    Selection and validation of reference genes for quantitative real-time PCR during the developmental stages of seeds in Sophora davidii by Jingjing Li, Jingjing Li, Shanrong Han, Shanrong Han, Zongren Xu, Bin Deng, Na Zheng, Na Zheng, Yaqiong Su, Yaqiong Su, Ziyao Qiao, Ziyao Qiao, Yun Yang, Yun Yang, Hong Zhang, Zongsuo Liang, Jing Liu, Shuai Liu

    Published 2025-05-01
    “…However, the biosynthetic pathway of these alkaloids remains incompletely elucidated, and the expression patterns of key enzyme genes involved in this pathway require further investigation. Quantitative real-time PCR (qRT-PCR) serves as a highly sensitive method for gene expression analysis, yet selecting appropriate reference genes is crucial to ensure the accuracy and reliability of results.MethodsTen candidate reference genes (18S, ACT13, RL15B, RL74, RLA2, RL182, RL291, EF1-α, EF1G, and YLS8) were evaluated for their expression stability in Sophora davidii seeds collected at five distinct developmental stages post-flowering, characterized by significant morphological changes. …”
