Abstract:

In order to explore biodiversity of Fusarium species associated with the inflorescences of poaceous weeds, heads and inflorescences were collected from wild grasses in Ardabil province (Iran). Fusarium species were isolated using general and selective media. Pure cultures were established using a single spore technique. The isolates were identified based on morphological and molecular data. Sequence data were generated for TEF-1α gene, following PCR amplifciation. The results revealed that several species of Fusarium are present on inflorescences of wild grasses in Ardabil province. Among the identified species, F. brachygibbosum, F. torulosum and F. cf. reticulatum var. negundis represent new records to the mycobiota of Iran. There is no description available for these taxa in Persian literature and references to the original descriptions are not easily accesible. Here we provide detailed descriptions for these taxa and discuss their morphology, phylogeny and ecology. This is the first study on biodiversity of Fusarium spp. associated with the inflorescences of wild poaceous grasses by using a combination of morphology and DNA sequence data.

Detection of the fumonisin-producing Fusarium fujikuroi species complex (FFSC) associated with wild grasses in Iran

In order to determine the fumonisin producingisolates of the Fusarium fujikuroi species complex (FFSC), associated with infected spikes, and ear rot of grass plants, we examined 78 samples collected from Kermanshah province, Iran. Based on morphological characters, twenty two isolates assigned to the FFSC and were identified as F. proliferatum (ten isolates), F. verticillioides (seven isolates)...

Morphological and phylogenic analysis of Fusarium species associated with vertical system of Orobanche spp.

Broomrapes (Orobanche spp.) are parasitic weeds and considered as a major limiting factor for the cultivation of various crops in many parts of the world. Due to the special biology of broomrape, including seed production, dispersal and longevity, the control of these species are often extremely difficult. Broomrape poses a serious threat to Iran’s agriculture; therefore exploring potential bio...

Morphological and molecular characterization of Oomycetes associated with root and crown rot of cucurbits in Kermanshah province, Iran

Pythium and Phytophthora are among the most well-known plant pathogens around the world that cause rotting of seeds, root, and crown, seedling death, and soft rot of fruits in contact with the soil. In this research, 347 isolates of these two genera and their close genus, Phytopythium were isolated from the cucurbits fields in Kermanshah province, Iran and examined in...

Fusarium species associated with medicinal plants of Lamiaceae and Asteraceae

The purpose of this study was to identify the Fusarium species associated with selected medicinal plant species of Lamiaceae and Asteraceae in Kerman, the second-largest province of Iran. The plants showing wilting/rotting symptoms as well as asymptomatic plants were collected from main medicinal plants reservoirs and production areas. Fusarium species were identified based on...

Three new species of Pseudocercospora for mycobiota of Iran

Several specimens belonging to the genus Pseudocercospora were collected from different localities of Mazandaran province (N Iran) during the 2011–12. All specimens were microscopically studied and identified. As the result Pseudocercospora abeliae (on Abelia grandiflora), P.rhamnaceicola (on Paliurus spina-christi) and P.sordida (on Campsis grandiflora) are newly recorded for Iran. Furthermore...

THREE NEW SPECIES OF TRICHODERMA FOR THE MYCOFLORA OF IRAN

Some 350 Trichoderma isolates were obtained from soil samples collected from different parts of Iran. Cultures were purified on 2% water agar by hyphal tip method prior to identification. Obtained isolates were identified using morphological features including colony characters (pigmentation and growth rate on PDA) and microscopic characters such as shape of conidiophores, shape and size of con...
