SPS enzymatic activity in the different SPS knock-out genotypes compared with the Col0 wild-type control. Samples were taken from leaves of 6-week-old plants cultivated under short-day conditions. Samples were harvested 6h into the photoperiod. Values represent the mean ±SD (n=4). An asterisk indicate a significant difference at P<0.05 as analysed by t-test.
