Introduction of Maize C4 Photosynthesis Enzyme Genes in Rice Plant

초록

Transgenic rice plants expressing the maize phosphoenolpyruvate caboxylase (PEPC) and pyruvate, orthophosphate dikinase (PPDK) exhibit a higher photosynthetic capacity (up to 35%) than untransformed plants. Results obtained with transgenic rice plants grown in both controlled environment and field showed that they tend to have a superior photosynthetic capacity, especially under high light condition, and exhibit up to 35% increases in grain yield. Under photoinhibitory and photooxidative conditions, PEPC transgenic rice plants are capable of maintaining a higher photosynthetic rate, a higher photosynthetic quantum yield by PSII and a higher capacity to dissipate excess energy photochemically and non-photochemically than untransformed plants.
