Plants and plant tissue cultures are used as host systems for expression of foreign proteins including antibodies, vaccines and other therapeutic agents Recombinant or stably transformed plants and plant cell cultures have been applied for foreign protein production for about 20 years. Because the product concentration achieved exerts a major influence on process economics, considerable efforts have been made by commercial and academic research groups to improve foreign protein expression levels However. post-synthesis product losses due to protease activity Within plant tissues and/or extracellular protein adsorption in plant cell cultures can negate the benefit,; of molecular or genetic enhancement of protein expression Transient. expression of foreign proteins using plant viral vectors is also a practical approach for producing foreign proteins in plants. Adaptation of this technology is required to allow infection and propagation of engineered Viruses in plant tissue cultures for transient protein expression in vitro (C) 2009 Elsevier Inc.
