The roots of 3-week-old hydroponically cultured Col-0 and sic1 plants were used to extract total RNA by using TRNzol A+ RNA Purification reagent (DP421; Tiangen Biotech, Beijing, China). Two micrograms of total RNA were used to synthesize first-strand cDNA with TransScript one-step gDNA removal and cDNA synthesis super mix (AT311-02; TransGen Biotech, Beijing, China). qRT-PCR was performed using SYBR green PCR master mix (TRT-101; TOYOBO) with the first-strand cDNA as a template on a real-time PCR system (CFX thermocycler; Bio-Rad, ‎Hercules, CA). Primers for qRT-PCR were designed using Primer Express software version 3.0 (Applied Biosystems, Foster City, CA). The primers UBCF and UBCR were designed for ubiquitin-conjugating enzyme 21 (At5g25760), which was used as the reference gene. The primer sequences are shown in S8 Table. Expression data analysis was performed as previously described [51 (link)].

Total RNA was extracted from plants using TRNzol A+ RNA Purification reagent (TIANGEN, DP421, Beijing, China). Two micrograms of total RNA were used to synthesize first-strand cDNA with TransScript One-Step gDNA Removal and cDNA Synthesis SuperMix (Transgen, AT311-02, Beijing, China). qRT-PCR was performed using SYBR Green PCR Master Mix (TRT-101, TOYOBO, Osaka, Japan) with the first-strand cDNA as a template on a Real-Time PCR System (Bio-Rad CFX thermocycler, California, USA). Primers for qRT-PCR were designed using Primer Express Software Version 3.0 (Applied Biosystems, USA). The primers HKT1 exon2-3-1L and HKT1 exon2-3-1R were designed to span an exon-exon junction and were used to detect the gene expression level. The primers UBCF and UBCR were designed for UBIQUITIN-CONJUGATING ENZYME21 (At5g25760), which was used as the control gene. The primer sequences are shown in S3 Table. Expression data analysis was performed as described previously [34 (link)].

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.
