THE COMPARATIVE CHARACTERISTIC OF GENERAL CAROTENOID CONTENT IN SOME SPECIES OF BASIDIOMYCETES

There were investigated the total carotenoid content in fruiting bodies of 50 species of Basidiomycetes, 27 of which are belonging to order Polyporales and 23 to order Agaricales. The highest total carotenoid content in Ganoderma applanatum, Fistulina hepatica and Laetiporus sulfureus сarpophorus was found out. The dynamics of growth and accumulation of carotenoids in the mycelium and cultural filtrate of 24 strains of 8 basidiomycetes species were studied. Promising for the further research to develop the methods for carotenoids mycelial and extracellular origin strains of species Fistulina hepatica and Laetiporus sulphureus were selected.

Xylophilous Agaricomycetes (Basidiomycota) of the Brazilian Cerrado

An updated checklist of xylophilous Agaricomycetes from the Brazilian Cerrado showed 127 species, 22 families and nine orders (Agaricales, Atheliales, Auriculariales, Corticiales, Gloeophyllales, Hymenochaetales, Polyporales, Russulales, and Thelephorales). The new list includes new specimens collected between 2009 and 2011 in Reserva Biológica de Mogi-Guaçu, São Paulo State, Brazil, and a revision of material previously known from Cerrado. Twelve species are mentioned for the first time for Brazil and 51 are recorded as new for the Cerrado.

Fatty acid composition of wild mushroom species of order Agaricales—Examination by gas chromatography–mass spectrometry and chemometrics

Applying gas chromatography–mass spectrometry of 4,4-dimethyloxazoline fatty acid derivatives, the fatty acid composition of 15 mushroom species belonging to 9 genera and 5 families of order Agaricales growing in Bulgaria is determined. The structure of 31 fatty acids (not all present in each species) is unambiguously elucidated, with linoleic, oleic and palmitic acids being the main components (ranging between 70.9% (Marasmius oreades) and 91.2% (Endoptychum agaricoides)). A group of three hexadecenoic positionally isomeric fatty acids, 6-, 9- and 11–16:1, appeared to be characteristic components of the examined species. By applying chemometrics it was possible to show that the fatty acid composition closely reflects the classification of the species.

Phylogenetically diverse endozoic fungi in the South China Sea sponges and their potential in synthesizing bioactive natural products suggested by PKS gene and cytotoxic activity analysis

Sponges are well documented to harbor large amounts of microbes. Though it is known that sponge-derived fungi are important sources for marine natural products, the phylogenetic diversity and biological function of sponge-associated fungi remain largely unknown. In this study, the diversity of culturable endozoic fungi in sponges from the South China Sea was revealed based on the ITS phylogenetic analysis. Meanwhile the fungal potential for producing bioactive natural products was estimated according to the detection of Beta-ketosynthase in the polyketide synthase (PKS) gene cluster and cytotoxic activity bioassay. As a result, diverse fungi including 14 genera (Aspergillus, Penicillium, Scolecobasidium, Eurotium, Alternaria, Fusarium, Hypocreales, Yarrowia, Candida, Hypoxylon, Sporidiobolus, Schizophyllum, Bjerkandera, and Trichosporon) in ten orders (Xylariales, Moniliales, Pleosporales, Saccharomycetales, Hypocreales, Eurotiales, Sporidiobolales, Agaricales, Aphyllophorales and Tremellales) of phyla Ascomycota and Basidiomycota were isolated with Aspergillus as the predominant component in the culturable fungal community. Particularly, genera Schizophyllum, Sporidiobolus, and Bjerkandera in phylum Basidiomycota and genus Yarrowia in phylum Ascomycota were isolated from marine sponges for the first time. PKS genes were detected in 12 isolates suggesting their potential for synthesizing PKS compounds. Among the 12 isolates with PKS genes, 9 isolates displayed strong in vitro cytotoxic activity (e.g. IC50 < 50 μg/ml) against human cancer cell lines A-549, Bel-7402, A-375 and MRC-5. This study demonstrates the phylogenetically diverse endozoic fungi in South China Sea sponges, and highlights the potential of sponge-associated fungi in producing biologically active natural products.

Pigments of higher fungi - a review

This review surveys the literature dealing with the structure of pigments produced by fungi of the phylum Basidiomycota and also covers their significant colourless precursors that are arranged according to their biochemical origin to the shikimate, polyketide and terpenoid derived compounds. The main groups of pigments and their leucoforms include simple benzoquinones, terphenylquinones, pulvinic acids, and derived products, anthraquinones, terpenoid quinones, benzotropolones, compounds of fatty acid origin and nitrogen-containing pigments (betalains and other alkaloids). Out of three orders proposed, the concern is only focused on the orders Agaricales and Boletales and the taxonomic groups (incertae sedis) Cantharellales, Hymenochaetales, Polyporales, Russulales, and Telephorales that cover most of the so called higher fungi often referred to as mushrooms. Included are only the European species that have generated scientific interest due to their attractive colours, taxonomic importance and distinct biological activity. &amp;nbsp;

Additions to the knowledge of aphyllophoroid fungi (&lt;I&gt;Basidiomycota&lt;/I&gt;) of Atlantic Rain Forest in São Paulo State, Brazil

The list of aphyllophoroid fungi of the Atlantic Rain Forest in the state of Sao Paulo is updated. Specimens were collected in four different areas of the Atlantic Rain Forest from 1988 to 2007. Exsiccates deposited in the Herbarium SP were also studied. A list of 85 species of Basidiomycota distributed into 11 families and four orders (Agaricales, Hymenochaetales, Polyporales, Russulales) is presented. All species are mentioned for the first time for the collection sites. Two species are reported for the first time for Brazil and 17 species are recorded for the first time for Sao Paulo State.

Antimicrobial Activity of Submerged Cultures of Chilean Basidiomycetes

This study is part of a screening program aimed at searching for bioactive metabolites from Chilean basidiomycetes. Submerged cultivation of fungal mycelia in liquid media was evaluated for antimicrobial activity. A total of 148 strains were obtained in vitro. The extracts produced from submerged cultures were evaluated against bacteria and fungi. In the primary antimicrobial assay, approximately 60% of the extracts presented positive biological activity. The highest frequencies of active strains were from the orders Agaricales (31.0%), Polyporales (20.6%), Sterales (18.3%), Boletales (11.4%), and Cortinariales (9.1%). Antifungal activity was more pronounced than antibacterial activity. Twelve extracts that exhibited strong antimicrobial activity showed minimum inhibitory concentration (MIC) values of 50 µL/mL against Bacillus brevis and 25∼50 µL/mL against Penicillium notatum and Paecilomyces variotii. The biological activity of some strains did not vary considerably, regardless of the substrate or collection site whereas, for others, it showed marked variations. Differences in antimicrobial activities observed in the different fungal genera suggested that the ability to produce bioactive compounds is not homogenously distributed among basidiomycetes. The information obtained from this study reveals that Chilean basidiomycetes are able to generate small and/or large variations in the normal pathway of compounds production. Thus, it is necessary to evaluate this biological and chemical wealth, which could be an unsuspected reservoir of new and potentially useful molecules.

Ectomycorrhizal lifestyle in fungi: global diversity, distribution, and evolution of phylogenetic lineages

The ectomycorrhizal (EcM) symbiosis involves a large number of plant and fungal taxa worldwide. During studies on EcM diversity, numerous misidentifications, and contradictory reports on EcM status have been published. This review aims to: (1) critically assess the current knowledge of the fungi involved in the EcM by integrating data from axenic synthesis trials, anatomical, molecular, and isotope studies; (2) group these taxa into monophyletic lineages based on molecular sequence data and published phylogenies; (3) investigate the trophic status of sister taxa to EcM lineages; (4) highlight other potentially EcM taxa that lack both information on EcM status and DNA sequence data; (5) recover the main distribution patterns of the EcM fungal lineages in the world. Based on critically examining original reports, EcM lifestyle is proven in 162 fungal genera that are supplemented by two genera based on isotopic evidence and 52 genera based on phylogenetic data. Additionally, 33 genera are highlighted as potentially EcM based on habitat, although their EcM records and DNA sequence data are lacking. Molecular phylogenetic and identification studies suggest that EcM symbiosis has arisen independently and persisted at least 66 times in fungi, in the Basidiomycota, Ascomycota, and Zygomycota. The orders Pezizales, Agaricales, Helotiales, Boletales, and Cantharellales include the largest number of EcM fungal lineages. Regular updates of the EcM lineages and genera therein can be found at the UNITE homepage http://unite.ut.ee/EcM_lineages . The vast majority of EcM fungi evolved from humus and wood saprotrophic ancestors without any obvious reversals. Herbarium records from 11 major biogeographic regions revealed three main patterns in distribution of EcM lineages: (1) Austral; (2) Panglobal; (3) Holarctic (with or without some reports from the Austral or tropical realms). The holarctic regions host the largest number of EcM lineages; none are restricted to a tropical distribution with Dipterocarpaceae and Caesalpiniaceae hosts. We caution that EcM-dominated habitats and hosts in South America, Southeast Asia, Africa, and Australia remain undersampled relative to the north temperate regions. In conclusion, EcM fungi are phylogenetically highly diverse, and molecular surveys particularly in tropical and south temperate habitats are likely to supplement to the present figures. Due to great risk of contamination, future reports on EcM status of previously unstudied taxa should integrate molecular identification tools with axenic synthesis experiments, detailed morphological descriptions, and/or stable isotope investigations. We believe that the introduced lineage concept facilitates design of biogeographical studies and improves our understanding about phylogenetic structure of EcM fungal communities.

A general suite of fungal endophytes dominate the roots of two dominant grasses in a semiarid grassland

Although research has shown that root associated fungi (RAF) are necessary for plant success in harsh environments, few studies have examined RAF community variability between different plant species coexisting in arid habitats. We compared the diversity and composition of the fungal communities colonizing dominant and important forage grasses, Bouteloua gracilis and Sporobolus cryptandrus, inhabiting the Sevilleta National Wildlife Refuge, a semiarid grassland in New Mexico. A third sympatric plant, Yucca glauca (Agavaceae), also was analyzed. ITS rDNA from roots, collected and amplified in 2007, yielded 447 fungal sequences. Sequences obtained from all three species suggest that grasses share a core group of RAF (90% of sequences representing the orders Pleosporales, Agaricales, and Sordariales). Conversely, 57% of the fungal community within Y. glauca was dominated by a different RAF cohort. The two most common OTUs within the grasses are related to Paraphaeospheria sp. and Moniliophthora sp. (91 and 85 of 331 sequences, respectively). These same two species accounted for 58% of isolates in culture-based analysis of the same grass root tissue. The presence of these RAF in several grass species, over several years, and at several sites suggests that grasses in semiarid landscapes share a similar cohort of fungal dominants.

Early development of Moniliophthora perniciosa basidiomata and developmentally regulated genes

BackgroundThe hemibiotrophic fungus Moniliophthora perniciosa is the causal agent of Witches' broom, a disease of Theobroma cacao. The pathogen life cycle ends with the production of basidiocarps in dead tissues of the infected host. This structure generates millions of basidiospores that reinfect young tissues of the same or other plants. A deeper understanding of the mechanisms underlying the sexual phase of this fungus may help develop chemical, biological or genetic strategies to control the disease.ResultsMycelium was morphologically analyzed prior to emergence of basidiomata by stereomicroscopy, light microscopy and scanning electron microscopy. The morphological changes in the mycelium before fructification show a pattern similar to other members of the order Agaricales. Changes and appearance of hyphae forming a surface layer by fusion were correlated with primordia emergence. The stages of hyphal nodules, aggregation, initial primordium and differentiated primordium were detected. The morphological analysis also allowed conclusions on morphogenetic aspects. To analyze the genes involved in basidiomata development, the expression of some selected EST genes from a non-normalized cDNA library, representative of the fruiting stage of M. perniciosa, was evaluated. A macroarray analysis was performed with 192 selected clones and hybridized with two distinct RNA pools extracted from mycelium in different phases of basidiomata formation. This analysis showed two groups of up and down-regulated genes in primordial phases of mycelia. Hydrophobin coding, glucose transporter, Rho-GEF, Rheb, extensin precursor and cytochrome p450 monooxygenase genes were grouped among the up-regulated. In the down-regulated group relevant genes clustered coding calmodulin, lanosterol 14 alpha demethylase and PIM1. In addition, 12 genes with more detailed expression profiles were analyzed by RT-qPCR. One aegerolysin gene had a peak of expression in mycelium with primordia and a second in basidiomata, confirming their distinctiveness. The number of transcripts of the gene for plerototolysin B increased in reddish-pink mycelium and indicated an activation of the initial basidiomata production even at this culturing stage. Expression of the glucose transporter gene increased in mycelium after the stress, coinciding with a decrease of adenylate cyclase gene transcription. This indicated that nutrient uptake can be an important signal to trigger fruiting in this fungus.ConclusionThe identification of genes with increased expression in this phase of the life cycle of M. perniciosa opens up new possibilities of controlling fungus spread as well as of genetic studies of biological processes that lead to basidiomycete fruiting. This is the first comparative morphologic study of the early development both in vivo and in vitro of M. perniciosa basidiomata and the first description of genes expressed at this stage of the fungal life cycle.

A re-evaluation of the lignocellulolytic &lt;I&gt;Agaricomycetes&lt;/I&gt; from the Brazilian semi-arid region

A checklist of the lignocellulolytic Agaricomycetes from the Brazilian semi-arid region is provided. It presents data on the distribution of 37 species, 10 families, and six orders (Agaricales, Auriculariales, Gloeophyllales, Hymenochaetales, Polyporales, and Russulales).

A literature-based checklist of the aphyllophoraceous fungi reported from the Brazilian Amazonia was compiled. Two hundred and sixteen species, 90 genera, 22 families, and 9 orders (Agaricales, Auriculariales, Cantharellales, Corticiales, Gloeophyllales, Hymenochaetales, Polyporales, Russulales and Trechisporales) have been reported from the area.

A genome survey of Moniliophthora perniciosa gives new insights into Witches' Broom Disease of cacao

BackgroundThe basidiomycete fungus Moniliophthora perniciosa is the causal agent of Witches' Broom Disease (WBD) in cacao (Theobroma cacao). It is a hemibiotrophic pathogen that colonizes the apoplast of cacao's meristematic tissues as a biotrophic pathogen, switching to a saprotrophic lifestyle during later stages of infection. M. perniciosa, together with the related species M. roreri, are pathogens of aerial parts of the plant, an uncommon characteristic in the order Agaricales. A genome survey (1.9× coverage) of M. perniciosa was analyzed to evaluate the overall gene content of this phytopathogen.ResultsGenes encoding proteins involved in retrotransposition, reactive oxygen species (ROS) resistance, drug efflux transport and cell wall degradation were identified. The great number of genes encoding cytochrome P450 monooxygenases (1.15% of gene models) indicates that M. perniciosa has a great potential for detoxification, production of toxins and hormones; which may confer a high adaptive ability to the fungus. We have also discovered new genes encoding putative secreted polypeptides rich in cysteine, as well as genes related to methylotrophy and plant hormone biosynthesis (gibberellin and auxin). Analysis of gene families indicated that M. perniciosa have similar amounts of carboxylesterases and repertoires of plant cell wall degrading enzymes as other hemibiotrophic fungi. In addition, an approach for normalization of gene family data using incomplete genome data was developed and applied in M. perniciosa genome survey.ConclusionThis genome survey gives an overview of the M. perniciosa genome, and reveals that a significant portion is involved in stress adaptation and plant necrosis, two necessary characteristics for a hemibiotrophic fungus to fulfill its infection cycle. Our analysis provides new evidence revealing potential adaptive traits that may play major roles in the mechanisms of pathogenicity in the M. perniciosa/cacao pathosystem.

Moniliophthora perniciosa, the causal agent of witches' broom disease of cacao: what's new from this old foe?

The first WDB symptoms appear to have been described in the diaries of Alexandre Rodrigues Ferreira (described as lagartão; meaning big lizard) from his observations of cacao trees in 1785 and 1787 in Amazonia, which is consistent with the generally accepted idea that M. perniciosa, like its main host T. cacao, evolved in this region. The disease subsequently arrived in Surinam in 1895. WBD moved rapidly, spreading to Guyana in 1906, Ecuador in 1918, Trinidad in 1928, Colombia in 1929 and Grenada in 1948. In each case, cacao production was catastrophically affected with yield reductions of 50-90%. After the arrival of M. perniciosa in Bahia in 1989, Brazil went from being the world's 3rd largest producer of cacao (347 000 tonnes in 1988-1990; c. 15% of the total world production at that time) to a net importer (141 000 tonnes in 1998-2000). Fortunately for chocolate lovers, other regions of the world such as West Africa and South East Asia have not yet been affected by this disease and have expanded production to meet growing world demand (predicted to reach 3 700 000 tonnes by 2010).

Molecular characterization of the basidiomycete isolate Nematoloma frowardii b19 and its manganese peroxidase places the fungus in the corticioid genus Phlebia

The basidiomycete isolate b19, originally identified by morphological characteristics of the fruiting body as Nematoloma frowardii, efficiently produces manganese peroxidase (MNP) and is used for degradation of natural, persistent aromatic polymers (lignin, humic acids and brown coal components). The N. frowardii MNP has shown good activity in conversion of xenobiotic compounds such as polycyclic hydrocarbons and trinitrotoluene. However, this biotechnologically promising fungus has not previously been studied at the molecular biology level. We show here that according to the molecular characterization of its main MNP isozyme, Nf b19 MNP2, and partial sequencing of its MNP3-, three lignin peroxidase- and two laccase-encoding genes, and the gene encoding the ribosomal SSU 18S RNA, that the fungus has a close phylogenetic relationship to the white-rot basidiomycete Phlebia radiata (Fr.). Ribosomal internal transcribed spacer (ITS) sequence (ITS1+5.8S+ITS2) phylogeny reclassifies Nf b19 as a possible representative of a new species of the genus Phlebia, nearest to the Phlebia acerina clade. The genus Phlebia belongs to a completely different family (Corticiaceae) and order (Aphyllophorales) within the phylum Basidiomycota than the genus Nematoloma, which is classified in the order Agaricales, family Strophariaceae. Our results thus indicate a need for systematic re-identification of the previously named N. frowardii isolate b19.

Culture independent PCR: an alternative enzyme discovery strategy

Degenerate primers were designed for use in a culture-independent PCR screening of DNA from composite fungal communities, inhabiting residues of corn stovers and leaves. According to similarity searches and alignments amplified clone sequences affiliated with glycosyl hydrolase family 7 and glycosyl hydrolase family 45 though significant sequence divergence was observed. Glycosyl hydrolases from families 7 and 45 play a crucial role in biomass conversion to fuel ethanol. Research in this renewable energy source has two objectives: (i) To contribute to development of a renewable alternative to world's limited crude fossil oil reserves and (ii) to reduce air pollution. Amplification with 18S rDNA-specific primers revealed species within the ascomycetous orders Sordariales and Hypocreales as well as basidiomycetous order Agaricales to be present in these communities. Our study documents the value of culture-independent PCR in microbial diversity studies and could add to development of a new enzyme screening technology.

야생초파리의 번식처로 이용되는 제주도산 버섯

1999년에서 2000년까지 해발 <TEX>$200{\sim}1000m$</TEX>에 이르는 제주도 한라산 일대에서 성숙한 야생버섯을 채취하여 야생초파리류가 번식처로 이용하는지의 여부를 조사하였다. 조사한 버섯 중에서 2목 12과 19속에 속하는 35종에서 초파리가 번식하였다. 이중 번식초파리가 동정된 버섯은 2목 8과 11개속에 속하는 14종이었다. 나머지 21종의 버섯에서는 초파리 유충(또는 번데기)만 발생하여 종이 확인되지 않았다. 35종 버섯중 34종은 주름버섯목(Agaricales)에 속하였고 노루털버섯(Sancodon scabrsoum) 1종만 민주름목(Aphylloprales)에 속하였다. 과 별 분포로는 35종 중 무당버섯과(Russulaceae)가 10종, 광대버섯과(Amanitaceae) 6종, 송이버섯과(Tricholomataceae)와 주름버섯과(Agaricaceae)가 각각 4종 그물버섯과(Boletaceae)가 3종 독청버섯과(Strophariaceae)가 2종 이었고 나머지 6과는 각 1종씩 이었다. 속 별로는 무당버섯속(Russula)이 8종, 광대버섯속(Amanita)이 6종, 주름버섯속(Agaricus)이 4종, 그리고 젖버섯속(Lactarius)의 2종순이었고 나머지 속은 각 1종씩 이었다. 버섯 크기별 초파리의 선호성은 갓의 지름이 5cm이상의 비교적 큰 버섯을 선호하였다. 버섯에서 번식하는 초파리는 총 14종이었고, 이중 버섯초파리속(Mycodrosophila)이 1종, 등초파리속(Hirtodrosophila) 이 5종, 그리고 초파리속(Drosophila)이 8종으로 가장 많았다. 두띠노랑초파리(Drosophila bizonata)와 여섯줄등초파리(Hirtodrosophilia sexvittata)는 6종의 버섯에서 번식하였고, 가시별초파리(D. unispina)가 3종, 기타 다른 초파리는 2종 흑은 1종의 버섯에서 번식하였다. 이번 조사의 결과와 여러 문헌을 종합해볼 때 이번에 밝혀진 것 보다 더 많은 종류의 버섯이 초파리와 번식적인 면에서 상관관계를 가질 것으로 판단된다. Wild Mushrooms collected in Mt. Halla of Jeiu Island around altitude of <TEX>$200{\sim}1000\;m$</TEX> from 1999 to 2000 were studied to investigate utilization as the natural breeding sites by wild drosophilids. Thirty-five mushroom species belonging to the 19 genera of 12 families from 2 orders were used as natural breeding sites by drosophilids. Adult flies emerged from 14 species of mushrooms belonging to the 11 genera of 8 families from 2 orders were identified. From the rest of 21 species of mushrooms, only larvae or/and pupae were reaped. Among 35 species of mushrooms, 34 species belonged to order Agaricales and only one species, Sarcodon scabrosum, belonged to order Aphyllophorales. In terms of composition of mushroom families, total 35 species belonging to 12 families were composed of 10 species of Russulaceae, 6 species of Amanitaceae, 4 species of each Tricholomataceae and Agaricaceae, 3 species of Boletaceae, 2 species of Strophariaceae and each one species of rest 6 families. Concerning the composition of the genus, 35 species belonging to 11 genera were composed of 8 species of Russula, 6 species of Amanita, 4 species of Agaricus, 2 species of Lactarius, and each one species of rest 7 genera. In terms of the mushroomsize preference of drosophilid flies for breeding sites, most flies preferred comparatively large mushrooms above 5 cm of pileus size in diameter, Fourteen species of drosophilids were identified as mushroom-breeding species. Among these, one and five species belonged to genera Mycodrosophila and Hirtodrosophila respectively, The genus Drosophila included the most abundant 8 species. Drosophila bizonata and Hirtodrosophila sexvittata bred on 6 species of mushrooms respectively, D. unispina bred on 3 species of mushrooms, rest species of Drosophila bred on one or two species of mushrooms. From the result of this study and other literatures, it could be presumed that much more mushroom species could serve as the natural breeding sites for greater number of drosophilid species than those examined in this study on Jeju Island.
