Abstract: With improved transgenic technology, there is great potential for bio-fortification of crops. For complex agronomic traits controlled by multiple genes, single gene transformation is insufficient, and multi-gene engineering is limited to technical factors. Regulation and expression of metabolic modification and a series of related genes is more difficult to break through. Recently, Chinese scientists successfully engineered sophisticated anthocyanin biosynthesis in rice endosperm, which suggests the potential utility of the TransGene Stacking II System for synthetic biology and improving agronomic traits in crops.
