Expression patterns of OsGRPs. (A) Total RNA was extracted from 4-week-old rice seedlings and the relative expression levels of six OsGRPs were analysed via real-time RT-PCR. OsGRP transcript levels are presented as the relative values to the expression of OsGRP2. (B) Expression patterns of OsGRPs in rice subjected to cold stress (4 °C) for 6, 12, 24, 48, and 72 h were analysed via real-time RT-PCR and presented as the relative expression (fold) of the non-stressed controls. The mean values and standard errors (bar) were obtained from three independent experiments.
