strain: QM9414 tissue: mycelia medium: growth on lactose for 28 hrs
Treatment protocol
Mycelia from both stages were freeze-dried and ground in liquid nitrogen using a mortar and pestle. For each of the two experimental conditions, five independent replicates of mycelium were mixed.
Growth protocol
Trichoderma reesei strain QM9414 (ATCC 26921) was grown in duplicate grown in 1 l Erlenmeyerflasks flasks on a rotary shaker (250 rpm) at 30 C in the medium described by Seiboth et al. (2004) [Mol Microbiol 51:1015-25] with lactose, glucose and glycerol (each two flasks) as a carbon source at a final concentration of 10 g l-1.
Extracted molecule
total RNA
Extraction protocol
Total RNAs were extracted using TRIzol® reagent (Invitrogen Life Technologies, Carlsbad, CA, USA), according to the manufacturer's instructions, and then purified using the RNeasy MinElute Cleanup Kit (Qiagen, Hilden, Germany). The RNA quality and quantity were determined using a Nanodrop spectrophotometer.
