An overview of genetic engineering of PEPC, PPDK and NADP-ME enzymes from C4 plants to C3

摘要

PEPC, PPKD and NADP-ME are the most important enzymes in the C4 pathway of photosynthesis which have introduced into C3 plants to increase efficiency of photosynthesis. In this paper the strategy of introduction of the intact C4-specific gene into C3 plants would be expected to lead to high level and cell-expression of C4 enzymes in mesophyll cells. By contrast, over expression of enzymes specific of bundle sheath cells, conventional techniques with gene constructs containing a strong promoter fused to a cDNA were effective.
