Defects of p5cs2-1 mutants in reproductive development. A: Time till bolting (bolts longer than 1 cm) in long-day (LD) and short-day (SD) conditions. B: Leaf number at the onset of bolting of plants cultivated under short-day conditions in the greenhouse. C: Representative flowers of wildtype and p5cs mutant plants cultivated under long-day conditions. Error bars in A and B indicate SD of 8≤N≤12 individuals; * indicates significant difference from Col-8 (p<0.05 by students t-test).
