Abstract:

The term mycoparasitism applies strictly to those relationships in which one living fungus acts as a nutrient source for another, but fungicolous relationships may also be included in which nutrient exchange has not been shown. Fungicolous fungi have a constant but indeterminate association with another fungus, and it can be difficult to demonstrate a true parasitic relationship. Mycoparasitic relationships can be necrotrophic or biotrophic, and can be classified on the basis of the host–parasite interface as contact necrotrophs, invasive necrotrophs, haustorial biotrophs, intracellular biotro

Abstract:

Host specialization is common among parasitic fungi; however, there are examples when transitions in host specificity between disparately related hosts have occurred. Here, we examine the interkingdom host jump from insect pathogenicity and mycoparasitism in Tolypocladium. Previous phylogenetic inferences made using only a few genes and with poor support reconstructed an ancestral character state of insect pathogenesis, a transition to mycoparasitism, and reversions to insect pathogenesis. To further explore the directionality and genes underlying the transitions in host, we sequenced two addi

Abstract:

Mycoparasitic Trichoderma spp. act as potent biocontrol agents against a number of plant pathogenic fungi, whereupon the mycoparasitic attack includes host recognition followed by infection structure formation and secretion of lytic enzymes and antifungal metabolites leading to the host's death. Host-derived signals are suggested to be recognized by receptors located on the mycoparasite's cell surface eliciting an internal signal transduction cascade which results in the transcription of mycoparasitism-relevant genes. Heterotrimeric G proteins of fungi transmit signals originating from G-prote

Abstract:

Powdery mildews, ubiquitous obligate biotrophic plant pathogens, are often attacked in the field by mycoparasitic fungi belonging to the genus Ampelomyces. Some Ampelomyces strains are commercialized biocontrol agents of crop pathogenic powdery mildews. Using Agrobacterium tumefaciens-mediated transformation (ATMT), we produced stable Ampelomyces transformants that constitutively expressed green fluorescent protein (GFP) to (i) improve the visualization of the mildew–Ampelomyces interaction and (ii) decipher the environmental fate of Ampelomyces fungi before and after acting as a mycoparasite.

Abstract:

ABSTRACT Trichoderma species are used commercially as biocontrol agents against a number of phytopathogenic fungi due to their mycoparasitic characterisitics. The mycoparasitic response is induced when Trichoderma specifically recognizes the presence of the host fungus and transduces the host-derived signals to their respective regulatory targets. We made deletion mutants of the tga3 gene of Trichoderma atroviride, which encodes a novel G protein α subunit that belongs to subgroup III of fungal Gα proteins.

Abstract:

The antifungal mechanism of mycoparasitic fungi involves fungal cell wall degrading enzymes such as chitinases. Trichothecium roseum is an important mycoparasitic fungus with significant antifungal ability, but studies on chitinases of T. roseum were poor. Here, we report a novel chitinase cDNA isolated from T. roseum by PCR amplification based on conserved chitinase sequences. Southern blot analysis suggested that a single copy of the gene exists in the genome of T. roseum. The deduced open reading frame of 1,143 nucleotides encodes a protein of 380 amino acids with a calculated molecular wei

Abstract:

ABSTRACT Trichoderma virens is a mycoparasitic fungus used in biocontrol of soilborne plant pathogens. It inhibits or kills plant-pathogenic fungi through production of antifungal antibiotics and parasitism of hyphae and sclerotia. Conidiation, or the production of asexual spores, an inducible process triggered by light or nutrient stress, is an important trait in survival and also development of formulation products. In many fungi, signaling pathways, including mitogen-activated protein kinase (MAPK) cascades, have been implicated in parasitism of host plants as well as in the production of a

Abstract:

Bananas are important crops in developing countries with tropical climate. In Mexico, the banana production has increased, and it must be guaranteed. The Panama disease, caused by the fungus Fusarium oxysporum f.sp. cubense threatens the current banana production, for what is necessary to implement methods to protect this crop. Fungi from genus Trichoderma are natural residents of the rhizosphere. This genus comprises mycoparasite species used to control diseases caused by phytopathogenic fungi, and also benefit plant development. In this report, we present data of the identification and chara

Abstract This work was focused on the characterization of novel isolate of Trichoderma atroviride O1, found in the forest around the village of Zázrivá (the Northern Slovakia, region Orava). The isolate was identified by sequencing its internal transcribed spacer (ITS) region of rDNA. T. atroviride O1 stimulated the development of lateral roots of model plant Lepidium sativum. Simultaneously, the isolate has proved its high mycoparasitic potential as it displayed the ability to attack colonies of phytopathogenic fungi (Alternaria alternata, Fusarium culmorum, Botrytis cinerea).

Abstract:

SynopsisPteridophytes with subterranean sexual stages exist in five families. Their prothalli grow underground without light, nourished by fungi, and are rounded, massive, and without chlorophyll. Various authors have suggested that such gametophytes may inhibit outbreeding ability and that minor variations may therefore form in colonies through inbreeding.This paper questions these ideas. The subterranean condition is believed to be suited to fields, grassy meadows, and other habitats subject to seasonal drying. The parenchymatous thallus makes possible water storage.

Trichoderma harzianum is a well-known mycoparasitic fungus that has been used as biocontrol agent of many phytopathogenic fungi. One of the effort to improve the ability of wild strain of T. harzianum in its antagonistic activity is by exposed them in gamma ray iradiation. In this experiment wild strain of T. harzianum iradiated gamma ray of Cobalt-60 (0.25 kGy, 0.5 kGy, 0.75 kGy, and 1 kGy), then assess the effect of the iradiation on its growth, the antagonistic activity and chitinase activity toward Fusarium oxysporum. Results showed that iradiation of gamma ray 0.25–1 kGy has no effect on

Abstract:

Tremellomycetes rDNA sequences previously detected in wheat kernels by MiSeq were not reliably assigned to a genus or clade. From comparisons of ribosomal internal transcribed spacer region (ITS) and subsequent phylogenetic analyses, the following three basidiomycetous yeasts were resolved and identified: Vishniacozymavictoriae, V. tephrensis, and an undescribed Vishniacozyma rDNA variant. The Vishniacozyma variant’s clade is evolutionarily close to, but phylogenetically distinct from, the V. carnescens clade. These three yeasts were discovered in wheat kernel samples from the Canadian prairie
