Figure 4: qRT-PCR analysis of the expression level of PhANGs and PEGs.

About 0.1 g 12-day-old plants grown under normal condition were used for RNA extraction. First-strand cDNA was synthesized from 1 μg total RNA with Oligo dT primer for qRT-PCR analysis. Relative transcription levels of the genes in ATHB17 OX and KO are normalized to levels in WT control (WT = 0). Values are mean ± SD of three independent experiments.
