Structure of the NR antisense gene inserted into the EcoRI site of pBin 19 (Bevan, 1984). The tomato NR gene (0.714 kb) was placed in the antisense orientation relative to the CaMV 35S promoter (CaMV 35S Pro), upstream of the CaMV 35S terminator sequence (term). Relative positions of additional restriction endonuclease recognition sites are shown.
