Senescence delay in detached leaves of WT Pelargonium zonale and pSAG12::ipt transgenic plants. Detached leaves of control (left) and pSAG12::ipt (right) plants at 0 (a), 6 (b), 8 (c), 17 (d), 22 (e), 24 (f), 27 (g) and 34 (h) days of incubation in darkness. (i) Mean concentration (±SE) of chlorophyll a + b (mg/g fresh weight) from detached leaves of control (WT) and pSAG12::ipt (TRG) plants at 0, 6 and 8 days of incubation in darkness. (j) Senescence delay of detached leaves from pSAG12::ipt plants. Fresh weight changes in detached leaves of WT P. zonale and a transgenic line carrying the pSAG12::ipt chimaeric gene over the time course analyzed. Data are the means of sixteen leaves ± SE. Bars: 1 cm.
