Figure 4.

Relative expression levels analysis of transcripts negatively associated with dormancy release (NCED, ABI2, PP2C, ARP3, ARP7, DRM) levels in the Embryo (Em□) and endosperm (En■) under warm (20°C)/cold (4°C) seed stratification process. RS, radical just sprouted; RG, radical growing up to 2 cm. Expression is shown relative to GAPDH as the reference gene. RNA was extracted from three biological samples and qRT-PCR was performed. Data represent means ± SD. * indicate a significant difference between Em and En at P < 0.05.
