叶绿体基因工程：一种植物生物技术的新方法

以叶绿体转化为主的叶绿体基因工程,与传统的基因工程技术细胞核转化相比，在外源基因表达水平和转基因植物安全性等方面有明显的优势, 尤其是在控制转基因沉默和遗传稳定性方面，可以互补核转化带来的局限性。因此,叶绿体基因工程是一种很具有发展前景的植物转基因技术,并在未来工农业生物技术领域发挥重要作用。本文着重在叶绿体转化技术主要特点,应用领域及其未来的发展前景等方面进行了简单评述。

Chloroplast Genetic Engineering: A New Approach in Plant Biotechnology

Chloroplast genetic engineering, offers several advantages over nuclear transformation, including high level of gene expression, increased biosafety, remedying some limitations associated with nuclear genetic transformation, such as gene silencing and the stability of transformed genes. It is now regarded as an attractive new transgenic technique and further development of biotechnology in agriculture. In this article we reviewed the characteristics, applications of chloroplast genetic engineering and its promising prospects were discussed.
