Transbilayer phosphatidylethanolamine (PtdEtn) movements in the plasma membrane of Saccharomyces cerevisiae are regulated by an ATP-dependent, protein-mediated process(es). To examine whether this process is influenced by the actin cytoskeleton, we have studied the PtdEtn translocation in S. cerevisiae cells after treatment with microfilament disrupting and microtubule-disrupting agents. PtdEtn...

Two bioassay methods were modified to evaluate persistence, adsorption and biological availability of the fungicide benomyl in soil. The amount of biologically-available fungicide was assayed using the fungus Penicillium expansum Link ex Gray. The bioassay results were not significantly different from those obtained by spectrophotometry. The bioassays detected methyl 2-benzimidazole carbamate (...

Monilinia laxa is a pathogen of brown rot of stone fruit and almond in California, causing blossom blights and fruit rots. In this study, low-level resistance to the benzimidazole fungicides benomyl and thiophanate-methyl was detected in field isolates of M laxa collected from stone fruits and almonds in California. Low-resistant (LR) isolates grew in potato dextrose agar (PDA) plates amended w...

Some members of the familyClavicipitaceae are endophytic and have mutualistic relationship with the plant family Poaceae. Their relationship is beneficial for both host and fungus. In the present investigation, endophytic fungi were isolated from seed and leaf sheath of hosts Festuca arundinacea, F. ovina, F. pratensis, Bromus tomentellus, Melica persica and Lolium prenne. Morphological charact...

Fungi of the genusAspergillus werea continuing problem on the newly developed eldana diet in multicell trays. Various control attempts are outlined. They include hygiene practises, adjustment of dietary pH, and incorporation of the fungicides benomyl, mancozeb, captab, methyl paraben and sodium propionate into the diet. Treatment of the corn cob grits used for larval inoculation was also invest...
