The sphinganine-analog mycotoxins (SAMs) fumonisin B1 and AAL toxins are inhibitors of eukaryotic sphinganine N-acyltransferase in vitro. Treatment of eukaryotes with SAMs generally results in an accumulation of sphingoid base precursors and a depletion of complex sphingolipids. The asc,asc genotypes of tomato (Lycopersicon esculentum) and Nicotiana umbratica are sensitive to SAMs and host of t...

The host-selective AAL toxins secreted by Alternaria alternata f sp lycopersici are primary chemical determinants in the Alternaria stem canker disease of tomato. The AAL toxins are members of a new class of sphinganine analog mycotoxins that cause cell death in both animals and plants. Here, we report detection of stereotypic hallmarks of apoptosis during cell death induced by these toxins in ...

Crop management systems influence plant productivity and nutrient use efficiency, as well as plant growth-promoting rhizobacteria (PGPR), which are known to influence the growth of plants via phytohormone production, phosphate solubilization, nitrogen (N) fixation and antimicrobial activity. The objective of this study was to compare the influence of two crop management system on microbial PGPR...

in this study, 42 samples of silage were collected in qaemshahr city in iran during fall 2011. samples were tested by competitive elisa for total aflatoxins. seven samples (16.7%) (mean±se:1.24) from 42 silage samples were positive with total aflatoxin (1.1-27.3 ppb) in nov., dec. and oct. the highest contamination was observed in oct., three samples (21.4%) from 14 samples were contaminated wi...

BACKGROUND Onychomycosis are caused by dermatophytes and Candida, but rarely by non- dermatophyte molds. These opportunistic agents are filamentous fungi found as soil and plant pathogens. OBJECTIVES To determine the frequency of opportunistic molds in onychomycosis. METHODS A retrospective analysis of 4,220 cases with onychomycosis, diagnosed in a 39-month period at the Institute of Dermat...

The principles of good agricultural and horticultural practice, considering both environmental protection high yielding plants, require modern cultivation methods. In agriculture, it is possible to use biostimulants that protect the soil against degradation plants phytopathogens stress. purpose 3-year field laboratory studies was determine effect Trichoderma harzianum T-22 other on health statu...

10 11 ABSTRACT 12 13 The aim of this research was to exploit natural products chemistry to control the incidence and extent 14 of mould growth in housing hence improving the sustainability of building products. 15 16 In this study, 7 extracts of the essential oils were screened in a nutrient medium for their antimould 17 activity against 3 common moulds, viz C. herbarum, Penicillium sp. and Alt...

The investigation was carried out at the laboratory of Plant Pathology Department, SASRD, Nagaland University (NU), Medziphema Campus, Nagaland, India during year kharif (August-October, 2020) to evaluate antagonistic potentiality Trichoderma spp. (T. harzianum, T. asperellum and virens) against three diseases pigeonpea viz. Alternaria leaf spot (Alternaria alternata), Collar rot (Sclerotium ro...

The community of endophytic fungi associated with Acer ginnala, a common tree in northeastern China, was investigated. Four media, PDA, Czapek's, WA and Sabouraud's, were used to inoculate explants from seeds, annual twigs and perennial twigs (xylem and bark). Media strongly affected the isolated species number, but not colonization frequency (CF) or isolation frequency (IF). To investigate med...
