 INTRODUCTION  PURPOSE  METHODS 1.Vectors mediated transformation 2.Direct gene transfer/ without vector Transformation

 Plant transformation is the technique or way to integration and expression of desire gene or DNA fragment in plant cell for improvement plant breed is known as plant transformation.  Transformation involving integration of introduced gene in the plant nuclear genome

 The improvement to crop plants and other plants for desire purposes like production of diseases free plants, improve quality of plants, improving quantity (product), salt, drought resistant plants.  And other purpose of this technology is used as an experimental tool for plant physiology and to study research work.

Vectors mediated transformation- plasmids or viruses used as vectors. Example-  Cauliflower mosaic virus (CaMV),  tobacco mosaic viruses
