植物转基因技术(gene transfer)也称遗传转化技术(genetic transformation),是植物基因工程的一个重要组成部分;它通常是指将依据人们一定的需要已经分离、克隆并组建成一定载体形式的外源基因,借助于物理、化学或生物的手段,转入受体植物细胞,实现在新背景下(如细胞、组织、整株水平)表达和遗传的过程。它不仅为基因的表达调控和遗传的研究提供了一个理想的实验体系,更重要的是为植物,尤其是农作物的定向改良和分子育种提供了一个有效的途 Plant gene transfer, also known as genetic transformation, is an important part of genetic engineering of plants. It usually refers to a plant that has been isolated, cloned and assembled into a vector based on human needs Gene, by means of physical, chemical or biological, into the recipient plant cells, to achieve the new context (such as cells, tissues, whole plant level) expression and genetic process. It not only provides an ideal experimental system for the regulation of gene expression and genetics, but more importantly, it provides an effective way for directional improvement and molecular breeding of plants, especially crops.
