The table contains the number of total transcripts, high-count transcripts and low-count transcripts available for differential expression analyses in the complete dataset (i.e. no data filtering applied) or following data filtering based on a reads-present (RP) criterion or a counts per million (CPM) criterion. Also listed are number of transcripts with expression levels present in sand bluestem and absent in big bluestem (SB-only transcripts), and transcripts with expression levels present in big bluestem and absent in sand bluestem (BB-only transcripts)
