Abiotic stress responses of the sic-1 mutant plants. (A) Chilling stress response of WT and sic-1. Seeds were germinated and grown on MS medium supplemented with 3% sucrose at 22 °C for 3 wk (Upper) or at 4 °C for 5 wk (Lower). (B) WT and sic-1 seeds were germinated and grown in soil at 22 °C for 3 wk, then transferred to and grown at 4 °C for 2 mo. Inset: Top view of the sic-1 under cold stress. (C) Chilling stress response of sic-1, se-1, and abh1-285. (D) NaCl stress response of sic-1, se-1, and abh1-285. Six-day-old seedlings were transplanted on to MS medium supplemented with 3% sucrose (Left) or with 3% sucrose with 150 mM NaCl (Right) and grown for 3 wk.
