Fungi of the genus are white-rot basidiomycetes widely studied because of their ability to synthesize high added-value compounds and enzymes of industrial interest. well because GMC oxidoreductases, copper radical oxidases along with other enzymes involved in the generation of extracellular hydrogen peroxide and iron homeostasis. Finally, we recognized the transcripts encoding all the enzymes involved in terpenoid backbone biosynthesis pathway, numerous terpene synthases related to the biosynthesis of sesquiterpenoids and triterpenoids precursors, and also cytochrome P450 monooxygenases, glutathione S-transferases and epoxide hydrolases with potential functions in the biodegradation of xenobiotics and the enantioselective biosynthesis of biologically active drugs. BMN673 To our knowledge this is the 1st report of a transcriptome of genus and a source for long term molecular studies in sp, and are basidiomycetes that cause wood decay by white rot. You will find four widely distributed varieties, and were explained by their ability to synthesize compounds of high added-value, including BMN673 flavors, antioxidants, antibiotics and antivirals [18]C[22] and as efficient suppliers of laccases along with other enzymes of industrial interest [23]C[31]. Although many of these enzymes -showing high thermal stability, broad pH range, and potential in biotechnological applications-, have been purified and characterized, there is a lack of exhaustive molecular studies and no BMN673 genomic or transcriptomic data is so far available for this genus. The ability of BAFC 2126, to selectively delignify loblolly pine (was able to reduce lignin content material in 11% in 14 days of treatment, and that wood suffered notable structural changes of lignin and hemicelluloses, as exposed from 13C CP-MAS NMR spectra. An increase of 15% in porosity BMN673 of decayed wood confirmed physical changes due to fungal attack. Therefore, this strain is usually potentially a candidate for use in softwoods biopulping processes. With this work we sequenced and analyzed the transcriptome of BAFC 2126. Since it was reported the addition of Cu2+ in tradition press induces the transcription of laccase genes in white-rot fungi [33], [34] and also the manifestation of additional enzymes such as Rabbit Polyclonal to MAEA glyoxal oxidase and manganese peroxidase [35], we evaluated the transcriptome of growing in press supplemented with copper sulfate. Our results provide the 1st reference transcriptome of the genus and a source for long term molecular studies in strain BAFC 2126 (BAFC: Mycological Tradition Collection of the Division of Biological Sciences, Faculty of Precise and Natural Sciences, University of Buenos BMN673 Aires) (Polyporaceae, Aphyllophorales, Basidiomycetes) was used in this study. Stock cultures were managed on malt draw out agar slants at 4C. Medium for fungal tradition (GA medium) contained 20 g glucose, 3 g asparagine monohydrate, 0.5 g MgSO4 7H2O, 0.5 g KH2PO4, 0.6 g K2HPO4, 0.09 mg MnCl2 4H2O, 0.07 mg H3BO3, 0.02 mg Na2MoO4 H2O, 1 mg FeCl3, 3.5 mg ZnCl2, 0.1 mg thiamine hydrochloride in 1 L of distilled water and supplemented with 1 mM CuSO4. Initial pH of the medium was modified to 6.5 with 1 N NaOH. Erlenmeyer flasks (500 ml size) containing 50 ml of medium were inoculated with four 25-mm2 surface agar plugs from a 7-day-old tradition produced on malt agar (1.3% malt extract, 1% glucose, 2% agar). Incubation was carried out statically at 28 1C. Cultures were harvested at stationary phase at day time 21. RNA extraction, cDNA synthesis and 454 pyrosequencing Fungal mycelium was filtered and immediately floor into good powder using liquid nitrogen. Total RNA was extracted using the RNAzol RT reagent (Molecular Study Center Inc., Cincinnati, USA) according to the manufacture?s instructions. The amount of RNA was estimated inside a Nanodrop ND-1000 spectrophotometer (Nanodrop Systems) and RNA quality was determined by formaldehyde RNA gel electrophoresis. Poly (A) RNA was purified from total RNA using Dynabeads oligo (dT) magnetic beads (Invitrogen Existence Systems, Carlsbad, USA) and mRNA was broken into fragments of 50 to 2000 nucleotides by treatment with RNA fragmentation buffer (0.1 M Tris-HCl, pH 7.0 and.
