Fig. 4

Comparison of in situ sucrose synthase activity in stem transverse-sections of elongating stem (ES) and post-elongating stem (PES) internodes of control (M22) and the SUS down-regulated (M18) transformant. Purple coloration in cells indicates enzyme activity. a ES internodes of M22; (c), ES internodes of M18; (e), PES internode of M22; (g), PES internode of M18. b, d, f, h are negative controls (no sucrose in assay medium) for a, c, e, g, respectively. Abbreviations: PF, phloem fibers; P, phloem; C, cambium; XV, xylem vessel
