    • Synthetic elements for enhancing expression of genes in plant cells are disclosed. These include a promoter with a “TATA to start” sequence containing 64% or greater GC content and an synthetic upstream element incorporating several OCS binding motifs and novel flanking sequences. Upstream activating regions (UARs) are also disclosed that can further increase the constitutive transcriptional activity when they are operably linked to said promoter and/or the synthetic upstream element. In particular, the nucleotide sequence of the UAR of the maize Ubi-1 gene is provided and its use in expression cassettes and vectors containing these promoter elements. Cells and plants transformed with these vectors are further provided. These include a transgenic sunflower expressing an exogenous oxalate oxidase gene at a high level under the transcriptional control of a recombinant promoter having at least one upstream activating region of the 35S CaMV promoter.
    • 公开了用于增强植物细胞中基因表达的合成元件。 这些包括具有含有64%或更高GC含量的“TATA起始”序列的启动子和包含若干OCS结合基序和新侧翼序列的合成上游元件。 还公开了上游活化区(UAR),当它们可操作地连接到所述启动子和/或合成上游元件时,可以进一步增加组成型转录活性。 特别地,提供了玉米Ubi-1基因的UAR的核苷酸序列,并且其用于表达盒和含有这些启动子元件的载体。 进一步提供用这些载体转化的细胞和植物。 这些包括在具有35S CaMV启动子的至少一个上游活化区的重组启动子的转录控制下在高水平表达外源性草酸氧化酶基因的转基因向日葵。
