MADS12 overexpression promotes early bud break of ecodormant poplars. Bud break scoring of hybrid poplar MADS12 overexpressing OE3 and OE5 lines and wild type after transferring to LD and 22°C conditions (A,B) with chilling treatment and (C,D) without chilling treatment. (B,D) Representative picture of bud break differences in (B) plants after 15 days of LD exposure and (D) plants after 10 days of LD exposure. Values represent the mean of the bud score measure of n = 10–15 plants. Significant differences between overexpressing (OE) and wild type (WT) were analyzed using Tukey test, *p < 0.05. Top panels indicate photoperiodic and temperature conditions used.
