summary RNA core promoters are nucleotide sequences needed to direct proper initiation of viral RNA synthesis by the viral replicase. Minimal length core promoter-templates that can direct accurate initiation of the genomic plus-, genomic minus-, and subgenomic RNAs of Brome mosaic virus and Cucumber mosaic virus were characterized in previous works. Several common themes and differences were observed in how each of the core promoters directed the initiation of viral RNA synthesis in vitro. These observations are summarized and compared in this short review.
摘要 RNA 核心启动子是指导病毒复制酶正确启动病毒 RNA 合成所需的核苷酸序列。在之前的研究中，已经对能够准确启动 Brome mosaic virus 和 Cucumber mosaic virus 的基因组正链、基因组负链和亚基因组 RNA 的最小长度核心启动子模板进行了描述。在体外，每个核心启动子指导病毒 RNA 合成的起始过程中，观察到了一些共同的主题和差异。本文对这些观察结果进行了总结和比较。
