ABSTRACT Background Fungal endophytes occur ubiquitously in plants and are being increasingly studied for their ability to support plant health protect the host from diseases. Using disease control provides potential advantages compared other biocontrol agents since they colonise internally thereby stay protected environmental stresses fluctuations. A thorough understanding of mechanisms is required mutualistic association with plants; both optimise efficacy registration as protection...
Clonostachys rosea is a mycoparasitic fungus that can control several important plant diseases. Here, we report on the genome sequencing of C. and comparative analysis, in order to resolve phylogenetic placement study evolution mycoparasitism as fungal lifestyle. The estimated 58.3 Mb, contains 14,268 predicted genes. A phylogenomic analysis shows clusters sister taxon pathogenic Fusarium species, with mycoparasitic/saprotrophic Trichoderma species an ancestral position. gene family reveals...
Abstract Application of 3.6 mm silicon (Si+) to the rose (Rosa hybrida) cultivar Smart increased concentration antimicrobial phenolic acids and flavonoids in response infection by powdery mildew (Podosphaera pannosa). Simultaneously, expression genes coding for key enzymes phenylpropanoid pathway (phenylalanine ammonia lyase, cinnamyl alcohol dehydrogenase, chalcone synthase) was up-regulated. The increase compounds correlated with a 46% reduction disease severity compared inoculated leaves...
Fusarium head blight (FHB) is a major disease in wheat and other cereal crops. Biological control promising alternative for of this as current options are not efficient. Fungal endophytes could represent new source biological agents since they colonise plant tissues asymptomatically whilst sharing the same niche pathogens. Here, we show that healthy spikes leaves collected areas with high FHB incidence harbour fungal isolates reduce severity pathogen biomass inside spikes. We employed an...
Fungi living inside plants affect many aspects of plant health, but little is known about how genotype influences the fungal endophytic microbiome. However, a deeper understanding interactions between and biotic abiotic environment in shaping microbiome significance for modern agriculture, with implications disease management, breeding development biocontrol agents. For this purpose, we analysed wheat from seed to seeds studied different potential sources inoculum contributed We conducted...
Fusarium head blight (FHB) is a devastating disease of wheat heads. It caused by several species from the genus Fusarium. Several endophytic fungi also colonize spikes asymptomatically. Pathogenic and commensal share compete for same niche thereby influence plant performance. Understanding natural dynamics fungal community how pre-established react to pathogen attack can provide useful information on biology potential use some these organisms in control strategies. Fungal composition was...
Abstract Small cereals such as wheat, barley, and oat are staple food that directly (food) indirectly (feed) sustain large populations globally. However, their production is increasingly threatened by both abiotic biotic stresses. Biotic stresses, primarily caused plant pathogen fungi, bacteria, oomycota viruses responsible for nearly half of the annual crop losses. Many pathogens produce mycotoxins, which contaminate crops pose significant risks affecting human health. Fusarium spp.,...
ABSTRACT An ecological approach was used to select fungal antagonists effective against the seedborne pathogens Alternaria dauci and A. radicina on carrot. Twenty-five 105 isolates originating from cereal carrot habitats were screened in planta, respectively. Irrespective of isolate origin, belonging Clonostachys rosea controlled pre- postemergence death caused by as effectively fungicide iprodione. Isolate IK726 C. biopriming a seed lot with 29% 11% (highly infected), 4% 7% (low infection)....
Powdery mildew, caused by Podosphaera pannosa, is a very common disease in greenhouse potted roses, resulting poor marketing value and hence economic losses. Alternatives to chemical control are necessary, therefore the ability of silicon (Si) applied roots was investigated, as well mechanisms behind observed reductions. Four genotypes miniature roses representing different genetic backgrounds susceptibility were studied. Plants watered with nutrient solution containing either 3·6 m Si (100...
BACKGROUND Crops are often prone to both insect herbivory and disease, which necessitate multiple control measures. Ideally, an efficacious biological agent must adequately the target organism not be inhibited by other agents when applied simultaneously. Wheat seeds infected with plant pathogen Fusarium culmorum were treated Metarhizium brunneum or M. flavoviride Clonostachys rosea individually in combination, expectation root-feeding insects pathogen. Emerging roots evaluated for disease...
Entomopathogenic fungi (EPF) can display a plant-associated lifestyle as endophytes. Seed application of EPF affect insect herbivory above ground, but the mechanisms behind this are not documented. Here we applied three isolates, Beauveria bassiana, Metarhizium brunneum and M. robertsii, seed inoculation wheat bean, evaluated effects on population growth aphids, Rhopalosiphum padi Aphis fabae, respectively. In bean leaves, quantified benzoxazinoids flavonoids, respectively, in response to...
Little is known about the influence of host genotype and phytohormones on composition fungal endophytic communities. We investigated structure communities tomato roots by amplicon sequencing ITS1 region combined this approach with isolation functional characterization isolates. A significant effect dominant species was found comparing cultivars Castlemart UC82B and, surprisingly, root pathogens were among most abundant taxa. In contrast, smaller changes in relative abundance mutants impaired...

Control of seedling diseases is a major priority in many crop systems. Seed treatments that induce systemic resistance after emergence may be an ideal way to provide protection against disease during the establishment crop. CGA 245704, chemical activator acquired resistance, was tested as seed treatment two Brassica with contrasting infection biologies, airborne downy mildew pathogen, Peronospora parasitica, and soilborne fungus, Rhizoctonia solani. Seeds spp. were either imbibed various...
