium Pseudomonas syringae pv. phaseolicola, a pathogen of common bean Phaseolus vulgaris, harbors a 150 kilobase pair (kb) plasmid pMC7105. In one strain, LR719, pMC7105 is stably integrated in the bacterial chromosome. Imprecise excision of the pMC7105 replicon has been shown to result in the...

Biosystematic studies of Phacelia capitata (Hydrophyllaceae), a species endemic to serpentine soils in southwestern Oregon

Creator:: Shelly, J. Stephen
Abstract:: Phacelia capitata Rruckeberg is a member of the Phacelia magellanica polyploid complex (species group Magellanicae), a group of wide-ranging, polymorphic perennials in western North America related to the South American P. secunda (= P. magellanica). The purpose of this project was to determine, to the extent possible, the interrelationships of...

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...

Potential of Trichoderma sp. for inhibition of Botrytis cinerea and Sclerotinia sclerotiorum on snap beans

Creator:: Nelson, Mark E.
Abstract:: Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...
