CamCYC2A and CamCYC2B expression pattern in Lobelioideae species. A–D CamCYC2A expression pattern, E–F CamCYC2B expression pattern. A, E Lobelia erinus, B, F Lobelia siphilitica, C, G Lithotoma axillaris, D, H Lobelia polyphylla. Low saturation of color represents minor expression, high saturation of color represents high expression in flower buds. CamCYC2A is more highly expressed in species with relatively small dorsal corolla lobes, (A, B) while CamCYC2B is the more highly expressed in species with relatively large dorsal corolla lobes (G, H). CamCYC2A is weakly expressed in the dorsal corolla lobes (the true ventral domain) and is highly expressed in the ventral domain (the true dorsal domain). CamCYC2B has weak expression in the dorsal corolla lobes (the true ventral corolla lobes), medium expression in lateral corolla lobes, and high expression in the ventral corolla lobe (the true dorsal corolla lobe)
