Fig. 6From: Genome-wide identification of grain filling genes regulated by the OsSMF1 transcription factor in riceTranscriptional activity analysis of OsSMF1 in rice protoplast using a dual luciferase assay system. a Construction of reporter (Rc), effector (Ec), and internal control (Icc) vectors. b P35S:SMF1 and P35S:rLUC constructs were co-transfected with TRX:fLUC, HRGP:fLUC or α-Glb:fLUC into rice protoplasts. rLUC was used as an internal control. The data are presented as the mean ± SD (n = 3)Back to article page
