The aim of this study was verify the use of fragment DNA as vector for genetic transformation of bean in order to replace circular vectors containing antibiotic resistance genes. The 1.5 kb DNA fragment carrying the bar gene was used to generate transgenic bean plants through microparticles bombardment. The frequency of bean transformation achieved was compared with transformation using the entire circular plasmid. The results have demonstrated that the transformation frequencies were similar. For the variety Carioca the frequencies were 0.8% (using DNA fragment) and 0.7% (using circular vector). For the variety Olathe the frequencies were 0.2% (using DNA fragment) and 0.3% (using circular vector). In addition, Southern blot analyses revealed similar pattern complexity in transgenic plants obtained either with the entire plasmid or DNA fragment. |
