Abstract:

A new isoquinoline alkaloid, ampullosine (3-methyl-isoquinoline-6-carboxylic acid, 1), was isolated from Sepedonium ampullosporum and characterized by spectroscopic analysis and chemical reactions. This compound is responsible for the deep yellow color of the culture fluid of this species. Moreover, the known compounds sepedonin (2) and anhydrosepedonin (3) were detected. Twelve strains belonging to eight species of Sepedonium have been screened for these three metabolites by LC/ESI-SRM (selected reaction monitoring). Ampullosine (1) could be detected in almost all species in Sepedonium, but n

Abstract:

Four new 19-residue peptaibols, named tulasporins A–D (1–4), were isolated from the semi-solid cultures of Sepedonium tulasneanum. Their structures were elucidated on the basis of extensive ESI-HRMSn fragmentation studies as well as 1H NMR spectroscopic analyses. Interestingly, the structures of tulasporins A–D (1–4) resemble those of chrysospermins isolated earlier from cultures of S. chrysospermum. Previously, it was hypothesized that the peptaibol production by Sepedonium species correlates with the morphology of the aleurioconidia, as exclusively round-shaped aleurioconidia forming species

Abstract:

We present the first major survey of regional diversity, distribution and host-association of Sepedonium. Whereas the rather scarce worldwide records of this mycoparasitic fungus suggested no specific distribution pattern of most species before, we provide new evidence of endemic and specific host-parasite guilds of Sepedonium in Southern South America, including the description of a new species. The corresponding inventory was performed in temperate central Chile. The regional landscape, a mosaic of exotic timber plantations and remnants of native Nothofagus forests, facilitates a unique comb

Abstract:

During an investigation of fungicolous fungi associated with mushrooms in China, four boleticolous fungi were collected from Sichuan Province. Based on the morphological features and multi-gene phylogenetic analyses this study introduces two new species, Hypomyces ampullaris, and H. sichuanensis. The new species are described and illustrated comprehensively and compared with their related fungi. Hypomyces ampullaris is similar to Sepedonium ampullosporum in forming candelabrum-like conidiophores and producing ampulliform conidia but differs from the latter in having shorter phialides and small

The lamellate boletes found in the Cooloola Sand-mass, Queensland are described and discussed in the light of earlier Australian records of paxilloid fungi. Nine species of Paxillus are discussed, two in Tapinella, which is maintained as a separate entity, and 11 are assigned to Phylloporus. Of the last, eight are new records to Australia and two are new species. Three appendices cover various aspects of studies on Australian boletes which have come to light since the publication of this series, including notes on the host-range of the parasitic hyphomycete Sepedonium.

One gene of this family in C. michiganensis subsp. sepedonicus, chp-7, is required for triggering HR in Nicotiana tabacum.

Abstract:

It has been previously shown that the chemically synthesized nanocomposite of selenium with arabinogalactan (NC Se/AG) is characterized by antibacterial effect upon the agent of ring rot – gram-positive bacterium Clavibacter sepedonicus (Cms), with the NC Se/AG having no negative effect on potato plants. In the present paper, it has been found that, 1 hour after the treatment of the NC Se/AG, a substantial elevation of lipid peroxidation products was observed in potato root tissues. This supports earlier results on the increase in reactive oxygen species (ROS) production in potato root tissues

Abstract Purpose The growth behavior of novel fungal isolates along with the production of bioactive compounds from mycelia mass during submerged fermentations were investigated using conventional synthetic media and agro-industrial residues as fermentation substrates. Methods Four novel isolated fungi, belonging to edible or medicinal species, were evaluated for their ex-situ growth on potato dextrose agar. Specific attention was designated to Sepedonium sp. and Phellinus sp. considering their high growth rate in solid state fermentations. Submerged fermentations were subsequently employed us

Recent studies have indicated that the taxonomic rank of the subspecies must be re-evaluated. In this research, we assessed the taxonomic position of the three C. michiganensis subspecies and clarif

Abstract:

Potato (Solanum tuberosum) is a valuable cultivated vegetable with high nutritional qualities containing a variety of essential ingredients such as starch, vitamins and essential minerals. However cultivating potatoes is significantly complicated by diseases caused by a number of phytopathogens of both bacterial and fungal nature. Phytophthora infestans, Alternaria sp., Phoma exigua, Rhizoctonia solani, Fusarium sp., Verticillium sp., Clavibacter michiganensis subsp. sepedonicus, Pectobacterium sp., Dickeya sp. are considered amongst the most dangerous phytopathogens.

Abstract:

ABSTRACT Members of the genus Clavibacter are economically important bacterial plant pathogens infecting a set of diverse agricultural crops (e.g., alfalfa, corn, potato, tomato, and wheat). Tomato-associated Clavibacter sp. strains account for a great portion of the genetic diversity of the genus, and C. michiganensis sensu stricto (formerly C. michiganensis subsp. michiganensis), causing bacterial canker disease, is considered one of the most destructive seed-borne agents for the crop worldwide. However, current taxonomic descriptions of the genus do not reflect the existing diversity of the
