Fig. (1) Schematic diagram of plasmid constructs pCAM-35S-LF, pCAM-Act-LF and pCAM-ActM-LF. Plasmid constructs in the vector pCAMBIA1300 (8958 bp, accession number AF234296) with a porcine lactoferrin (LF) cDNA fragment (2061 bp, accession number NM214362) driven by A) the cauliflower mosaic virus (CaMV) 35S promoter (850 bp, 35S-P) and B) a rice actin promoter (1255 bp, Act-P) and 3’-NOS terminator (300 bp) were created for rice transformation. C) In the pCAM-ActM-LF construct, a tobacco RB7 MAR DNA fragment (1100 bp, accession number U67919) was added upstream of the actin promoter.
