66044Chloroplast Transformation, a Safe and Environmentally Friendly Approach for Production of Transgenic Plant

C hloroplast genetic engineering offers a number of unique advantages as compared with nuclear transformation, including a high-level transgene expression, multi-gene engineering in a single transformation event, lack of gene silencing, position and pleiotropic effects, and undesirable foreign DNA. Furthermore transgene containment is an important advantage that introduces chloroplast transformation as a safe and environmentally friendly approach. Plastid engineering significantly increases the containment of transgenes because plastids are maternally inherited in most crops and are therefore not spread through pollen from transplastomic plant to another nontransgenic and wild type species that is important for purposes of biosafety. This article provides a reviewes on plastid transformation techniques
