The pCAMBIA2300 binary vector was modified by adding Gateway recombination sites for fast gene transfer between vectors and the maize polyubiquitin promoter Ubi-1 (ZmUbi1), which is known to drive high gene expression levels in monocots.

pGVG: a new Gateway-compatible vector for transformation of sugarcane and other monocot crops.The successful development of genetically engineered monocots using Agrobacterium-mediated transformation has created an increasing demand for compatible vectors.  The pCAMBIA2300 binary vector was modified by adding Gateway recombination sites for fast gene transfer between vectors and the maize polyubiquitin promoter Ubi-1 (ZmUbi1), which is known to drive high gene expression levels in monocots.
