Structure diagram of transgenic vectors.

Ser1, Ser1-2 k and Ser1-4 k indicate the ~0.5 kb, ~2 kb and ~4 kb of Ser1 gene 5′-flanking sequence, respectively. The 2×, 3× and 4× Ser1 represent 2, 3 and 4 copies of Ser1 proximal promoter, respectively. RLuc, renilla luciferase; FLuc, firefly luciferase; A3, Bombyx mori A3 cytoplasmic actin gene promoter; EGFP, enhanced green fluorescence protein; SV40, 3′-untranslated sequences; ITR, inverted terminal repeats of PB transposon.
