The onset of the DE response is photoperiod dependent. A, Rosette leaf mean number of wild-type (WT) plants and flowering time mutants grown under SDs. Plants were subjected to normal-watering (NW; black bars) or low-watering (gray bars) regimes. Error bars represent se (n = 15). B, Quantification of the DE response for each genotype detailed in A expressed as relative leaf number variation (RLNV). Error bars represent se. Student’s t test values are as follows: *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001, ^NSP > 0.05, not significant. C, Rosette leaf mean number of wild-type plants and flowering time mutants grown under LDs. Plants were subjected to normal-watering (black bars) or low-watering (gray bars) regimes. Error bars represent se (n = 15). D, Quantification of the DE response for each genotype detailed in C expressed as relative leaf number variation. Error bars represent se. Student’s t test values are as follows: ***P ≤ 0.001, ^NSP > 0.05, not significant. E to H, Images of representative plants of the indicated genotypes grown under SDs and subjected to normal-watering or low-watering regimes. Wild-type Col-0 plants are 16 weeks old (E), svp-41 plants are 8 weeks old (F), wild-type Ler plants are 12 weeks old (G), and 35S:GI plants are 7 weeks old (H). Bars = 1 cm.
