| isolation and purification of canadaphore, a siderophore produced by helminthosporium carbonum. | a new siderophore was isolated and purified from the spent growth medium of the fungus helminthosporium carbonum by solvent extraction and reverse phase high pressure liquid chromatography. this new molecule has been assigned the name canadaphore. canadaphore was detected in culture filtrates after 15 days of growth and production was maximal after growth of h. carbonum to maximal stationary phase in modified fries basal medium. production of canadaphore was completely suppressed when the organi ... | 1985 | 3839125 |
| fungicidal action and structure correlation of monosubstituted phenyl isothiocyanates. | the fungicidal activity of 10 monosubstituted phenyl isothiocyanates was observed with four plant pathogens. the ortho- and meta-substituted derivatives possessed a fair activity while the para-substituted ones proved to be highly fungicidal when compared to the control agrosan gn. | 1985 | 4029817 |
| evidence for the presence of the toxin-binding protein on the plasma membrane of sugarcane cells. | helminthosporoside is a host-specific toxin produced by helminthosporium sacchari, both in culture and in infected sugarcane tissue. the susceptibility of any given clone of sugarcane to disease is invariably associated with the presence of a toxin-binding protein. this report presents evidence for the presence of the toxin-binding protein on the plasma membrane of the plant cell. this evidence includes, among others: (1) the protection of susceptible plant tissues by prior treatment with antise ... | 1974 | 4208550 |

| studies of the toxicity of helminthosporium maydis. | isolates of helminthosporium maydis from blighted corn were tested for toxicity in mice, rats, swine, rabbits, microorganisms, and tissue culture. extracts of grains, mycelia, and culture supernatant fluids killed mice on intraperitoneal (ip) injection, but were nontoxic on administration by mouth to swine. the toxin was partially purified and appears to be a glycophospholipid. histopathological examination revealed that the toxin acted as a severe irritant on ip injection, causing death in labo ... | 1972 | 5063202 |
