Tuber melanosporum is a mycorrhizal ascomycetous fungus with subterranean fruiting bodies. With the aim of characterizing its state of maturity, we have undertaken a comparative analysis of the biochemical composition of tree stages. The various comp

Sporisorium reilianum f.sp. zeae, the causal agent of head smut, infects the roots of the maize plantlets. Little information is available concerning the development of the fungus in soil, although this saprophytic phase is an important part of the l

Sporisorium reilianum f.sp. zeae is the causal agent of maize head smut. Using microscopy, we describe the development of the fungus during its saprophytic and parasitic phase. When compatible, the yeast forms fused to produce dicaryotic hyphae. Thes

Sporisorium reilianum f. sp. zeae is the causal agent of head smut of maize. Although the main symptom of this disease is the formation of a black fungal sorus on the reproductive parts of the maize, the infection always occurs via the roots. Early i

A cytological study was carried out to describe the initial steps of infection of maize roots by the soil fungusSporisorium reilianum f. sp.zeae. Morphogenetic changes of the fungal cells were induced in the presence of maize roots. Extensive hyphal

Phylogenetic relationships among truffle species from Europe and China were investigated through parsimony analysis of the ITS sequences. Three major clades were obtained among the species analysed. The so-called white truffles appeared polyphyletic

Sporisorium reilianum f. sp. zeae is the causal agent of maize head smut, a disease present in several regions of France. A cytological study was carried out to describe a key step of the fungal etiology, in which the mycelium invades the vegetative

Membranes of young hyphae of Botrytis cinerea and Sclerotium rolfsii in the presence or absence of monensin were isolated and their chemical content was determined. Monensin induced a reduction of protein/lipid and sterol/phospholipid ratios. These m

A glycoprotein of 34 kDa (GP 34) was solubilized at acidic pH from the mycelium of Phytophthora parasitica var. nicotianae and was purified by ion exchange and gel permeation chromatography. Whole tobacco plants treated with GP 34 through their roots

A new method for the purification of melanin extracted from Tuber melanosporum Vitt. with KOH under nitrogen was developed. The physical and chemical properties of the resulting dark pigment were determined, including its elemental composition and ul
