بهمنظور شناسایی عاملهای قارچی دخیل در سرخشکیدگی درختان کاج در شهر کرمانشاه، در فصلهای مختلف سالهای 1395-1394 از درختان کاج دارای نشانههای بیماری،نمونهبرداری و جداسازی قارچها صورت گرفت. در نتیجه 169 جدایۀ قارچی شامل گونههای مختلف جنس Aspergilusبا 41 جدایه (فراوانی 26/24 درصد)، گونههای مختلف جنس Peniciliumبا 25 جدایه (فراوانی 79/14 درصد)، Microsphaeropsis olivaceaبا 16 جدایه (فراوانی 46/...
© 2015 The Authors. doi: 10.2340/00015555-2091 Journal Compilation © 2015 Acta Dermato-Venereologica. ISSN 0001-5555 Coelomycetes are asexual fungi which produce their conidiospores within fruiting structures known as conidiomata. They are ubiquitous in soil and freshwater environments, and recognized as plant pathogens (1, 2). Although human infections with coelomycetous fungi are exceedingly ...
Seven compounds belonging to different structural skeletons were isolated from Microsphaeropsis olivacea grown in liquid and solid media. The enalin derivative 7-hydroxy-2,4-dimethyl-3(2H)-benzofuranone is reported for the first time, while additional spectroscopic information is provided for the acetates of botrallin and ulocladol. The activity of the isolated compounds was assessed towards th...
The generic concept of Phyllosticta has undergone substantial changes since its establishment in 1818. The existence of conidia with a mucilaginous sheath and an apical appendage is synapomorphic for Phyllosticta species, which has been shown in recent molecular phylogenetic studies. Thus a natural classification of Phyllosticta species should emphasize above morphological characters. Many name...
Fungal metabolites with an epi-oligothiadiketopiperazine structure, TAN-1496 A, C and E, were isolated from the culture broth of Microsphaeropsis sp. FL-16144. Their molecular formulas were determined to be C22H28N2O9S2, C22H28N2O9S3 and C22H28N2O9S4, respectively. Structures were determined by comparing the NMR data with those of known diketopiperazine antibiotics, sirodesmins. These metabolit...
