Figure 6From: Identification, cloning and characterization of an ultrapetala transcription factor CsULT1 from Crocus: a novel regulator of apocarotenoid biosynthesis Transactivation analysis of CsULT1 by β-galactosidase assay. Vec represents empty vector control and ULT-1 and ULT-2 represent two independent colonies used for the assay. Values are taken as average of three independent experiments of the transformants and presented as fold increase in activity.Back to article page
