3.4 The expression of flowering-related genes dramatically influenced in oslhy mutants
As OsGI and OsELF3 are also important regulators on photoperiodic flowering pathways in rice (Hayama et al., 2003; Izawa et al., 2011; Yang, Peng, Chen, Li, & Wu, 2013) and the expression of OsGI andOsELF3 was obvious affected in the oslhy mutant. Therefore, the expression of flowering-related genes (Hd1 ,Ehd1 , Ghd7 , Hd3a and RFT1 ) was further investigated (Figure 4). As expected, the expression of Hd1 andGhd7 was dramatically increased, while Ehd1 , Hd3aand RFT1 was dramatically decreased in oslhy mutations under LD conditions (Figure 4A). Under SD conditions, the expression ofGhd7 was increased, and Hd1 , Ehd1 , Hd3a andRFT1 was not significantly affected in oslhy mutations (Figure 4B).
