The pCambia vector backbone is derived from the pPZP vectors. The pCambia1300 vector offers:1.high copy number in E.coli for high DNA yields2.pVS1 replicon for high stability in Agrobacterium 3.small siz 4.restriction sites for modular plasmid modifications and small but adequate polylinkers for introducing DNA of interest 5.bacterial selection with kanamycin 6. plant selection with hygromycin B
