报告摘要:The genomes of plastids (chloroplasts) and mitochondria represent attractive targets of genetic engineering in crop plants. Plastid transgenes often give very high expression levels, can be conveniently stacked in synthetic operons, and are largely excluded from pollen transmission, thus providing increased biosafety of transgenic crops. Recent research has greatly expanded our toolbox for plastid genome engineering, and a number of proof-of-principle applications have highlighted the enormous potential of the transplastomic technology in crop improvement and for the use of plants as bioreactors for the sustainable and cost-effective production of biopharmaceuticals, enzymes and raw materials for the chemical industry. While a technology for transgene insertion into mitochondrial genomes is not yet available, the recent development of genome editing methods for mitochondria has enabled the targeted manipulation of endogenous mitochondrial genes. In my talk, I will (i) describe the state of the art in chloroplast genome engineering, (ii) highlight selected applications of plastid transformation in biotechnology and synthetic biology, and (iii) discuss recent advances with engineering the mitochondrial genomes of plants.
