Morphological changes in pathogenic fungi often underlie the development of virulence and infection by these organisms. Our knowledge of the components of the cell signalling pathways controlling morphological switching has, to a large extent, come from studies of pseudohyphal growth of the model organism Saccharomyces cerevisiae, in which control is exerted via changes in the intracellular cAM...

The effect of essential oils thyme, peppermint, savory and two fungicides on the growth three plant pathogenic fungi

Prevalent fungal pathogens of cereals in Lithuania belong to diverse systematic groups and this makes search for microbial biocontrol measures rather difficult. One of the options would be broad-spectrum biocontrol agents. In order to find these, 1037 seed-borne and 11 soil-borne rhizosphere pathogenic fungi were isolated and their systematic position determined. Fungi of genera Alternaria, Ulo...

Fungi associated with seeds of five cultivars of rice were isolated by agar and blotter paper methods. The fungus was isolated from the contaminated surface of unmilled rice grain and identified based on their typical structure and basic characters as suggested by Barnett and Hunter (1972). Five pathogenic fungi, namely Aspergillus flavus, A. niger, Penicillium citrinum, Alternaria padwickii an...

The nucleotide sequences of the D1/D2 domains of large subunit (26S) ribosomal DNA for 76 strains of 46 species of pathogenic dematiaceous fungi and related taxa were determined. Intra-species sequence diversity of medically important dematiaceous fungi including Phialophora verrucosa, Fonsecaea pedrosoi, Fonsecaea compacta, Cladophialophora carrionii, Cladophialophora bantiana, Exophiala derma...

Five soil-transmitted pathogenic fungi (Aspergillus niger) were isolated and selected to investigate the effect of Rare earth elements on their disease causing ability. The present study reveals the response of leguminous plant (Arachis hypogaea L.) to monazite soil containing Rare earth elements. A significant increase in plant biomass, total chlorophyll content and stress resistant product (p...

garlic and onion are very important crops which are cultivated especially in autumn season in jiroft region, southeast of iran. one of the limiting factors for development of cultivation of these crops is fungal diseases such as leaf spot and blight. for identifying the causal agents of this disease, numerous onion and garlic fields were surveyed during 2001-2003 and infected samples were colle...
