Table 1 Number of differentially expressed transcripts (DETs) per pairwise comparison among E. fulgens (F), E. puniceoluteum (P) and hybrids (H) in allopatry and sympatry (ICO and ICA). The number of up-regulated and down-regulated transcripts refer to either E. fulgens (F) or E. puniceoluteum (P) in each comparison
