Chemical Characterization of the Degradation of Necromass from Four Ascomycete Fungi: Implications for Soil Organic Carbon Turnover and Storage
Terrestrial soils store approximately twice as much carbon as is currently in the atmospheric CO2 pool. Despite its importance in the global carbon cycle, much is still unknown about the source, turnover, and stability of the soil organic matter (SOM) pool. For example, fungi are known to play an …

Distribution Patterns and Taxonomy of Freshwater Ascomycetes Along the Florida Peninsula
… and beta diversity reveal that the freshwater ascomycete community composition differs along the temperate-subtropical ecotone of the Florida peninsula. Ordination analysis shows that pH might also be an important factor in the distribution patterns of freshwater ascomycetes in Florida. Results …

Diversity of yeasts associated with wood and the gut of wood-feeding insects
… 6). This study confirmed the routine presence of ascomycete yeasts from the clades Scheffersomyces, Spathaspora, Lodderomyces, and Sugiyamaella in the guts of wood roaches and passalid beetles, as well as basidiomycete yeasts in the genera Cryptococcus and Trichosporon in passalids exclusively. In …

Investigations of lipid metabolism in Yarrowia lipolytica
… was conducted. Yarrowia is an oleaginous ascomycete that is capable of growing on many different substrates, which derives its name from its high efficiency of growth on lipids. Once the exogenous lipids are converted into free fatty acids and internalized by the yeast, the primary mode of …

GEOTRICHUM GALACTOMYCETUM: INTRASPECIFIC PHYSIOLOGICAL DIVERSITY AND BIOTECHNOLOGICAL POTENTIAL OF SIX STRAINS ISOLATED FROM POULTRY MANURE
Geotrichum galactomycetum is an ascomycete fungus species with high levels of divergency and has seen a recent change in its classification. In this paper, I will discuss the morphological and physiological distinctions seen in six Ge. galactomycetum strains (13-01 to 13-06) for the first time. The …

Mutational and functional analyses of the dynein heavy chain indicate the existence of an apical-sistal transport cycle in cells
… of dynein. The study presented here utilized the ascomycete fungus Neurospora crassa in a series of genetic, cell biological and complementing biochemical approaches to study dynein function and regulation. The study is divided into two sections of which the first section will focus on the effects …

A Genomic and Proteomic Investigation of the Plant Pathogen Armillaria mellea: Buried Treasure or Hidden Threat?
… proteome, reminiscent of both basidiomycete and ascomycete glycodegradative arsenals. Under oxidative stress, A. mellea underwent extensive proteome remodelling within 3 hours and comparative proteomics detected differentially regulated proteins (n = 14). Expression of proteins involved in …

Genes and mechanisms in Arabidopsis innate immunity against Leptosphaeria maculans
Leptosphaeria maculans is a hemibiotrophic ascomycete that causes blackleg disease on Brassica oilcrops, which globally is a great threat for oilseed production. In order to obtain mechanistic understanding of this devastating pathogen, Arabidopsis thaliana was used as a model host. Susceptible …

Characterization of Pyrenophora Tritici-Repentis in Wheat and Rye to Study Tan Spot Susceptibility and Insights Into Its Relationship with Stem Rust Resistance
<p>Tan spot, caused by the ascomycete fungus, Pyrenophora tritici-repentis (Ptr), is a major foliar fungal disease of wheat worldwide. To date, Ptr isolates have been grouped into eight races based on the production of three host selective effectors (toxins), Ptr ToxA, ToxB, and ToxC, which are …

Reprogramming the expression of the double-stranded RNA mitovirus OnuMV1c from the mitochondria to the cytoplasm in the fungal pathogen Ophiostoma novo-ulmi
… pandemic of this disease is caused by the ascomycete fungal pathogen Ophiostoma novo-ulmi. A number of strategies have been used to attempt to mitigate the effects of DED but none have met any sustainable success, and the disease continues to have severe ecological and economic impacts. …

Dissection of black rot resistance towards marker-assisted breeding in grapevine Pedigree reconstruction and phenotyping optimization coupled with high-density linkage mapping revealed a major QTL associated with bunch resistance.
… rot (BR) is a destructive disease caused by the ascomycete, Phyllosticta ampeli-cida, whose telomorphic form was known as Guignardia bidwellii. In the European continental area in the last two decades its pressure increased due to the concomitant decreased usage of chemicals and the occurrence of …

Epidemiological studies on primary inoculum of Venturia inaequalis and V. asperata for apple scab management
Apple scab, caused by the ascomycete Venturia inaequalis, is the most important disease of apple, causing great losses worldwide. Its management is largely based on fungicide treatments, especially targeting ascosporic infections. To reduce the pesticide input, sanitation practices against …

Identification of up-regulated genes of the hyphomycete, Beauveria bassiana, during infection of Leptinotarsa decemlineata
… which shares homology with an unknown ORF of the ascomycete N. crassa. Grown in the presence of its host cuticle, B. bassiana seemed to over-expressed several hydrolases probably involved in the degradation of the cuticle. B. bassiana seemed to up-regulate also the expression of genes involved in …

Spread of White Hypovirulent Strains of Cryphonectria Parasitica Among American Chestnut Trees at the Lesesne State Forest
Sixty-two natural cankers on branches and main stems of three 16-year-old grafted American chestnut trees at the Lesesne State Forest were sampled for Cryphonectria parasitica. Cankers were sampled in 1996 and 1997 at various distances from the main stem zone on the grafts (ground to 183 cm) that …

Respuestas fúngicas a señales ambientales: Funciones de las proteínas CarO, OpsA, CutA y AcyA en Fusarium fujikuroi
The ascomycete fungus Fusarium fujikuroi (Gibberella fujikuroi MP-C) produces secondary metabolites of biotechnological interest, such as gibberellins, bikaverin, and carotenoids. Production of these metabolites is regulated by nitrogen availability and, in a specific manner, by other environmental …
