design: RNA-seq was carried out at the Center for Genomic Technologies of the Engelhardt Institute of Molecular Biology, Russian Academy of Sciences. Transcriptomic libraries were prepared from 0.2 g of total RNA using the TruSeq Stranded mRNA Library Prep Kit (Illumina, USA) according to the manufacturers protocol. After enzymatic reactions, cDNA fragments were purified on MagPure A4 XP magnetic particles (Magen, China). The concentration of the libraries was measured on a Qubit 4.0 fluorimeter, and the size of the fragments was assessed using automatic capillary electrophoresis on an Agilent 2100 Bioanalyzer. Sequencing was performed on NextSeq 2000 in paired-end read mode.
