Fig. 3From: Transgene silencing of sucrose synthase in alfalfa (Medicago sativa L.) stem vascular tissue suggests a role for invertase in cell wall cellulose synthesisSucrose synthase activity in stem internodes. Activity was measured in internodes of control (M22) and the lines containing the PEPC7-P4::MsSUS1 construct (M17, M18). a elongating stem (ES) internodes. b post-elongating stem (PES) internodes. Values represent means ± standard error (n = 3). Asterisk indicates SUS activity was at the limits of detectionBack to article page
