Fig. 10From: Transgene silencing of sucrose synthase in alfalfa (Medicago sativa L.) stem vascular tissue suggests a role for invertase in cell wall cellulose synthesisComparison of in situ neutral invertase activity measured in stem transverse-sections of elongating stem (ES) and post-elongation stem (PES) internodes of control (M22) and the MsSUS1 down-regulated line (M18). a ES internode of M22; (c), ES internode of M18; (e), PES internode of M22; (g), PES internode of M18. b, d, f, h are negative controls (no sucrose in the assay medium) for a, c, e, g, respectively.
