一种β-葡萄糖苷酶基因启动子及其应用
摘要：
本发明公开了一种β-葡萄糖苷酶基因启动子及其应用。该启动子具有下述核苷酸序列：序列表中SEQ ID NO：1或在高严谨条件下可与序列表中SEQ ID NO：1限定的DNA序列杂交的核苷酸序列。本发明的β-葡萄糖苷酶基因启动子可启动报告基因gusA在植物的幼苗和小苗根系中特异性高效表达，表达水平高于双子叶植物基因工程中常用的CaMV35S启动子。该启动子可用于植物基因工程，特别是用于在植物幼苗和小苗根系中表达特定的目的基因。
摘要（英）：

The present invention discloses one kind of beta-glucosaccharase gene promoter and its application. The promoter has the nucleotide sequence as shown in SEQ ID No. 1 of the sequence list, or the nucleotide sequence capable of hybridizing with the DNA sequence defined by SEQ ID No. 1 of the sequence list under high strict condition. The beta-glucosaccharase gene promoter of the present invention can initiate reporter gene gusA for expressing in plant seedling root system specifically and effectively, with the expression level being higher than CaMV35S promoter commonly used in dicotyledon geneengineering. The beta-glucosaccharase gene promoter may be applied in plant gene engineering, especially for expressing specific target gene in plant seedling root system.
