Tobacco: Overview

What is Agricultural Biotechnology?

Agricultural biotechnology, in its most general sense, refers to any technique that manipulates plants or animals (or their products) to achieve a specified goal. By this broad definition,picture of double helix DNA improvement of food crops and animals through selective breeding, and processes such as beer/wine fermentation, cheese production, and manufacturing of cloth from wool or cotton are examples of agricultural biotechnology. However, the term "biotechnology" is most often linked to modern science, and includes topics such as molecular breeding, tissue culture techniques, and recombinant DNA technology -- the latter often referred to as genetic engineering or genetic modification.

Plant genetic engineering involves inserting a gene (or sequence of genes), copied from a bacteria, virus, plant, animal, or human, into a plant. The gene of interest is often referred to as a "transgene", if the gene moves across species; the genetically modified plant is known as a "transgenic" plant or more generally as a genetically modified organism (GMO).

The purposes for genetically modifying crops using recombinant DNA technology fall into a few broad classes:picture of plant parts in a petri dish

  1. Improved plant protection from external pressures (i.e., insects, weeds, disease, or other environmental stresses).
  2. Improved quality of food products (enhanced vitamin/mineral content, improved taste, increased shelf life).
  3. Development of new products such as industrial compounds and pharmaceutical proteins.

Bio-pharming falls into this third general category.
