یکی از مهم‌ترین مدهای حمل‌ونقل عمومی شبکة مترو است که تأثیر بسزایی در کاهش ترافیک و آلودگی هوا دارد. ازدیگرسو، با توجه به هزینه‌های سرسام‌آور راه‌اندازی مترو، توسعة مرحله‌به‌مرحله بهره‌برداری یک خط اجرای خطوط دیگر به‌دست مدیران شهری مورد است. بنابراین، هدف این تحقیق بررسی میزان دسترسی متروی اصفهان افق 1410، رویکرد عدالت مکانی، دو جنبة افقی عمودی پنج طبقة اجتماعی، استفاده شاخص‌های ضریب جینی، منح...

Aspergillus flavus is a cosmopolitan fungus able to respond to external stimuli and to shift both its trophic behaviour and the production of secondary metabolites, including that of the carcinogen aflatoxin (AF). To better understand the adaptability of this fungus, we examined genetic and phenotypic responses within the fungus when grown under four conditions that mimic different ecological n...

Estuary basin is a fertile area which has important role for sustaining many organisms from estuary and sea. Mould and other saprobic microorganisms have important role to decomposing organic material in estuary water. A study on diversity and abundance of mould inhabiting Muara Layang estuary sediment, Bangka Belitung Islands has not been conducted before. The objective of this study is to inv...

Nonribosomal peptides, made by nonribosomal peptide synthetases, have diverse biological activities, including roles as fungal virulence effectors. Inspection of the genome of Cochliobolus heterostrophus, a fungal pathogen of maize and a member of a genus noted for secondary metabolite production, revealed eight multimodular nonribosomal peptide synthase (NPS) genes and three monomodular NPS-li...

Fungus-derived indole-3-acetic acid (IAA), which is involved in development of ectomycorrhiza, affects both partners, i.e., the tree and the fungus. The biosynthesis pathway, excretion from fungal hyphae, the induction of branching in fungal cultures, and enhanced Hartig net formation in mycorrhiza were shown. Gene expression studies, incorporation of labeled compounds into IAA, heterologous ex...

BACKGROUND Coccidioides spp. is the ethiological agent of coccidioidomycosis, an infection that can be fatal. Its diagnosis is complicated, due to that it shares clinical and histopathological characteristics with other pulmonary mycoses. Coccidioides spp. is a dimorphic fungus and, in its saprobic phase, grows as a mycelium, forming a large amount of arthroconidia. In susceptible persons, arth...

This work describes the distribution and diversity of fungal endophytes associated with leaves of Colobanthus quitensis, a dicotyledonous plant that lives in Antarctica. A total of 188 fungal isolates were obtained from six different sites located across a 25.5-km transect through Admiralty Bay, at King George Island. The ITS1-5.8S-ITS2 nuclear ribosomal gene was sequenced and the endophytic fu...

The Alternaria and Ulocladium species reported from humans are studied taxonomically using rDNA internal transcribed spacer (ITS) sequence data. The ITS variability within the genus is relatively limited. The two most important, longicatenate species, Alternaria alternata and A. infectoria, clearly differ in their ITS domains, due to a 26-bp insert in ITS1 of the latter species. A number of tax...

The genus Cladosporium (Cladosporiaceae, Dothideomycetes), which represents one of the largest genera of dematiaceous hyphomycetes, has been intensively investigated during the past decade. In the process, three major species complexes (C. cladosporioides, C. herbarum and C. sphaerospermum) were resolved based on morphology and DNA phylogeny, and a monographic revision of the genus (s. lat.) pu...
