Transformation: transformation means direct absorption, incorporation and expression of foreign genetic material from the surrounding environment (S.Cohen et al.,1980) Transformation in plants: the processes of creation in plants of a transgenic plant introducing new genes into an organism is known as transformation. (Wiley Black Well Encyclopedia of Life) Why do we need transformation? The three main challenges facing humanity in today's century are food, energy and the environment. Plant life is a major factor in all three of these problems. Photosynthetic plants are the main source of energy and food. Plant research has sought to provide solutions to these challenges. The basic biology of plants is similar to ours. However, their forms and lifestyle are fundamentally different. Plants can survive up to 5000 years; they can obtain nutrients from the air and soil and resist environmental stress and pest attacks (David w.Ehrharth, 2012) But with the increase in pollution, overpopulation etc. Plant lives are in danger and as a result, in fact, humans are in danger. So, for the survival of both, scientists have worked very hard and discovered various techniques to transform the genetic material of plants so that they can protect themselves and increase their yield. Purpose of transformation: The main purpose of transformation in plants is:• Production of disease-free plants • Improve quality of plants • Improve quantity i.e. productivity • Environmentally friendly plants • Drought and salt resistance in plants • value-added characteristics • For experimental use Requirements for processing: The processing procedure should be: • Easy • Economical • Hazardous procedures and harmful substances should be avoided • Technical simplicity should...... half of the paper ... ...of its export into the cytoplasm by the host RNA export machinery viral vectors that not only replicated well in infected cells but also were transported by Agrobacterium T-DNA more effectively. Genetically modified plants are already a vital part of modern agriculture. The development of new technologies for the stable and transient expression of recombinant proteins in plants could potentially provide more versatile biotechnological tools for the scientific and commercial communities (Trends in Plant Sciences Vol xx no xx Month 2005)(THE END)
