Schematic representation of constructs used to generate transgenic tobacco plants. TE, Translational enhancer from the tobacco tCUP promoter. PR1b, Secretory signal peptide from the pathogenesis related protein 1. eGFP, Enhanced green fluorescent protein. L, Linker (GGGS)3. HFBI, Hydrophobin I tag. ELP, Elastin-like polypeptide tag. StrepII, Fusion tag for detection and purification of recombinant protein. KDEL, ER retention peptide. Size of each element of the DNA constructs is not proportional to the actual sequence length [14, 30].
