| pine nuts: the mycobiota and potential mycotoxins. | the mycobiota of pine nuts was investigated. in total, 1832 fungi belonging to 31 species and 15 genera (ascomycota, 2; zygomycota, 3; mitosporic fungi, 10) could be isolated. cladosporium spp. dominated the mycobiota with 685 isolations followed by phoma macrostoma with 351 isolations. overall, 16 potentially mycotoxigenic species were present on pine nuts. | 2001 | 11400738 |
| the macrocidins: novel cyclic tetramic acids with herbicidal activity produced by phoma macrostoma. | field isolates of phoma macrostoma were obtained from diseased canada thistle growing in several geographically diverse regions. bleaching and chlorotic symptoms were present on the infected plants. the isolates grown in liquid culture were found to produce phytotoxic metabolites which also caused bleaching when applied foliarly to several broadleaf species. bioassay-directed isolation led to the discovery of macrocidins a and b, the first representatives of a new family of cyclic tetramic acids ... | 2003 | 14695796 |
| molecular and genetic analyses of geographic variation in isolates of phoma macrostoma used for biological weed control. | molecular and genetic approaches were used to evaluate the genetic relatedness among isolates of the fungus phoma macrostoma montagne originating from canada and europe and to other species in the genus phoma. distinct differences were observed in genetic variation among nine species of the genus phoma. randomly amplified polymorphic dna (rapd) revealed the presence of intraspecific genetic variation among the isolates of p. macrostoma, with the isolates being used for biological weed control be ... | 2005 | 16392250 |
| the biotransformation of aromatic amino acids by phoma macrostoma. | a search for natural products produced in fermentation cultures of a strain of phoma macrostoma led to the identification of tyrosol as the major metabolite produced by this organism. the addition of the amino acid tyrosine to growing fermentation cultures of p. macrostoma resulted in an increase in the production of tyrosol. it was subsequently determined that this strain of p. macrostoma was also capable of the biotransformation of other amino acids into similar alcohols. | 2010 | 20184027 |
