S. commune in interaction with P. lilacinum CBS 150709, sampled from non-interacting edge
RNA was extracted with TRIzol (Thermofisher Scientific, USA) using the manufacturers protocol. Next, the sample was treated with DNAse I to remove genomic DNA and cleaned up using the RNA Cleanup protocol from the QIAGEN RNeasy Plant Mini Kit (QIAGEN, The Netherlands). Illumina libraries were generated for RNA-Seq and subsequently sequenced on the Illumina NextSeq 2000 platform in 2 x 50 bp mode (Utrecht Sequencing Facility; www.useq.nl).
