Effects of tetracycline on wild-type and inducible P35So IPT-5/TETR transgenic tobacco plants

Introduction of the Agrobacterium ipt gene, coding for isopentenyl transferase,undercontrol of a tetracycline (Tc)-inducible promoter results in avery specificsystem in which cytokinin levels can be changed. Because Tc belongs to thegroup of antibiotics that affect 70S ribosomes, itis important to study the effectsof Tc on untransformed plants. Although 1 mg l
