Transcriptomic methods

This section covers novel experimental and analytical approaches for transcriptomic, epigenetic, and related high-throughput genomic studies. Studies which use transcriptomic and high-throughput genomic methods, but which do not present a novel methodological approach, should be submitted to the section in the journal relating to the organism studied.
