Abstract

I cloned the TA-iaaM gene, an auxin biosynthetic oncogene from A. vitis strain Tm-4, behind the 35S promoter of the cauliflower mosaic virus in an Agrobacterium binary plasmid. The presence of the gene in the resulting plasmid was confirmed with restriction digestion and PCR analyses. The construct was introduced into an Agrobacterium transformation vector, and transferred into Petunia hybrida cells by the leaf disc transformation method. The resulting transgenic plants exhibited morphological abnormalitites, including lancet shaped, downward curling leaves, and strong apical dominance, indicating the expression of the transgene, and the accumulation of excessive amounts of indole-3-acetic acid. Transgenic plants of normal morphological features have also been obtained. These latter plants may have an inactivated or silenced transgene.
