Effect of Chitosan on Membrane Permeability of Suspension-Cultured Glycine max and Phaseolus vulgaris Cells.
Treatment of suspension-cultured Glycine max cv Harosoy 63 cells with soluble chitosan increased membrane permeability as shown by leakage of electrolytes, protein, and UV absorbing material, and polycation-induced leakage was inhibited by divalent cations. Expand
Laboratory studies to assess the risk of development of resistance to zoxamide.
The studies suggest that the risk of a highly resistant pathogen population developing rapidly in the field is much lower for zoxamide than for metalaxyl, but as with any site-specific fungicide, appropriate precautions against resistance development should be taken. Expand
Release of Calcium from Suspension-Cultured Glycine max Cells by Chitosan, Other Polycations, and Polyamines in Relation to Effects on Membrane Permeability.
The results suggest that the effect of polycations on permeability is not the direct result of calcium displacement from the cell surface but is probably due to cross-linking of surface components. Expand
Covalent binding of the benzamide RH-4032 to tubulin in suspension-cultured tobacco cells and its application in a cell-based competitive-binding assay.
The results suggest a common binding site on beta-tubulin for RH-4032, pronamide, zarilamide, and chlorpropham, which is distinct from the binding site(s) for trifluralin and amiprophosmethyl. Expand

Assays for inhibition of spore adhesion in 96-well microtiter plates by using sulforhodamine B staining to quantify the adherent spores provide a rapid, high-throughput alternative to traditional spore germination assays and may be applicable to other fungi. Expand
Effects of organic matter removal, soil compaction and vegetation control on 10th year biomass and foliar nutrition: LTSP continent-wide comparisons
We examined 10th year above-ground planted tree and total stand biomass, and planted tree foliar N and P concentrations across gradients in soil disturbance at 45 North American Long-Term Soil… Expand
RH-7281: a novel fungicide for control of downy mildew and late blight
Antifungal properties of taxol and various analogues
The antimitotic agent taxol was tested for toxicity towards fungi from different taxonomic groups and found to be particularly active against oomycete fungi. In germinating zoospore cysts of the… Expand
Identification of ceramide-phosphorylethanolamine in Oomycete plant pathogens: Pythium ultimum, phytophthora infestans, and Phytophthora capsici
Cellular lipids were extracted from three species of Oomycete plant pathogens (Pythium ultimum, Phytophthora infestans, and Ph. capsici) and analyzed via normal-phase high-performance liquid… Expand
Changes in glycosidase activity and their relationship to fungal colonization during infection of tomato by Verticillium albo-atrum
Fungal colonization throughout susceptible plants exceeded that in resistant plants and increases in glycosidase activity in different parts of infected plants were largely correlated with the distribution of the pathogen. Expand
