GUS activity and histochemical analyses of transgenic Arabidopsis plants. (A). Log-transformed values of GUS activity of T2 plants harboring Ichihime or KAS γ-TMT3 promoter are shown. Each blue dot represents value of independent T2 plant. Red dots represent T2 plants with the highest GUS activity, Ichihime 25-2 for Ichihime promoter and KAS 18-4 for KAS promoter. Black bar represents average value of T2 plants. (B). GUS histochemical anlaysis of leaves from T2 plant harboring Ichihime γ-TMT3 promoter (Ichihime 25-2) and T2 plant harboring KAS γ-TMT3 promoter (KAS 18-4).
