Abstract

Chloroplast genomes defied the laws of Mendelian inheritance at the dawn of plant genetics, and continue to defy the mainstream approach to biotechnology, leading the field in an environmentally friendly direction. Recent success in engineering the chloroplast genome for resistance to herbicides, insects, disease and drought, and for production of biopharmaceuticals, has opened the door to a new era in biotechnology. The successful engineering of tomato chromoplasts for high-level transgene expression in fruits, coupled to hyper-expression of vaccine antigens, and the use of plant-derived antibiotic-free selectable markers, augur well for oral delivery of edible vaccines and biopharmaceuticals that are currently beyond the reach of those who need them most.

摘要

在植物遗传学诞生之初,叶绿体基因组就违背了孟德尔遗传定律,并且持续挑战生物技术的主流方法,引领该领域朝着环境友好的方向发展。近期,在对叶绿体基因组进行工程改造以实现抗除草剂、抗虫、抗病、抗旱以及生产生物制药方面取得的成功,开启了生物技术的新纪元。成功对番茄有色体进行工程改造,使其在果实中实现高水平转基因表达,并与疫苗抗原的超表达相结合,以及使用植物源无抗生素选择标记,这对于口服递送目前最急需人群难以获得的可食用疫苗和生物制药而言,是个好兆头。
