Cauliflower nuclear transformation plasmid was constructed using pBluescript (3 kb) , an hptII cassette (2.9 kb) from pCAMBIA1303 and a BoMinD cassette (3 kb) from pNAV42 + BoMinD . Firstly, the hptII cassette from pCAMBIA1303 was cloned into pBluescript using SacI and SacII restriction enzymes, then the BoMinD cassette from pNAV42 + BoMinD was cloned into pBluescript + hptII using XbaIand Asp7181 restriction enzymes
