Figure 3. The expression patterns of VND4 and VND5 in Arabidopsis stems and the root-hypocotyl region.

Figure 3

The expression constructs containing the VND4 and VND5 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, D) Cross sections of elongating internodes showing GUS staining (blue) for VND4 (A) and VND5 (D) only in developing vessels in the protoxylem. (B, E) Cross sections of non-elongating internodes showing GUS staining for VND4 (B) and VND5 (E) in developing vessels in the metaxylem. (C, F) Cross sections of the root-hypocotyl region showing GUS staining in developing vessels in the secondary xylem. co, cortex; if, interfascicular fiber; mx, metaxylem; px, protoxylem; sx, secondary xylem; ve, vessel; xf, xylary fiber. Bar in (A)  = 96 µm for (A) to (F).
