Altered Lignin Deposition in the Roots of WRKY15OE and WRKY15-EAR Transgenic Seedlings.
(A) Lignin accumulation in 7-d-old Col-0, WRKY15OE (line no. 8), and WRKY15-EAR (line no. 38) roots was detected by phloroglucinol-HCl staining. Images were taken using a Nikon microscope.
(B) Basic fuchsin (BS) staining of lignin in the roots of 7-d-old Col-0, WRKY15OE (line no. 8), and WRKY15-EAR (line no. 38) seedlings. DIC and fluorescence images were photographed using a Nikon C2 Plus LSCM. The white long bracket represents a gap in protoxylem vessels. Scale bar = 50 μm.
