Figure 2From: Improvement of photosynthesis in rice (Oryza sativa L.) by inserting the C4 pathwayVariation in leaf vein density between C3 and C4 plants. Vein density of (A) C3 (Oryza sativa L., rice variety IR64), (B) C4 (Setaria viridis) and (C) C4 (Sorghum bicolor) leaf sections. Rice has low vein density compared to the C4 plants like S. viridis and sorghum.Back to article page
