OsDof1 contributes to cold tolerance in LD5. Seed setting rates of non-transgenic (LD5 and LJ11) and transgenic lines under normal conditions and cold treatment were estimated. Data are shown as mean ± standard deviation of three plants for each line and under a specific condition (Supplemental Table 4). Asterisks indicate significant differences in seed setting rates between control and cold treatment conditions (Student’s t-test; *P < 0.05; **P <0.01; ***P<0.001)
