巴西橡胶树HbSERK1启动子的克隆及功能鉴定
Molecular and Functional Characterization of the HbSERK1 Promoter in Hevea brasiliensis
摘要
Abstract
The 5'regulatory region of HbSERK1 from Hevea brasiliensis was cloned using GenomeWalker strategy.A/T content in this sequence is up to 66.2%,and meet the characteristic of eukaryotic promoter sequence.TATA box,CAAT box CAT-box,02-site,ERE,ARE,TCA-element,GCN4-motif,ACA-motif were found in this promoter region.In order to verify HbSERK1 promoter function,Five deletions plant expression vector were constructed and transformed to the tobacco by Agrobacterium-mediated vacuum infiltration method and Agrobacterium-mediated.GUS activity analysis revealed that the region from-1 395~-252 bp nt drived expression of the GUS gene except SP5 deletion (-252 bp).The results of transient expression and stable expression suggest HbSERK1 promoter possess bioactivity.关键词
