Germination performance and At3g08030 expression of W. urens seeds. (A) Cumulative germination curves of 6–8-week seeds (C) and 12-month aged seeds (A) under optimal conditions and 6–8-week seeds (CS) and 12-month aged-seeds (AS) under stress conditions (50 mm NaCl). (B) Maximal germination rate of C, A, CS and AS seeds. (C) RT-PCR analysis of At3g08030 expression was performed in the different seed lots from W. urens. Expression of ACT7 was analysed simultaneously as an internal standard (lower panel). Letters indicate statistical differences between the germination curves. All the experiments were performed at least three times.
