Selection and Amplification of Fungicide Resistance in in Relation to DMI Fungicide Use in Agronomic Settings: Hotspots versus Coldspots.

is a ubiquitous saprophytic fungus. Inhalation of spores can lead to Invasive Aspergillosis (IA) in people with weakened immune systems. The use of triazole antifungals with the demethylation inhibitor (DMI) mode of action to treat IA is being hampered by the spread of DMI-resistant "ARAf" (azole-resistant ) genotypes.

Fusarium in wheat: importance and toxin production in the field - possibilities and limits of fungicide treatments.

Effects of plant cropping measures on toxin production were investigated. The use of the plough reduced the DON level by 71%. Additionally, the choice of less sensitive varieties, as well as an adequate nitrogen fertilization showed a significant reduction of the DON content in grain.

Lachnellins A, B, C, D, and naphthalene-1,3,8-triol, biologically active compounds from a Lachnellula species (ascomycetes).

In the course of our search for new biologically active metabolites, lachnellin A (1), a metabolite with high cytotoxic and antimicrobial activities, the structurally related lachnellins B, C and D (3, 4, 7), and naphthalene-1,3,8-triol (8), an inhibitor of malate synthase (EC 4.1.3.

Tyromycin A: a novel inhibitor of leucine and cysteine aminopeptidases from Tyromyces lacteus.

Tyromycin A, a new inhibitor of leucine and cysteine aminopeptidases has been isolated from mycelial cultures of the basidiomycete Tyromyces lacteus (Fr.) Murr. Its structure was established as 1,16-bis-[4-methyl-2,5-dioxo-3-furyl]hexadecane (1) by spectral analysis and transformation into ester and imide derivatives.

Ultrastructural differentiation of glandular stomach (proventriculus) in chick embryo.

Cytochemical characterization of mucosubstances of chick glanular stomach (proventriculus) changes from 15 days of development to postnatal and adult stages was studied. To corroborate these data cytochemical, ultrastructural and ultracytochemical study of chick embryo proventriculus from 7 to 20 days of development was performed. At the 7th day several layers of undifferentiated cells formed an epithelium which covered the walls of the glandular stomach.
