In this study, we analyzed the different parts of mushrooms using electron spin resonance (ESR) to identify radical species, and examined their hydroxyl scavenging activities. The four kinds investigated in Agrocybe cylindracea (Shakkiko1 Shakkiko2), Grifola gargal, Coprinus comatus were separated into caps, stipes, bases stipes. ESR spectra all specimens consisted signals originating from orga...

The B mating type locus of the basidiomycete Coprinus cinereus encodes a large family of lipopeptide pheromones and their seven transmembrane domain receptors. Here we show that the B42 locus, like the previously described B6 locus, derives its unique specificity from nine multiallelic genes that are organized into three subgroups each comprising a receptor and two pheromone genes. We show that...

Substances which are effective in inducing fruiting bodies in monokaryotic mycelia of the fis(+) strain of Coprinus macrorhizus were purified and characterized. The active components of fruiting-inducing substances were identified as adenosine-3'-monophosphate, adenosine 3',5'-cyclic monophosphate (cyclic AMP), and a protein which is bound with the cyclic AMP. Cyclic AMP was synthesized from ad...

Handsome fungus beetle Lycoperdina succincta (Linnaeus, 1767) from the family Endomychidae is first recorded Kazakhstan (North Kazakhstan, Akmola, and North regions South-East Almaty region). The finds of L. region are currently southernmost localities for this species a new record Central Asia. Coprinus comatus (O.F. Müller) Persoon, 1797, Tulostoma volvulatum I.G. Borshchov, 1865, Bo...

Inspection of the genome of the ligninolytic basidiomycete Phanerochaete chrysosporium revealed an unusual peroxidase_like sequence. The corresponding full length cDNA was sequenced and an archetypal secretion signal predicted. The deduced mature protein (NoP, novel peroxidase) contains 295 aa residues and is therefore considerably shorter than other Class II (fungal) peroxidases, such as ligni...

Removal of large segments of the apical part of the stipe of Coprinus cinereus (extending to about half its length) affected neither the ability of the stipe to show gravitropic bending nor its ability to compensate the curvature so induced and adjust to the vertical. However, gravitropic reaction time was directly proportional to the amount of stipe removed. Application of lateral loads of up ...

The time-course study of meiosis in the fungus Coprinus cinereus (C. lagopus) by electron microscopy reveals that two monoglobular spindle pole bodies (SPB's) of prekaryogamy nuclei come together during karyogamy and are fused. The fusion SPB of postkaryogamy nucleus persists through zygotene and pachytene as evidenced by the presence of axial components and synaptonemal complexes. At early dip...
