A Simple Method for the Assessment of Fusarium Head Blight Resistance in Korean Wheat Seedlings Inoculated with Fusarium graminearum
Fusarium head blight (FHB; scab) caused mainly by Fusarium graminearum is a devastating disease of wheat and barley around the world. FHB causes yield reductions and contamination of grain with trichothecene mycotoxins such as deoxynivalenol (DON) which are a major health concern for humans and animals. The objective of this research was to develop an easy seed or seedling inoculation assay, an...
متن کاملPhylogeny 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 کاملSoybean Pod Blight and Root Rot Caused by Lineages of the Fusarium graminearum and the Production of Mycotoxins
Queima da vagem e podridão de raízes da soja causadas por linhagens de Fusarium graminearum e produção de micotoxinas Amostras de sementes de soja (Glycine max) produzidas no Sul do Brasil estavam infetadas com Fusarium graminearum. Para determinar se membros desse complexo de espécies eram patogênicos à soja, seis isolados do fungo, originados de sementes soja, foram adicionados ao solo numa d...
متن کاملResistance to Fusarium head blight and seedling blight in wheat is associated with activation of a cytochrome p450 gene.
ABSTRACT One plant genotype displays a resistance phenotype at one development stage but a susceptible reaction to the same pathogen at another stage, which is referred to here as resistance inversion. In wheat, Fusarium head blight (FHB)-resistant cv. Sumai3 showed a Fusarium seedling blight (FSB)-susceptible reaction whereas FHB-susceptible cv. Annong8455 exhibited FSB resistance when challen...
متن کاملBacterial endophytes from wild maize suppress Fusarium graminearum in modern maize and inhibit mycotoxin accumulation
Wild maize (teosinte) has been reported to be less susceptible to pests than their modern maize (corn) relatives. Endophytes, defined as microbes that inhabit plants without causing disease, are known for their ability to antagonize plant pests and pathogens. We hypothesized that the wild relatives of modern maize may host endophytes that combat pathogens. Fusarium graminearum is the fungus tha...
