the genus phaeoacremonium is associated with decline disease of woody plants and with human infections. members of this genus have broad host range and wide geographical distribution. during 2010, ten isolates of phaeoacremonium were recovered from vascular tissues of persimmon (diospyros kaki) trees, showing decline symptoms in shiraz city. anamorphic characteristics such as, conidiophore morp...

Novel cry genes are potential candidates for resistance management strategies, due to their different structures and modes of action. Therefore, it is desirable to clone and express novel cry genes from several new isolates of Bacillus thuringiensis (Bt). In the present study, 28 Bt strains were characterized at morphological and molecular level. All these strains are Gram positive, endospore f...

During the study on endophytic fungi of stone fruits including apricot, peach and nectarine in W Azarbaijan (NW Iran), a large number of isolates with Alternaria characteristics were isolated from different parts of these plants and studied taxonomically. Isolation was made based on endophytic fungal isolation method and following surface sterilization procedure. From 100 different plant sample...

Phytophthora capsici from seven provinces of China were investigated for their mating type, hyphal growth, zoospore production, and virulence. All of the morphological characteristics and the results of polymerase chain reaction confirmed that these isolates were indeed Phytophthora capsici. The test of mating type showed that the mating types of 19 representative isolates from China varied. Th...

diseased samples with root rot symptoms were collected from different sugar beet growing areas. from rotted roots, 20 fungal isolates were identified as fusarium solani based on morphological characteristics .pathogenecity of the isolates was studied in in vitro condition on sugar beet roots. the results showed pathogenic variability among the isolates. cluster analysis divided the isolates int...

Botrytis cinerea is an important pathogen that causes diseases in ornamental crops. In presentresearch several greenhouses of roses located in central region of Iran were surveyed toidentify the Botrytis cinerea. A total of 80 isolates were collected from rose greenhouses incentral region of Iran. Morphological identification was based on characters such asconidiophore and conidial length. Acco...

Seven endophytic bacterial isolates were finally recovered from native sugarcane varieties at hilly areas namely Berinag, Champawat and Didihat of Uttarakhand state in northern Himalayan region. New isolates and two standard cultures-Azospirillum brasilense and Gluconacetobacter diazotrophicus, were evaluated for their morphological, biochemical and molecular characteristics. Morphologically al...
