“C” represents “control”, “T” indicates samples taken immediately after each cold treatment, and “R1” and “R3” indicate samples taken after post treatment recovery culture for 1 and 3 days, respectively. Values in the same row marked with different letters are significantly different, while an asterisk means that the value in Arabidopsis is significantly different from that in rice (p < 0.05). Values are means ± S.D. (n = 4 or 5)
