Patterns of differential gene expression among Epidendrum fulgens, E. puniceoluteum and their hybrids. Sample correlation matrix heatmaps for differentially expressed transcripts in comparisons between E. fulgens (in blue) and E. puniceoluteum (in orange) from allopatric populations (a), and among E. fulgens, E. puniceoluteum and hybrids (in black) from ICA (b) and ICO (c) sympatric zones
