Figure 2. The expression patterns of VND1, VND2 and VND3 in Arabidopsis stems.

Figure 2

The expression constructs containing the VND1, VND2 and VND3 genes linked with the GUS reporter gene were transformed into the Arabidopsis plants and the first generation of transgenic plants was examined for GUS activity. (A, C, E) Cross sections of elongating internodes showing GUS staining (blue) for VND1 (A), VND2 (C) and VND3 (E) only in developing vessels in the protoxylem. (B, D, F) Cross sections of non-elongating internodes showing GUS staining for VND1 (B), VND2 (D) and VND3 (F) in developing vessels in the metaxylem. co, cortex; if, interfascicular fiber; mx, metaxylem; px, protoxylem. Bar in (A)  = 115 µm for (A) to (F).
