ABSTRACT Fusarium fungi, including F. culmorum, cause seedling blight, foot rot, and head blight diseases of cereals, resulting in yield loss. In a screen for potential disease control organisms and agents, Pseudomonas fluorescens strains MKB 100 and MKB 249, P. frederiksbergensis strain 202, Pseudomonas sp. strain MKB 158, and chitosan all significantly(More)
The mycotoxin deoxynivalenol (DON) acts as a disease virulence factor for Fusarium fungi, and tolerance of DON enhances wheat resistance to Fusarium head blight (FHB) disease. Two variants of an ATP-binding cassette (ABC) family C transporter gene were cloned from DON-treated wheat mRNA, namely TaABCC3.1 and TaABCC3.2. These represent two of three putative(More)
Microbial bioprocessing of lignocellulose to bioethanol still poses challenges in terms of substrate catabolism. A targeted evolution-based study was undertaken to determine if inter-strain microbial variability could be exploited for bioprocessing of lignocellulose to bioethanol. The microorganism studied was Fusarium oxysporum because of its capacity to(More)
Strains of non-pathogenic pseudomonad bacteria, can elicit host defence responses against pathogenic microorganisms. Pseudomonas fluorescens strain MKB158 can protect cereals from pathogenesis by Fusarium fungi, including Fusarium head blight which is an economically important disease due to its association with both yield loss and mycotoxin contamination(More)
The Fusarium mycotoxin deoxynivalenol (DON) facilitates fungal spread within wheat tissue and the development of Fusarium head blight disease. The ability of wheat spikelets to resist DON-induced bleaching is genotype-dependent. In wheat cultivar (cv.) CM82036 DON resistance is associated with a quantitative trait locus, Fhb1, located on the short arm of(More)
BACKGROUND The quest for developing silk fibroin as a biomaterial for drug release systems continues to draw research interest owing to its impressive mechanical properties as well as biocompatibility and biodegradability. The aim of this study is to develop low-temperature O2 plasma-treated muga (Antheraea assama) silk fibroin (AASF) yarn impregnated with(More)
Fusarium pathogens are among the most damaging pathogens of cereals. These pathogens have the ability to attack the roots, seedlings, and flowering heads of barley and wheat plants with disease, resulting in yield loss and head blight disease and also resulting in the contamination of grain with mycotoxins harmful to human and animal health. There is(More)
The Fusarium mycotoxin deoxynivalenol (DON) can cause cell death in wheat (Triticum aestivum), but can also reduce the level of cell death caused by heat shock in Arabidopsis (Arabidopsis thaliana) cell cultures. We show that 10 μg mL(-1) DON does not cause cell death in Arabidopsis cell cultures, and its ability to retard heat-induced cell death is light(More)
Fusarium oxysporum f. sp. pisi (van Hall) Snyder & Hansen is an important pathogen of pea that causes wilt. The present study was carried out to evaluate the efficacy of rhamnolipid biosurfactant produced by newly isolated Pseudomonas aeruginosa strain SS14 as an antifungal agent against F. oxysporum f. sp. pisi in Pisum sativum L. The bacterial strain P.(More)
Fusarium oxysporum can convert straw to ethanol via consolidated bioprocessing (CBP)—a two-stage process that firstly involves aerobic saccharification and thereafter an oxygen-limiting fermentation phase. The efficacy of CBP is dependent upon the fungal strain used. Using suppression subtractive hybridisation (SSH), a total of 210 transcripts were(More)
