Figure 3From: The 5′UTR-intron of the Gladiolus polyubiquitin promoter GUBQ1 enhances translation efficiency in Gladiolus and ArabidopsisHistochemical GUS staining of transgenic (A) Gladiolus and (B) Arabidopsis plants containing the uidA gene under control of either the CaMV 35 S (35 S), G1-1 or G1-3 promoter. The Gladiolus plant material was taken three weeks after subculture from plantlets growing in vitro on MS medium. Plant tissue was incubated 16 h at 37°C in the staining solution. Magnification bars in A represent 2 mm.Back to article page
