摘要
高等植物中基因表达的调控一直是科学家们最感兴趣的问题之一,也是近年来研究的热点。随着植物基因工程技术的发展和完善,人们对这一问题有了一定程度的了解,发现大多数基因的调控部位都在上游的启动子区域。目前对基因调控的研究主要集中在光调控基因、组织特异性基因、环境胁迫诱导基因及激素诱导基因等几大方面。本文将对以上各个方面的研究成果进行较全面的综述。
The study on regulation of gene expression in higher plants has attracted attention of many scientists and is also one of the major scientific research areas in modern biological studies With advancement of the technology of genetic engineering, more and more details of gene regulation are revealed and it has been found that regulatory zones of most genes are located at the 5 upstream promoter regions. Now, the study on regulation of gene expression is mainlv focused on light regulated genes, tissue specific genes, environmental stress induced genes, hor- mone-induced genes and so on. This article gives a more or less comprehensive review on the several aspects mentioned above.
