摘要/Abstract

摘要： 实时荧光定量PCR已广泛用于基因表达的分析, 适当的内参基因选择是获得准确分析结果的关键。在大豆(Glycine max)分子生物学研究中, 逆境响应基因和microRNA (miRNA)表达的内参辅助检测基因均有哪些目前尚不清楚。该研究选用不同盐梯度和时间点组合处理的大豆根组织为材料, 对已报道的其它条件下表达相对稳定的内参基因(ACT、ACT2/7、CYP2、ELF1A、ELF1B、F-Box、TUA和UBC2)以及miRNA内参基因(U6、miR1515a、miR1520c、miR1520d、miR171a和miR171b)的表达情况进行了全面检测; 并采用Δ-Ct、Bestkeeper、NormFinder和Genorm四种方法对检测结果进行了综合分析, 发现ELF1B和CYP2适合作为大豆根系盐胁迫响应基因研究的内参基因, miR1515a和U6适合作为盐胁迫下大豆根组织miRNA研究的内参。上述研究结果为大豆盐胁迫响应基因和miRNA表达及其进一步的功能研究奠定了基础。

Abstract: Quantitative RT-PCR (qRT-PCR) is a robust and commonly used technique to study gene expression. However, the reference genes and microRNA (miRNA) that can be used in soybean molecular research, in particular the stress responsive genes and miRNA in roots, are not well characterized. In this study, we systematically analyzed the expression stability of eight widely used reference genes (ACT, ACT2/7, CYP2, ELF1A, ELF1B, F-Box, TUA and UBC2) and miRNA internal references (U6, miR1515a, miR1520c, miR1520d, miR171a, and miR171b) in root tissues treated with different NaCl concentrations at specified times. The Δ-Ct method, Bestkeeper 1.0, NormFinder 0.953 and Genorm 3.5 were used to analyze the data, then the web-based tool RefFinder was used to integrate the results obtained. ELF1B/CYP2 and miR1515a/U6 were the most suitable genes for qRT-PCR analysis of soybean gene and miRNA expression analysis under salt stress, respectively. The highly ranked reference genes and miRNAs identified from this study can be used for detecting differences in expression rates of genes and miRNAs in response to salt stress in soybean.
