Delayed senescence of the u11-48k mutant plants. (A) Prolonged survival of the u11-48k mutant plants (amiR1-1, amiR1-2, and amiR1-3). Identical results were obtained from three independent experiments, for which a representative example is shown. (B) Dark-induced senescence. Rosette leaves from 4-week-old wild type (WT) and u11-48k mutants were floated on water in the dark for 4 d. (C) Chlorophyll content in the leaves of each plant was measured 4 d after dark-induced senescence. Values are means ±SE obtained from three independent biological replicates, two leaves per replicate, and asterisks above the columns indicate statistically different values between WT and mutant plants (P≤0.05).
