Total RNA was extracted from rice tissues using an RNA Extraction Kit (Macrogen, South Korea) according to manufacturer instructions. First-strand cDNA was synthesized with 2 µg of total RNA in a 25 µl volume using M-MLV reverse transcriptase and oligo(dT)15 primer (Promega), and diluted with 75 µl of water. The qPCR amplifications were conducted on the LightCycler 2.0 instrument (Roche Diagnostics). The 20 µl of qPCR mixture included 2 µl of the first-strand cDNA mixture, 10 µl of 2X GoTaq PCR Master Mix (Promega), and 1 µl of 10 pM primer pairs (Supplementary Table S1). The qPCR conditions were 95°C for 2 min, followed by 50 cycles at 95°C for 5 s, 59°C for 15 s, and 72°C for 10 s. The rice UBIQUITIN5 (OsUBQ5, AK061988) gene was used as an internal control for normalization. The semi-quantitative PCR was performed in a 20 µl volume containing 2 µl diluted cDNA, 1 unit Ex Taq polymerase (TaKaRa Biotechniques), and 1 µl of 10 pM primers (listed in Supplementary Table S1). The PCR program included initial denaturation at 94°C for 3 min, followed by specified cycles at 94°C for 30 sec, 55°C for 1 min, and 72°C for 40 sec, followed by a final extension at 72°C for 5 min. The PCR products were electrophoresed on a 1% agarose gel. OsUBQ5 was used as an equal loading control.

Quantitative RT-PCR Analysis of Rice Transcripts

For the RT reactions, total RNA was extracted from rice leaf blades and other tissues using an RNA Extraction Kit (Macrogen, Korea). First-strand cDNA was prepared with 2 μg total RNA using M-MLV reverse transcriptase and oligo(dT)15 primer (Promega) in a total volume of 25 μl and diluted with 75 μl water. For quantitative reverse-transcription PCR (qPCR), a 20 ml mixture was prepared including first-strand cDNA equivalent to 2 μl total RNA, 10 μl 2× GoTaq master mix (Promega), 6 μl distilled water, and gene-specific forward and reverse primers (Supplementary Table 1). The qPCR was performed using a LightCycler 480 (Roche Diagnostics). Rice Ubiquitin5 (UBQ5) or GAPDH (encoding glyceraldehyde phosphate dehydrogenase) was used as an internal control. The relative expression level of each gene was calculated using the 2−ΔΔCT method, as previously described (Livak and Schmittgen, 2001 (link)).

For the reverse transcription reactions, total RNA was extracted from rice leaf blades and other tissues using an RNA Extraction Kit (Macrogen, Seoul, Korea). First-strand cDNA was prepared with 2 μg total RNA using M-MLV reverse transcriptase and oligo(dT)15 primers (Promega) in a total volume of 25 μl and diluted with 75 μl water. For quantitative PCR (qPCR), a 20 μl mixture was prepared including first-strand cDNA equivalent to 2 μl total RNA, 10 μl 2×GoTaq master mix (Promega), 6 μl distilled water, and gene-specific forward and reverse primers (Supplementary Table S1).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
