From: Characterization of the REVEILLE family in Rosaceae and role of PbLHY in flowering time regulation
Circadian expression patterns of PbRVE genes under constant light conditions. The time of the light beginning to turn on was defined as zeitgeber time zero (ZT 0). Starting from ZT1, leaves were harvested every 4 h for a total of 18 times over three days. White and gray areas indicate subjective day and subjective night, respectively. PbUBQ was used as an internal control. The highest expression level of each gene was set to 1 for standardized calculation. Error bars represent the standard error
