[ 1 ] - Identification of some fungi accompanying the scab symptoms in Iran

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...

[ 2 ] - Aspergillus medius, a new record to the mycobiota of Iran

During isolation of Venturia inaequalis (Cooke) G. Winter from apple leaves and fruits in the laboratory, some fungi appeared as culture contaminants. From these, an isolate was identified as Aspergillus medius R. Meissn. (teleomorph known as Eurotium medium C.F.W. Meissn.), based on morphological and molecular data (sequences of ITS rDNA).

[ 3 ] - تنوع و ساختار ژنتیکی جمعیت‌های قارچ Venturia inaequalis روی رقم‌های مختلف سیب در شمال ایران

بیماری لکۀ سیاه سیب مهم‌ترین بیماری اقتصادی این محصول است که سالیانه باعث همه‌گیری (اپیدمی)­هایی در نقاط مختلف جهان می­شود. این بیماری سالیانه باعث خسارت­های کمی و کیفی در مناطق مختلف کاشت سیب­ در کشور می­شود. در این مطالعه، تنوع و ساختار ژنتیکی جمعیت­های قارچ Venturia inaequalis روی رقم‌های مختلف سیب با استفاده از 18 نشانگر ریز ماهواره بررسی شد. تعداد 51 جدایۀ حاصل از نمونه­های برگ و میوۀ آلود...

[ 4 ] - First record of Epicoccum andropogonis growing on Paspalum dilatatum ergot in Iran

Paspalum dilatatum spikelets with ergot symptoms were collected from Rice Research Institute of Iran in Rasht, Guilan province during the fall of 2018. Ergot symptoms usually are caused by different Claviceps species on grasses. Sclerotia of ergot were globular in shape, black in color and irregularly roughened on the surface that resembles a brain. Different fungi were isolat...

[ 5 ] - The biocontrol potential of Pseudomonas fluorescens against Macrophomina phaseolina and estimating the total phenol compounds of bean roots

Charcoal rot caused by Macrophomina phaseolina is one of the most important soil borne diseases with a broad host range including bean, which annually brings a significant damage to this plant. Biological control of charcoal rot is very important because its chemical control harms the environment, microflora and soil fertility. Chemical control of charcoal rot is also difficult and sometimes in...
