| properties of aspergillus tamarii, a. caelatus and related species from acidic tea field soils in japan. | fungi in aspergillus section flavi include both aflatoxin producers and non-producers. aspergillus caelatus is a recently described non-aflatoxigenic species in this section, which has some common characteristics with a. tamarii, such as yellowish brown color and double walled spores. in contrast to the morphological similarities, all of the a. caelatus isolates tested produced no cyclopiazonic acid whereas most isolates of a. tamarii produce this compound. there are six nucleotide differences t ... | 1998 | 10531683 |
| dna fingerprinting analysis of vegetative compatibility groups in aspergillus caelatus. | forty-three isolates of aspergillus caelatus, whose vegetative compatibility groups (vcgs) have been identified, were assessed by dna fingerprinting using a repetitive sequence dna probe (paf28) cloned from a. flavus. thirteen distinct dna fingerprint groups or genotypes were identified among the 43 isolates. twenty-four isolates belonging to vcg 1 produced identical dna fingerprints and included isolates from the united states and japan. four other dna fingerprint groups had multiple isolates s ... | 2005 | 16389958 |
| new stilbenoids from peanut ( arachis hypogaea ) seeds challenged by an aspergillus caelatus strain. | four new stilbene derivatives, termed arahypins, have been isolated from peanut seeds challenged by an aspergillus caelatus strain, along with two known stilbenoids that have not been previously reported in peanuts. the structures of these new putative phytoalexins were determined by analysis of nmr, ms, and uv data. together with other known peanut stilbenoids that were also produced in the challenged seeds, these new compounds may play a defensive role against invasive fungi. | 2009 | 19063668 |
| new dimeric stilbenoids from fungal-challenged peanut ( arachis hypogaea) seeds. | the peanut plant can resist fungal attacks by producing stilbene-derived phytoalexins. once understood, such a natural phytoalexin-based mechanism of peanut resistance could be potentially manipulated to obtain fungal-resistant peanut breeding lines. several simple stilbenoid phytoalexins from peanuts have been reported. however, more complex stilbenoid derivatives such as those that have been reported from other sources and considered important factors in plant defense have not been found in pe ... | 2010 | 20020707 |
| pterocarpenes elicited by aspergillus caelatus in peanut (arachis hypogaea) seeds. | the substituted pterocarpenes named aracarpene-1 (1) and aracarpene-2 (2) were isolated from wounded peanut seeds challenged by a strain of aspergillus caelatus. the structures of these putative phytoalexins were determined by interpretation of nmr and ms data. the aracarpenes were investigated for their antifungal and antibacterial activities as well as antioxidant, anti-inflammatory, and cytotoxic activities in mammalian cells. aracarpene-2 demonstrated high antibacterial properties against te ... | 2010 | 21030054 |
| synnema and sclerotium production in aspergillus caelatus and the influence of substrate composition on their development in selected strains. | the ability of aspergillus caelatus, a species in aspergillus section flavi, to produce synnemata and sclerotia was investigated. forty-eight isolates of a. caelatus differed widely in their production of synnemata and sclerotia; 83% of the isolates produced varying numbers of synnemata and sclerotia, and 17% produced neither sclerotia nor synnemata. most strains produced synnemata and mostly sessile and few stipitate sclerotia on the same czapek agar (cza) plate. two strains of a. caelatus were ... | 2004 | 21148914 |
| plant-available inorganic nutrient levels are increased in rice-derived distillery effluents inoculated with microbes. | the purpose of this study was to assess the effects of microbes on plant-available inorganic nutrients and a phytohormone in rice-derived distillery effluents. | 2014 | 25040155 |
