Fusarium head blight, one of the most destructive diseases of wheat (Triticum aestivum L.), results in significant economic losses from reduced grain yield and quality. In recent decades, the disease has been frequently recorded, especially under warm and wet climatic conditions. Genetic resistance has engaged plant breeders because the use of resistant cultivars is the most economical, effecti...

Resistance to Fusarium head blight in 32 winter triticale and 34 winter wheat accessions was evaluated. Triticale and wheat were sown in field experiments in two locations. At the time of flowering, heads were inoculated with three Fusarium culmorum isolates. Fusarium head blight index was scored and after the harvest percentage of Fusarium damaged kernels was assessed. Grain was analysed for t...

fusarium graminearum is causal agent of economically catastrophic disease of cereal fusarium head blight (fhb) around the world. in addition to causing a loss of yield, this fungus causes serious threats to humans and animals due to the contamination of grain with the trichothecene mycotoxin. tri101 gene, a fusarium spp. gene, encodes an enzyme that transfers an acetyl group to the c3 hydroxyl ...

(57) ABSTRACT Disclosed are methods of identifying subspecies of Crypto coccus flavescens and methods of treating or suppressing Fusarium head blight with the different Cryptococcus flave scens species. In particular, two genotypes, Genotypes A and B, were identified using the disclosed real time PCR tech nique. The following Cryptococcus flavescens strains were identified as being either Genot...

fusarium head blight (fhb) caused by fusarium graminearum is a serious disease of wheat (triticum aestivum l.), through which grain quality losses are induced by fungal trichotecene mycotoxins such as deoxynivalenol (don). a class of plasma membrane localized abc transporter proteins related to the yeast pdr5 (pleiotropic drug resistance5) efflux pump seems to be responsible for partial resista...

The toxic effects of the Fusarium graminearum trichothecene toxin deoxynivalenol were determined on ribosomes and leaf tissues of the fusarium head blight-resistant spring wheat cultivar Frontana and the susceptible spring wheat cultivar Casavant. The use of a poly-U-directed 14C-phenylalanine and deoxynivalenol ribosome-binding assays provided evidence of resistance to the protein-synthesis in...

Fusarium head blight is one of the most important and most common diseases of winter wheat. In order to better understanding this disease and to assess the correlations between different factors, 30 cultivars of this cereal were evaluated in a two-year period. Fusarium head blight resistance was evaluated and the concentration of trichothecene mycotoxins was analysed. Grain samples originated f...

good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. in this experiment this relation has been checked out. the morphological traits were included plant height, peduncle length and spike density. we used 28 spring wheat genotypes and 2 durum genotypes. there was sig...

Samples of grain from 40 New Zealand wheat and barley crops harvested in 2000 were assayed for Fusarium infection. Grain from all crops was infected, and Fusarium incidence ranged from 3 to 52% of grains infected, with a mean of 14%. Incidence of Fusarium was higher in spring wheat than in autumn wheat or spring barley. The highest level of infection (52% grains infected) was found in Otane whe...
