  • Title: ipt Gene transformation in petunia by an Agrobacterium mediated method.
    Author: Bai LJ, Ye CJ, Lu JY, Yang DE, Xue H, Pan Y, Cao PX, Wang B, Liu M.
    Journal: J Immunoassay Immunochem; 2009; 30(2):224-31. PubMed ID: 19330647.
    Abstract:
    To prevent leaf senescence of petunia, the cytokinin biosynthetic gene isopentenyl transferase (ipt) was placed under the control of 35S promoter and introduced into petunia. PCR analysis showed an expected 0.5 Kb fragment of ipt gene in transgenic petunia. RT-PCR analysis indicated the expression of ipt gene in the transgenic lines. Leaves from transgenic plants remained green and healthy in normal culture condition, while the non-transformed plants turned to yellow. Transgenic plants showed a reduction in height and smaller leaf sizes. In transgenic lines, the internodes were shorter, and the roots grew slower than the non-transformed plants.
