Histochemical GUS assay of transgenic W. globosa via Agrobacterium-mediated stable transformation after the 4 weeks of selection. (A) TCS::GUS transformed W. globosa transgenic fronds (B) TCS::GUS transformed W. globosa transgenic frond showing GUS expression in both mother and daughter frond. (C,D) GUS positive daughter frond comes out from the single side pouch of the stably transformed mother frond. (E,F) Cross sections of transgenic W. globosa via Agrobacterium-mediated stable transformation after histochemical GUS assay. TCS::GUS transformed W. globosa transgenic frond showing GUS staining in both mother and daughter frond. MF, Mother Frond; DF, Daughter Frond; Scale bars (A–D) - 250 μm, (E,F) - 50 μm.
