Schematic diagram of the chimeric BiP constructs transformed into tobacco via pBI121-derived binary vector. The soy BiP gene in the sense (A) and antisense (B) orientation was placed under the control of the constitutive CaMV 35S promoter (35S-P) and the 3′ nos polyadenylation signal (3′nos). The nptII gene expression is driven by the nos promoter (nos-P). LB and RB correspond to the T-DNA left and right borders, respectively. The positions of some restriction enzyme sites are indicated.
