Taqman ribosomal rna control reagents vic probe

Total RNA was extracted from the juice sacs according to the method described by Ma et al. (2022) [43 (link)]. The RNeasy Mini Kit (Qiagen, Germany) was used to clean the extracted total RNA using on-column DNase digestion. The cDNA was synthesized with 2 µg of purified total RNA using a TaqMan Reverse Transcription Regents (Applied Biosystems, USA).
The gene expression was conducted by real-time quantitative PCR according to the method of Ma et al. (2022) [42 (link)]. As an endogenous control, the TaqMan Ribosomal RNA Control Reagents VIC Probe (Applied Biosystems) was used. The real-time PCR was performed using TaqMan Universal PCR Master Mix (Applied Biosystems) on a StepOnePlus™ system (Applied Biosystems). Each reaction contained template cDNA, 900 nM primers, and a 250 nM probe (Table S2). The thermal cycling conditions were 95 °C for 10 min, followed by 40 cycles at 95 °C for 15 s and 60 °C for 1 min. The data obtained from the StepOnePlus™ real-time PCR software (Applied Biosystems) was used to analyze the gene expression. The results were normalized with the results of 18 S ribosomal RNA. The Real-time quantitative RT-PCR was performed in three replicates for each sample.

Total RNA was extracted from the flavedo and juice sacs of Satsuma mandarin at different stages according to the method described by Ikoma et al. [54 (link)]. The total RNA was cleaned up using the RNeasy Mini Kit (Qiagen) with on-column DNase digestion. The reverse transcription (RT) reaction was performed with 2 μg of purified RNA and a random hexamer at 37 °C for 60 min using TaqMan Reverse Transcription Reagents (Applied Biosystems).
TaqMan MGB probes and sets of primers for CitHYb, CitCYP97A, CitCYP97B, and CitCYP97C were designed with the Primer Express software (Additional file 4: Table S2). For the endogenous control, the TaqMan Ribosomal RNA Control Reagents VIC Probe (Applied Biosystems) was used. TaqMan real-time PCR was carried out with the TaqMan Universal PCR Master Mix (Applied Biosystems) using ABI PRISM 7300 (Applied Biosystems) according to the manufacturer’s instructions. Each reaction contained 900 nM of the primers, 250 nM of the TaqMan MGB Probe, and template cDNA. The thermal cycling conditions were 95 °C for 10 min followed by 40 cycles of 95 °C for 15 s and 60 °C for 60 s. The levels of gene expression were analyzed with ABI PRISM 7300 Sequence Detection System Software (Applied Biosystems) and normalized with the results of 18S ribosomal RNA. Real-time quantitative RT-PCR was performed in three replicates for each sample.
