To extract RNA from shoots and roots, 3 weeks old control and treated plants were harvested at 2pm in the greenhouse. Total RNA was extracted using the AccuPrep® Universal RNA extraction kit (Bioneer, Daejeon, Korea) and treated with RNase-free DNase to remove DNA fragments (Qiagen, Hilden, Germany). One microgram of total RNA was used to synthesize cDNA with AccuPower® RT PreMix (Bioneer, Daejeon, Korea). Quantitative real-time RT-PCR was conducted using a T100TM Thermocycler system (Bio-Rad, Hercules, CA, USA). Primer information is given in Table S7. Reactions (10 µL final volume) were prepared using 5 µL of LaboPass™ SYBR Green Q Master Kit (Cosmogenetech, Dajeon, Korea). 0.5 pmol of a primer pair, and 0.5 µL of cDNA template. 4 biological samples and two technical replicates were used for the quantifications. Ubiquitin was used as the reference. gene expression analysis was performed with the 2^−ΔΔCt method using Bio-Rad CFX Maestro software v.4.0 (Bio-Rad). Baseline and threshold levels were set according to the manufacturer’s instructions. Overall design: qPCR gene expression profiling. Soot and root samples were acquired and cDNA synthezised using 1microgram RNA. qPCR was conducted using CYBR green with Biorad C-1000. Less...
