Cenococcum is a genus of ectomycorrhizal Ascomycota that has a broad host range and geographic distribution. It is not known to produce either meiotic or mitotic spores and is known to exist only in the form of hyphae, sclerotia and host-colonized ectomycorrhizal root tips. Due to its lack of sexual and asexual spores and reproductive structures, it has proven difficult to incorporate into trad...
Three new species, Cantharellus phasmatis, Cantharellus flavus and Cantharellus spectaculus, all previously considered Cantharellus cibarius, are described in this study. The circumscription of these three species from C. cibarius and other Cantharellus species is supported by morphological differences and nuclear DNA sequence data (nLSU, ITS, TEF1). All were found under Quercus spp. in a small...
The endophytic fungus strain 0248, isolated from garlic, was identified as Trichoderma brevicompactum based on morphological characteristics and the nucleotide sequences of ITS1-5.8S- ITS2 and tef1. The bioactive compound T2 was isolated from the culture extracts of this fungus by bioactivity-guided fractionation and identified as 4β-acetoxy-12,13- epoxy-Δ(9)-trichothecene (trichodermin) by spe...
Abstract Peppermint is an important medicinal plant, and it known for its essential oils phenolic acids. Verticillium wilt a vascular disease resulted from several spp. causing significant economic losses in peppermint cultivation. In this study, the fungus Gibellulopsis nigrescens (syn. ) was isolated symptomless plants during regular control of on Germany. A pure fungal culture prepared, DNA ...
During a diversity study of entomopathogenic fungi in an agricultural ecosystem, two were collected, isolated, and identified based on molecular phylogenetic analyses three nuclear loci (LSU, TEF1, RPB1) combined with morphological data. In this study, one novel species is described, Ophiocordyceps flavida, new record Pseudogibellula formicarum for Thailand. flavida morphologically resembles th...
بیماری میوه سبز مرکبات توسط باکتری سخت کشت candidatus liberobacter asiaticus ایجاد می شود که اولین بار در چین توصیف شده است و در سال 1919 با نام رسمی huanglongbing معرفی گردید. این بیماری یکی از پرخسارت ترین بیماری های مرکبات درجنوب شرقی آسیا، شبه قاره هند، آفریقای جنوبی و شبه جزیره عربستان است. این بیماری در سال 1386 از جنوب ایران گزارش گردید. برای درک مکانیسم مولکولی برهمکنش میزبان-پاتوژن از ...
objective(s): the aim of this study was to investigate the methylation status and mrna expression levels of p15, death-associated protein kinase (dapk), and suppressor of cytokine signaling-1 (socs1) genes in multiple myeloma (mm). materials and methods: the bone marrow samples of 54 mm patients were collected and the methylation status of the p15, dapk, and socs1 gene promoter regions was dete...
conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...
Phlebiopsis gigantea (Fr.) Jülich is a well-known generalist conifer wood saprobe and biocontrol fungus used in several world countries to prevent stump infection by tree pathogenic Heterobasidion fungal species. Previous studies have reported the presence of regional continental genetic differentiation host-specific fungi, but such for saprobes as P. has not been often studied or demonstrated....
Sympoventuriaceae ( Venturiales , Dothideomycetes ) comprises genera including saprophytes, endophytes, plant pathogens, as well important animal or human opportunistic pathogens with diverse ecologies and wide geographical distributions. Although the taxonomy of has been studied, generic boundaries within family remain poorly resolved due to lack type materials molecular data. To address this ...
