GUS expression of PHRE1:pMDC164, PHRE2:pMDC164, PHRE1:pMDC43, and PHRE2:pMDC43 in transgenic moso bamboo leaves using carbon nanotubes diffusion transformation. Photographs showing the stained mature and young leaves infiltered by (A, C-i-ii) PHRE1 and PHRE2 (pMDC164) and (B, D-i-ii) PHRE1 and PHRE2 (pMDC43). A, B, C, D – iii, and WT are PEI-SWNTs without plasmid DNA, and (WT) plasmid DNA, respectively. Scale bar represents 50 μm
