Introduction:

• Genetic engineering/recombinant DNA technology is the direct manipulation of an organism’s genome using biotechnology.
• Genetic engineering is a process in which recombinant DNA (rDNA) technology is used to introduce desirable traits into organisms.
• A plant in which a foreign gene has been transferred through genetic engineering is called transgenic plant and the gene so transferred is called transgene.

Steps involved:

a) Identification and isolation

b) Introduction

c) Integration

d) Selection and expression

e) Regeneration

f) Transmission.
