 This finding is significant as it provides an alternative pathway for generation of transplastomic plants for species that are not as easily transformed using our current experimental methodology as seen above.Inducible expression systems such as theoriboswitches and pentatricopeptide repeat proteins have been widely studied in an effort to control and modulate expression of transgene products in transplastomic plants.One big advantage in using inducible expression systems is to optimize concentration of transgene protein production.
