Phylogeny and genetic diversity of Fusarium graminearum species complex associated with Fusarium head blight of wheat in Moghan plain (Iran)
Thirty-seven isolates of Fusarium graminearum species complexobtained from wheat heads with Fusarium head blight symptoms were selected and used for phylogenetic studies. They were collected from different localities of Moghan plain (Ardebil province, Iran). Partial sequences of translation elongation factor 1-alpha (TEF), putative reductase (RED) and UTP-ammonia ligase (URA) genes were amplifi...
متن کاملoccurrence of deoxynivalenol producing isolates of fusarium graminearum species complex associated with head blight of wheat in moghan area
the severe epidemics of fusarium head blight (fhb) as a devastating disease of cereal crops has occurred on wheat in north and northwest iran in recent years. the in vitro production of deoxynivalenol (don) was qualitatively evaluated in 41 fusarium isolates collected from wheat heads associated with the scab disease, in moghan area/northwest iran. infected wheat heads were collected during 200...
متن کاملIdentification of Fusarium species associated with Fusarium head blight of wheat in the North of Iran and phylogenetic analysis of the dominant species
In order to determine the causal agents of Fusarium head blight, during 2015–16, wheat heads with disease symptom were collected from 10 and six main wheat production areas of Golestan and Mazandaran provinces (N Iran), respectively. A total of 431 Fusarium isolates were obtained belonging to nine Fusarium species based on their morphological characteristics. Fusarium graminearum species comple...
متن کاملGenetic diversity of Fusarium graminearum sensu lato isolates from wheat associated with Fusarium Head Blight in diverse geographic locations of Argentina.
Fusarium Head Blight is an important wheat disease in the Argentine Pampas region, being Fusarium graminearum the predominant pathogen. DNA polymorphism of the isolates was analyzed by IGS-RFLP and ISSR. IGS-RFLP and ISSR profiling were carried out using six endonucleases and eight primers, respectively. IGS-RFLP yielded 41 bands, 30 of which were polymorphic while ISSR produced 87 bands with 4...
متن کاملPost-anthesis moisture increased Fusarium head blight and deoxynivalenol levels in North Carolina winter wheat.
ABSTRACT Current models for forecasting Fusarium head blight (FHB) and deoxynivalenol (DON) levels in wheat are based on weather near anthesis, and breeding for resistance to FHB pathogens often relies on irrigation before and shortly after anthesis to encourage disease development. The effects of post-anthesis environmental conditions on FHB are poorly understood. We performed a field experime...
