Histone epigenetic modification of the TIFY10A and LBD37 genes in the two populations. a. Alignment of the nucleotide sequences of the coding region of the TIFY 10A and LBD37 genes in the HK and JN populations. Asterisks indicate the same nucleotide in these two populations. b. ChIP assay of the relative levels of H3K9ac and H3K4me3 in TIFY10A and LBD37 chromatins of the HK and JN plants before cold treatment. The primer used in the PCR is shown as bars below the genes. Data are the means±SD of triplicate experiments. Bars with different letters are significantly different at P < 0.05 (ANOVA followed by Tukey’s post-hoc test)
