Vehicles and ways for efficient nuclear transformation in plants.

Transgenic science and technology are fundamental to the state-of-art plant molecular genetics and crop improvement. The new generation of technology endeavors to introduce genes ‘stably’ into ‘site-specific’ locations and in ‘single copy’ without the integration of extraneous vector ‘backbone’ sequences or ‘selectable markers’. Numerous plant transformation technologies have developed with the aim of achieving these objectives. Here we discuss some of these technologies, which can push the development of ‘better transgenic plants with desirable characters only’.
