分析植物应答环境因子的一种有效平台--DNA微阵列

随着植物基因组测序工程的迅速发展，大量的DNA序列不断地快速对外公布。如何把这庞大的核苷酸序列信息与植物的生命活动有机地联系起来?高通量的DNA微阵列技术是连接植物基因组序列信息和植物功能基因组的桥梁；而且，这一技术在分析基因表达谱和基因的功能上已经得到了应用。通过简要叙述DNA微阵列技术的几个特点，着重分析近几年来该技术在研究植物对环境胁迫的响应机制以及环境信号间相互作用方面的应用。

An Effective Approach to Assay Plant Response to Environmental Factors--DNA Microarray

With huge plant DNA data released by genome sequence project,the high-throughput DNA microarray technology has been proven an effective way to bridge the gap between plant genome sequence information and functional genomics.The technology has been used to investigate the gene expression patterns and to elucidate the role of genes.In this review,we briefly outline the features of DNA microarray and highlight its recent applications in plant biology,especially in the identification of stress-response elements and in the clarification of plant signal network.
