During the latest fifteen years a great progress has been achieved on transgenic research of the main crops including soybean, maize, rice, and wheat. Almost all the transformation techniques have been successfully used in these main crops. Especially for the Agrobacterium mediated transformation, not only successes it in soybean, a recalcitrant dicot plant to transformation, but also in rice, maize and wheat of monocot plants.
