中文摘要：
以入侵植物紫茎泽兰（Ageratina adenophora Sprengel）为材料，采用基于PCR方法的染色体步行和改良的热不对称交错PCR（thermal asymmetric interlaced PCR，TAIL-PCR）两种方法分别克隆到hsp90和hsp17.66基因的5′上游启动子序列，长度分别为864bp和1485bp（GenBank登录号分别为FJ434253和FJ434252）。测序结果表明：这两个启动子序列均具有hsp启动子特有的HSE元件，及其他一些启动子顺式作用元件，如TATA-box，CAAT-box等。
英文摘要：
The promoter region of hsp90 with 864 bp （GenBank No. FJ434253）, from invasive weed Ageratina adenophora was amplified based on PCR methods, which are available as chromosome walking from a known sequence to an unknown region. Moreover, another promoter region of hsp17.66 with 1 485 bp （GenBank No. FJ434252） was cloned by thermal asymmetric interlaced PCR （TAIL-PCR）. Both of the 5＇-flanking regions of hsp90 and hsp17.66 contained specific HSE element and several cis-acting elements, such as TATA-box, CAAT-box,et al.
