Pheromone signaling plays an essential role in the mating and sexual development of mushroom fungi. Multiallelic genes encoding the peptide pheromones and their cognate 7-transmembrane helix (7-TM) receptors are sequestered in the B mating type locus. Here we describe the isolation of the B6 mating type locus of Coprinus cinereus. DNA sequencing and transformation analysis identified nine genes...

Secondary metabolites produced by Trichoderma viride, a deuteromycetes fungus, under submerged culture condition were formulated and evaluated for oviposition attractancy against gravid females of Culex quinquefasciatus mosquito. At a concentration of 10 g ml-1 the formulation showed remarkable attractancy with an oviposition active index (OAI) of +0.52. When the oviposition attractancy of the...

This study was carried out to continue identifying unknown and less known anamorphic fungi from Guilan province. Plant materials with fungal signs and symptoms were collected and examined to identify causal agents. Four species viz. Alternariacalendulae (on Calendulaofficinalis), Pseudocercosporasordida(on Campsis sp.), Thedgonia ligustrina (on Ligustrum vulgare) and Zygosporium oscheoides (on ...

Mortality of German cockroaches, Blattella germanica (L.), caused by Metarhizium anisopliae (Metschnikoff) Sorokin strain AC-1 alone and in combination with different formulations of boric acid, was evaluated in laboratory bioassays. Topical application of M. anisopliae alone (8.96 10 conidia/m) required 28 days to cause >92% cockroach mortality (LT50 10 days). In contrast, in combination with ...

Though light induced reproduction, both sexual an(l asexual, is common to many fungi (15), the mlechanisnm ;of this phenomenon is not un(lerstood. Suggestions have been made on the possible nature of a photoreceptor pigment involved (5) but there has been little experimental evidence to support or refute these views. Recent studies with .4scochyta pisi, Lib. (9), Pleospora herbarunm (Pers.) Rab...

Penicillium griseoroseum, a deuteromycete fungus producer of pectinolytic enzymes, was transformed with a gene encoding for green fluorescent protein (GFP). The selection of transformants was based on the homologous nitrate reductase gene (niaD). Protoplasts of a P. griseoroseum Nia mutant (PG63) were co-transformed with the plasmids pNPG1 and pAN52-1-GFP. The plasmid pNPG-1 carries the homolog...

A fusidane triterpene, 16-deacetoxy-7-beta-hydroxy-fusidic acid (1), was isolated from a fermentation of the mitosporic fungus Acremonium crotocinigenum. Full unambiguous assignment of all (1)H and (13)C data of 1 was carried out by extensive one- and two-dimensional NMR studies employing HMQC and HMBC spectra. Compound 1 was tested against a panel of multidrug-resistant (MDR) and methicillin-r...

An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite Meloidogyne arenaria. The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (Gigaspora albida, Claroideoglomus etunicatum, Acaulospora longula, and a non-inoculated control) in the ...

sooty molds are a group of fungi with dark-coloured hyphae, which grow saprophytically on various living plant organs and sometimes on non-living substrates and produce brown to black superficial colonies, black pellicles or pseudoparenchymatous crust. in north of iran including guilan and mazandaran provinces, sooty molds are common on living leaves of a great variety of plants especially citr...
