Trichothecenes are the most common Fusarium toxins detected in grains and related products. Type A trichothecenes among mycotoxins of greatest concern to food feed safety due their high toxicity. Recently, two different trichothecene genotypes within species were reported. The available information showed that Tri1 Tri16 genes key determinants profiles T-2 DAS genotypes. In this review, polymor...

fusarium head blight (fhb) or wheat scab is one of the destructive diseases that cause considerable loss in grain quality in cereal cultivated around the worldwide due to the production of trichotecen mycotoxin in the panicle. type b trichothecenes including nivalenol (niv), deoxynivalenol (don), 3-acetyl deoxynivalenol (3-acdon) and 15-deoxynivalenol (15-acdon) are considered to be major toxin...

A total of 198 cereal samples (53 maize, 54 sorghum, 37 paddy and 54 wheat) were collected from 11 districts of Karnataka to understand the percent infection (PI), relative density (RD) and their frequency (Fr) caused by Fusarium spp. All samples were screened by agar plating method using MGA 2.5 agar media and incubated at 25 ± 2 °C for 3-5 days. The study revealed the association of 10 differ...

The aim of this study was to investigate the antifungal effects and molecular changes caused by Usnea longissima Ach. extracts against Fusarium greaminearum. In agar well diffusion assay, zone inhibition increased as concentration in both methanol acetone (1, 10, 20 50 mg/ml). terms bioactivities, 1 mg/ml active, while other concentrations were very active. At level, extract analyzed qPCR with ...

Fusarium graminearum sensu stricto causes Fusarium head blight (FHB) in wheat and barley, and contaminates grains with several trichothecene mycotoxins, causing destructive yield losses and economic impact in the United States. Recently, a F. graminearum strain collected from Minnesota (MN) was determined to produce a novel trichothecene toxin, called NX-2. In order to determine the spatial and...
