Correlation between the number of AtICE1 methylated sites and the extreme minimum temperature, coldest month’s average temperature, coldest season’s average temperature and LT50 values. Correlation between the number of methylated sites in the AtICE1 promoter region (A), CG methylation sites in the AtICE1 gene coding region (B), CHH methylation sites in the AtICE1 gene coding region (C) and CHG methylation sites in the AtICE1 gene coding region (D) and other factors.
