Identification of Fusarium Species in Lorestan Province by Internal Transcribed Spacer Intergenic Area

Due to importance of poaceae plants in Zagros zone, these crops allocated frequent cultivated crops in most fields of this area. Among different microorganisms, Fusarium species are one of the important pathogens in these crops. During 2015-2016, to determine Fusarium species associated with root and crown of poaceae crops in Lorestan province, crop and non-crop plants in cereal fields and rangelands of Lorestan were collected. Sampling was conducted from plants with crown and root rot symptoms or with color changing of this area, and desired agent was isolated by selective media. Isolates were identified by morphology and identification keys, and sequencing of Internal Transcribed Spacer. In this study, 13 Fusarium species were identified as follows: F. acuminatum, F. avenaceum, F. crookwellense, F. culmorum, F. equiseti, F. ensiforme, F. falciforme, F. fujikuroi, F. longipes, F. nygamai, F. proliferatum, F. reticulatum, F. scirpi, F. solani, and F. tricinctum. Results showed that F. proliferatum is most frequent in this province. F. ensiforme is reported for the first time from Iran and it is new for Iran flora. Also this is the first report of F. falciforme from wheat root in Iran.
