Abstract

The ocs-like elements of the bidirectional mas1'2' promoter of Agrobacterium tumefaciens, mas1' and mas2', were analyzed to elucidate their role in the expression conferred by this promoter. Tetramers of the elements were cloned upstream of the beta-glucuronidase-coding region linked to the 35S promoter deleted at -54. Transient expression assays with tobacco (Nicotiana tabacum) and potato (Solanum tuberosum) protoplasts showed that tetramers of the mas1' element had 3- to 8-fold enhancing activity, respectively. Enhancement obtained by tetramers of the mas2' element was higher, suggesting that this element plays a role in the stronger promoter activity from the 2' side. Three cDNA clones with higher homology to the tobacco transcription factor TGA1a were isolated from a potato root expression library. Overexpression of the proteins encoded by these cDNA clones in Escherichia coli and analysis of DNA-binding activity in bacterial extracts showed that all three factors could bind strongly to the mas1' ocs-like element. In contrast, only two of the mas-binding factors exhibited significant binding to the mas2' element. Southern analysis revealed the presence of a small, multigene family encoding the mas-binding factors in potato.

摘要

对根癌土壤杆菌双向mas1'2'启动子的ocs样元件mas1'和mas2'进行了分析，以阐明它们在该启动子赋予的表达中的作用。将这些元件的四聚体克隆到与在-54处缺失的35S启动子相连的β-葡萄糖醛酸酶编码区的上游。用烟草（烟草）和马铃薯（马铃薯）原生质体进行的瞬时表达分析表明，mas1'元件的四聚体分别具有3至8倍的增强活性。mas2'元件的四聚体获得的增强作用更高，表明该元件在来自2'侧的更强启动子活性中起作用。从马铃薯根表达文库中分离出三个与烟草转录因子TGA1a具有更高同源性的cDNA克隆。这些cDNA克隆编码的蛋白质在大肠杆菌中的过表达以及细菌提取物中DNA结合活性的分析表明，所有三个因子都能与mas1'ocs样元件强烈结合。相比之下，只有两个mas结合因子对mas2'元件表现出显著结合。Southern分析揭示了马铃薯中存在一个编码mas结合因子的小多基因家族。
