Mushrooms are very appreciated as food in several countries and, besides their fine taste, they have great nutritional value as sources of essential fatty acids, minerals, proteins and biologically active metabolites. By the other hand, nonbasidiomycete filamentous fungi from several genera such as Rhizopus or Penicillium are commonly not associated with human diet. Nevertheless, these and othe...
Mucorales are a group of basal fungi that includes the casual agents of the human emerging disease mucormycosis. Recent studies revealed that these pathogens activate an RNAi-based pathway to rapidly generate drug-resistant epimutant strains when exposed to stressful compounds such as the antifungal drug FK506. To elucidate the molecular mechanism of this epimutation pathway, we performed a gen...
The cAMP signal transduction pathway controls many processes in fungi. The Mucor circinelloides pkaR and pkaC genes, encoding the regulatory (PKAR) and catalytic (PKAC) subunit of the cAMP-dependent protein kinase A (PKA), have been cloned recently. Expression analysis during the dimorphic shift and colony morphology suggested a role for PKAR in the control of morphology and branching. Here str...
The protein kinase A (PKA) signaling pathway plays a role in regulating growth and differentiation in the dimorphic fungus Mucor circinelloides. PKA holoenzyme is comprised of two catalytic (C) and two regulatory (R) subunits. In M. circinelloides, four genes encode the PKAR1, PKAR2, PKAR3, and PKAR4 isoforms of R subunits. We have constructed null mutants and demonstrate that each isoform has ...
بیوسورفکتانتها ترکیبات فعال سطحی هستند که توسط بسیاری از میکروارگانیسمها تولید میشوند. این ترکیبات دارای کاربردهای بسیاری در صنایع گوناگون به ویژه در صنعت نفت و پاک سازی آلودگیهای نفتی هستند. در این پژوهش از میان 22 جدایهی مخمر جداسازی شده از 8 نمونه خاک آلوده به هیدروکربنهای نفتی در نهایت جدایهی G-13 با قطر هالهی 1/13 سانتی متر و کاهش کشش سطحی به میزان 26 میلی نیوتون بر متر به عنو...
Plants and fungi use light and other signals to regulate development, growth, and metabolism. The fruiting bodies of the fungus Phycomyces blakesleeanus are single cells that react to environmental cues, including light, but the mechanisms are largely unknown [1]. The related fungus Mucor circinelloides is an opportunistic human pathogen that changes its mode of growth upon receipt of signals f...
The cyclic AMP (cAMP)-dependent protein kinase A (PKA) signaling pathway plays a role in regulating development, growth, and virulence in a number of fungi. To determine whether PKA plays a similar function in zygomycete fungi, a mutant of Mucor circinelloides was generated that lacks pkaR1, one of the regulatory subunits of PKA. The mutant showed a reduction in growth and alterations in germin...
