SAHA treatment enhanced H3K14ac levels at promoters of flavonoid biosynthesis genes. A Schematic diagram illustrating primer locations for ChIP-qPCR. H3K14ac level detection at GiIFS (Gi1.9955) (B), GiCYP73A (Gi2.1616) (C), GiPAL (Gi3.125) (D), GiPAL (Gi5.1238) (E) and GiCHS (Gi5.966) (F) loci in 7-day-old G. inflata seedlings treated with SAHA or DMSO (control) for 6 h and 24 h, as determined by ChIP‐qPCR assay. Values represent means ± SD. Student’s t-test, *P < 0.05, ** P < 0.01, *** P < 0.001, n ≥ 3
