Evaluation of Reference Genes for Normalizing RT-qPCR and Analysis of the Expression Patterns of WRKY1 Transcription Factor and Rhynchophylline Biosynthesis-Related Genes in Uncaria rhynchophylla

Detian Mu,
Yingying Shao,
Jialong He
et al.

Abstract: Uncaria rhynchophylla (Miq.) Miq. ex Havil, a traditional medicinal herb, is enriched with several pharmacologically active terpenoid indole alkaloids (TIAs). At present, no method has been reported that can comprehensively select and evaluate the appropriate reference genes for gene expression analysis, especially the transcription factors and key enzyme genes involved in the biosynthesis pathway of TIAs in U. rhynchophylla. Reverse transcription quantitative PCR (RT-qPCR) is currently the most common method … Show more

“…The total RNAs from U. rhynchophylla leaves were isolated according to the manufacturer’s instructions via the SteadyPure Plant RNA Extraction Kit (Accurate Biology, Hunan, China). The primers used for qRT-PCR Specific primer pairs designed using Beacon Designer 7.0 software are listed in Supplementary Table S3 ; the primers of key enzyme genes involved in TIA biosynthesis pathway have been reported previously with the SAM gene as the internal reference gene [ 62 ]. The qRT-PCR was performed using 2× SYBR Green Pro Taq HS premix (Vazyme, Shanghai, China) and reaction system and procedure have been previously reported [ 63 ], using the following protocol: 95 °C for 3.00 min, 1 cycle; 95 °C for 15 s and 60 °C for 30 s, 40 cycles.…”
