Transgenic plants are

  • produced by a somatic embryo in an artificial medium

  • generated by introducing foreign DNA into a cell and regenerating a plant from that cell

  • Produced by protoplast fusion in the artificial medium

  • grown in the artificial medium after hybridization  in the field


B.

generated by introducing foreign DNA into a cell and regenerating a plant from that cell

The plants obtained through genetic engineering contain a gene or genes usually from an unrelated organism, such genes are called transgenes and the plants containing transgenes are known as transgenic plants. These plants are often called as genetically modified or GM crops, eg, Flavor saur transgenic for identification, expressing the gene activity in time to produced several chemicals likes fatty acids sugars cellulose, rubber, etc.
