Fig. 8From: Over-expression of poplar NAC15 gene enhances wood formation in transgenic tobaccoPhloroglucinol staining of tobacco plants. The staining color was obviously deeper in the TLs than that in the CL. And the three TLs showed three levels of staining color, which indicates three levels of lignification. TL1, 3, 5, transgenic lines; CL, control line; E, epidermis; C, cortex; VB, vascular bundlesBack to article page
