Histochemical GUS analysis of leaf, stem, and root of T0 stable transgenic rice containing each of the three green tissue-specific promoters at the seedling stage. Stable transgenic rice containing each of the promoters of PvUbi2, ZmUbi1, and CaMV 35S were used as the positive controls. The histochemical GUS assay was conducted on at least 10 transgenic lines with the representatives being shown
