162 μM, Na2MoO4 4.86 × 10−2 μM; (c) Vitamins: Biotin 8.19 nM, Folic acid 4.53 nM, Thiamine hydrochloride (B1) 0.148 μM, Riboflavin 0.133 μ M, Pyridoxine hydrochloride (B6) 48.6 μM, Cyanocobalamin (B12) 7.38 × 10−2 nM, Nicotinic acid 40.6 nM, D-Calcium pantothenate 20.9 nM, p-Aminobenzoic acid 36.5 nM, Thioctic acid 24.2 nM. The pH of the basal elements solution was adjusted to 4.5 with 20% (m/v) NaOH. Trace elements and vitamins were prepared in 10000-fold concentrated stock solutions and added to the basal solution after autoclaving Fedratinib chemical structure at 120°C for 20 min. Analysis by qPCR of Phanerochaete chrysosporium AAD1 gene expression The expression of Pc AAD1 during Nitrogen-limited cultivation was analyzed by real-time

PCR (qPCR). The frozen mycelia were disrupted with TissueLyser II grinder for 2 x 1.5 min at 30 s−1 frequency (Qiagen SAS, Courtaboeuf, France) and total RNA was purified from c.a. 100 mg wet-mycelium with the RNeasy Plant Mini Kit (Qiagen) according to the manufacturer’s instructions. The quality of the extracted RNA was determined using the Bioanalyzer 2100 with the RNA 6000 Nano LabChip kit (Agilent Technologies, Massy, France) and quantified in the MAPK Inhibitor Library cost NanoDrop ND-1000 UV-visible light spectrophotometer (Fisher Scientific SAS, Illkirch, France). cDNA was then synthesized from an exact amount of 1 μg total RNA in 20 HDAC activity assay μL reaction mixtures using the iScript™ cDNA Synthesis Kit (Bio-Rad,

Marnes-la-Coquette, France). Real-time PCR reactions were carried out using a MyiQ Single-Color Real-Time PCR Detection System (Bio-Rad). The β-Tubulin transcript coded by scaffold_10:459524–461702 was amplified in parallel with the target AAD1 cDNA and used as reference for normalization Progesterone of gene expression. The stable Ct values observed for this gene among the different samples reflects the stability of its expression under the conditions tested. Primer sequences were as follows:

AAD1-2-3-F2 (5′-TCGTTGCTACCAAGTACAGTCTGGTCTACAAACGGGG-3′) and AAD1-3-4-R2 (5′-GCGATGGCCATCCCTTCGTGAATGCACA-3′) for target gene Pc AAD1;x BTUB-N-Term-F (5′-ATCGGTGCCAAGTTCTGGGAGGT-3′) and BTUB-N-Term-R (5′-TGTTCGCGCCAACTTCGTTGTAGT-3′) for reference gene. Reactions were performed in 25 μL final reaction volume using iQ™ SYBR® Green Supermix (Bio-Rad), 0.1 μM final concentration of each primer and 1 μL of the cDNA preparation. The qPCR conditions were as follows: 1 cycle (95°C for 3 min), 40 cycles (95°C for 16 s, and 58°C for 30 s). Reactions were set up in triplicate for each of four biological replicates to ensure the reliability of the results. The absence of genomic DNA in RNA samples was checked by real-time PCR before cDNA synthesis. Melting curves (55-95°C, in 0.5°C increments for 30 s) were performed at the end of the qPCR reaction to verify the specificity of the amplification products and the absence of primer dimers.
