Plant biotechnology is the study of techniques, methods and processes that are adopted and applied to plants generally for genetic manipulation for attaining plant verities with advantageous characteristics that have greater utility in industrial, agricultural, chemicals, pharmaceuticals and other purposes. Through biotechnology not only the variety is improved, but yield also improves through growing crops having resistance to diseases, herbicides and pesticides. Through understanding basic concepts of plant biotechnology and adopting improved genetically mutated seed verities, the grower as well as the consumer is benefited a great lot. “Plant Biotechnology” presents all the latest techniques of plant tissue culture, transformation and bioengineering at the outset and discuses in detail various issues of plant breeding, cloning, diseases resistances, herbicide and pest resistance. The book makes elaborate presentation on radiommunoassays, enzyme immunoabsorbent assays, genetic recombination, pharmaceutical products and solar energy that have immensely impacted the field of biotechnology. The book provides tremendous utility to students, teachers, researchers, farmers and general readers.
