Growth and development of plants modified in GRXS17 expression as a function of photoperiod and temperature. A, Five-week-old plants grown in standard conditions (8-h photoperiod and 200 µmol photons m⁻² s⁻¹) at 22°C. B, Plants grown for 2.5 weeks in standard conditions and transferred to 28°C (8-h photoperiod and 200 µmol photons m⁻² s⁻¹) for 2.5 weeks. The arrow indicates the absence of young leaves. C, Plants grown in long-day photoperiod conditions (16 h and 200 µmol photons m⁻² s⁻¹) at 22°C. D, Plants grown for 2 weeks in standard conditions and transferred to continuous light (200 µmol photons m⁻² s⁻¹ and 22°C) for 3 weeks. E, Plants grown for 2 weeks in standard conditions and transferred to 28°C and long-day photoperiod (16 h and 200 µmol photons m⁻² s⁻¹) for 2.5 weeks. F, Plants grown for 3 weeks in standard conditions and transferred to 15°C and long-day photoperiod (16 h and 200 µmol photons m⁻² s⁻¹) for 4 weeks. grxS17, Homozygous SALK_021301 plants; grxS17 3.3 and 17.8, two independent grxS17 lines expressing GRXS17; LD, long (16-h) day; SD, short (8-h) day; WT, wild type.
