some fungal species were isolated from scab or scab-like symptoms on leaves of various plant hosts in iran. some of them isolated from apple and pear leaves were investigated in the present study. the isolates were identified based on the morphological and cultural characteristics. on the other hand, for molecular identification and phylogenetic analyses were carried out based on the sequence o...

conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. these tests often need several days or weeks to complete and are frequentlyunspecific. molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. the rolling circleamplification app...

seedless barberry (berberis vulgaris l. var. asperma) is one of the few crops that is only cultivated in eastern parts of iran. as a new crop there has not been any study to identify phylogenetic relationships of this plant with other related species existing in iran. in this study, amplification fragment length polymorphism (aflp) markers based on four selected primer combinations (ecori/tru1i...

Background and Purpose: Soil is the main habitat of saprophytic and pathogenic fungi. Mucormycetes are one of the most parts of soil fungi and certain members are among opportunistic fungi and can cause systemic fungal infections in immunocompromised patients. The majority of human and animal infections are caused by members of the genera Rhizopus, Mucor, Rhizomucor, Lichtheimia (Absidia), Cunn...

thrips tabaci lindeman is an extensively distributed pest insect in many areas that affects plants through direct feeding and at the same time, it makes damage as a vector of different viruses. as a basic first step to control pests is authentic identification, but the inability to determine morphological characters of thrips species makes this process very difficult. for creating an identifica...

during 2004–2007 various own rooted vineyards were inspected to study the fungi associated with vine trunk diseases in iran. samples from declining vines showing yellowing and reduced growth and different symptoms in wood, including browning of the wood, necrosis, brown and black streaking and white rot were collected. fungal isolations were made from affected tissues onto malt extract agar (me...

Molecular and Morphological identification of the genus Dineutus MacLeay, 1825 (Coleoptera, Gyrinidae) from Eastern Ghats, India

Background: Classical bacteriological detection of Brucella species from food, and environment is routinely carried out based on morphological and biochemical characteristics. However, for increasing specificity and sensitivity of species identification methods, development of a molecular assay is necessary that was main aim of this study. Methods: Panel of some reference strains belonging to ...
