| survey of mycoflora and mycotoxins of some dried fruits in egypt. | fifty-five species and two varieties appertaing to 23 genera were collected and identified from 4 samples of dried fig and 3 dried samples of each of apricot, plum and raisin. forty-nine species and two varieties belonging to 20 genera were isolated on 1% glucose-czapek's while 31 species and one variety belonging to 16 genera were isolated on 40% sucrose-czapek's agar medium at 28 +/- 2 degrees c. penicillium, aspergillus and cladosporium were the common genera on the two types of media used. a ... | 1993 | 8229671 |
| herbarulide, a ketodivinyllactone steroid with an unprecedented homo-6-oxaergostane skeleton from the endophytic fungus pleospora herbarum1 | the novel ketodivinyllactonic steroid, herbarulide (1), deviating from the brassinosteroids in the position of the oxygen, was isolated from the endophytic fungus pleospora herbarum. the structure was determined by extensive nmr studies, including particularly hmqc and hmbc experiments. | 1999 | 10217727 |
| characterization of fungal 17beta-hydroxysteroid dehydrogenases. | to promote understanding of the evolution of the steroid hormone signalling and hydroxysteroid dehydrogenases (hsds), comparative characterization of fungal 17beta-hsds was performed. constitutive 17beta-hsd activity was determined in cytosols of the fungi: cochliobolus lunatus, pleospora herbarum, fusarium lini, trichoderma viride, mucor spinosus, rhizopus nigricans and pleurotus ostreatus. the reaction equilibrium in all species except p. ostreatus was shifted towards reduction. the preferenti ... | 2000 | 11126752 |
| surveys of microfungi in a former industrial area in duisburg-nord. | one hundred and forty microfungi (ascomycetes and deuteromycetes) were collected in the "landschaftspark duisburg-nord" located in north rhine-westphalia. new hosts for rarely found fungi are recorded for the first time. new for germany are massaria inquinans (tode) de not. and nitschkia grevillei (rhem) nannf. on acer pseudoplatanus l., pirottaea nigrostriata graddon on artemisia vulgaris l., ceratopycnis clematidis höhn. on clematis vitalba l., dasyscyphus aff. humuli (w. phillips) dennis on h ... | 2002 | 12701427 |
| restriction mapping of the igs region in alternaria spp. reveals variable and conserved domains. | accurate identification of alternaria spp. is dependent upon the production of diagnostic morphological characters under defined cultural conditions and the proper assessment of character variation. this process is often compromised by variation in laboratory facilities and technical expertise. to assist taxon identification and phylogenetic studies, restriction site information from the intergenic spacer (igs) region of nuclear rdna was evaluated. restriction maps were constructed from 15 speci ... | 2005 | 15736866 |
| mycodiversity on a dead stem of the giant hogweed--heracleum mantegazzianum sommer et levier. | during our investigations on microfungi in the ruhr area we were able to find the remarkable mycodiversity of different genera and species on dead stems of heracleum mantegazzianum, a neophyt for the european flora. altemaria alternata (fr.fr.) keissl., camarosporium spec., cladosporium herbarum (pers.) link, colletotrichum dematium (pers. ex fr.) gove, dactylella armandii yadv., dasyscyphus mollissimus (lasch.) dennis, dendryphion comosum wallr., endophragmia hyalosperma (corda) morgan-jones & ... | 2004 | 15756828 |
| the family pleosporaceae: intergeneric relationships and phylogenetic perspectives based on sequence analyses of partial 28s rdna. | the pleosporaceae is an important loculoascomycete family. there has been disagreement, however, regarding the taxonomic placement of many genera within this family. this study investigates phylogenetic relationships among the genera cochliobolus, kirschsteiniothelia, leptosphaerulina, macroventuria, pleospora, pyrenophora, and wettsteinina. partial 28s rdna sequences from taxa within these genera were analyzed with maximum parsimony, likelihood and bayesian methods. cochliobolus can be segregat ... | 2006 | 17139850 |
| remarkable microfungi from oaxaca (mexico) of acacia species. | in the state of oaxaca (mexico, 10 km north-west of puerto escondido 15 degrees 55' n, 97 degrees 09' w) we were able to collect some microfungi living as parasites or saprophytes on acacia species, some of them are causing attention for oaxaca. many belong to the deuteromycotina (hyphomycetes, coelomycetes) and ascomycotina. on a. hindsii: calonectria pseudopeziza (desm.) sacc., hypoxylon truncatum (schwein. fr.) j.h. miller, epicoccum nigrum link., zygosporium gibbum (sacc., m. roussau & e. bo ... | 2007 | 18396821 |
| pleospora species with stemphylium anamorphs: a four locus phylogeny resolves new lineages yet does not distinguish among species in the pleospora herbarum clade. | stemphylium is a genus of plant pathogens and saprobes in the pleosporaceae (pleosporales, dothideomycetes, ascomycetes). the teleomorphs of stemphylium, where known, are in pleospora, with pleospora herbarum as the type. the goal of this study was to present a rigorous phylogenetic analysis of the relationships among stemphylium isolates with particular emphasis on species delimitation in the p. herbarum clade, on possible new species and on the relationship of clades to cultures from type spec ... | 2009 | 19537206 |
| decorospora, a new genus for the marine ascomycete pleospora gaudefroyi. | in this paper, we investigate the phylogenetic placement of pleospora gaudefroyi using partial ssu as well as its ribosomal dna sequences. both ssu and its data sets agreed in the placement of p. gaudefroyi. parsimony and neighbor-joining analyses of each data set placed p. gaudefroyi within the pleosporaceae with 100% bootstrap support. pleospora gaudefroyi was sister taxon in the pleosporaceae represented by alternaria alternata, cochliobolus sativus, pleospora herbarum, pyrenophora tritici-re ... | 2002 | 21156538 |
