Fig. 3From: Differential gene expression reveals mechanisms related to habitat divergence between hybridizing orchids from the Neotropical coastal plainsPatterns 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 zonesBack to article page
