| etiology of apple sooty blotch disease in north carolina. | abstract sooty blotch disease of apples (malus x domestica), previously attributed to the fungus gloeodes pomigena, was shown to be a disease complex caused by fungi previously considered mycelial types of g. pomigena. peltaster fructicola and geastrumia polystigmatis were associated with the ramose mycelial type. a fungus similar to p. fructicola, but with smaller pycnothyria and conidia, was associated with the punctate mycelial type. the diffuse fuliginous mycelial type was caused by leptodon ... | 1997 | 18945159 |
| response of two fungi in the apple sooty blotch complex to temperature and relative humidity. | abstract peltaster fructicola and leptodontium elatius, two of the causal fungi of apple sooty blotch, responded differently to temperature and relative humidity in vitro. conidia of l. elatius germinated from 12 to 32 degrees c at relative humidities >/=97%, whereas conidia of p. fructicola germinated from 12 to 24 degrees c at relative humidities >/=95%. germination of conidia of l. elatius was optimum at 32 degrees c and 99% relative humidity compared with 24 degrees c and 97 or 99% relative ... | 2000 | 18944585 |
| zaragozic acids: a family of fungal metabolites that are picomolar competitive inhibitors of squalene synthase. | three closely related fungal metabolites, zaragozic acids a, b, and c, that are potent inhibitors of squalene synthase have been isolated and characterized. zaragozic acids a, b, and c were produced from an unidentified sterile fungal culture, sporormiella intermedia, and leptodontium elatius, respectively. the structures of the zaragozic acids and their trimethyl esters were determined by a combination of physical and chemical techniques. the zaragozic acids are characterized by a novel 2,8-dio ... | 1993 | 8419946 |
