诱导型启动子在植物基因工程中的研究进展

摘要

Inducible promoters can not only make the expression products of target genes at a specific time,and avoid unnecessary waste of plant energy,but also prevent toxic effects caused by over expression of genes and crop yield decline or even death happening.In this paper,the latest research progress of inducible promoters in plant genetic engineering was reviewed to understand the regulation mechanism of gene expression in higher plants and apply inducible promoters in crop improvement with plant genetic engineering.%诱导型启动子不仅能使目的基因的表达产物在特定时期积累,避免植物能量的不必要浪费,而且可以避免基因过表达对植物造成的毒害,以及因此造成的植物减产甚至死亡.综述了高等植物诱导型启动子在植物基因工程中的最新研究进展,以期使人们更加深入地了解高等植物基因表达调控机制,为植物基因工程及作物改良研究提供具有应用价值的启动子元件.
