Global gene expression analysis of cacao embryogenesis. (A) Representative images of zygotic and somatic embryo stages used for RNA extraction. Zygotic Embryos at stages: Torpedo, Early-Full, Late-Full, Mature. Somatic Embryos at stages Late Torpedo and Mature. (B) Global gene expression Heatmap and Cluster analysis of cacao zygotic and somatic embryo samples. Cluster analysis on Y axis represents similarities in overall gene expression profiles while cluster analysis on the X axis (above) indicates the relatedness of gene expression profiles between the different tissue samples. The log₂ of relative gene expression levels are depicted in color values indicated by the color key at bottom right.
