From: A new double right border binary vector for producing marker-free transgenic plants
Schematic map of the T-DNA region of the binary vector pMarkfree3.0 and insertion of the gus and nptII expression cassettes to create pMarkfree5.0. P35S, cauliflower mosaic virus 35S promoter; T35S, cauliflower mosaic virus 35S terminator; int-gus, β-glucuronidase gene with catalase intron; nos 3’, nopaline synthase gene polyadenylation signal; LB, left T-DNA border; RB, right T-DNA border; OD, overdrive sequence.
