Plant synthetic biology: from inspiration to augmentation

Although it is still in its infancy, synthetic biology has the capacity to face scientific and societal problems related to modern agriculture. Innovations in cloning toolkits and genetic parts allow increased precision over gene expression in planta. We review the vast spectrum of available technologies providing a practical list of toolkits that take advantage of combinatorial power to introduce/alter metabolic pathways. We highlight that rational design is inspired by deep knowledge of natural and biochemical mechanisms. Finally, we provide several examples in which modern technologies have been applied to address these critical topics. Future applications in plants include not only pathway modifications but also prospects of augmenting plant anatomical features and developmental processes.
