EXPA Expression and Function during Seed Germination

(A) Heatmap showing expression of the EXPA gene family in germinating seeds at different time points after imbibition (0, 1, 3, 6, 12, and 24 h) [7].

(B) Expression of the EXPA gene family in the radicle (R) and micropylar endosperm (M) at 16 h after imbibition [25].

(C) Germination of XVE::EXPA9 seeds on water and in the presence of 10 μM GA-synthesis inhibitor PAC. Ectopic expression of EXPA9 is induced after the application of 30 μM β-estradiol (+E). Data are expressed as mean value ± standard deviation (SD) (n ≥ 50 seeds per biological replicate).
