Methylation level in root of wheat seedlings determined by MSAP.

	Methylation level (%)		Hemi-methylation level (%)		Full-methylation level (%)
	Wheat XM13	Wheat AK58	Wheat XM13	Wheat AK58	Wheat XM13	Wheat AK58
CK	28.95c	26.17d	5.85c	7.79b	23.10a	18.38c
T1	26.84cd	27.13cd	6.78bc	6.31bc	20.06b	20.82b
T2	27.58bc	28.61bc	7.69b	7.22b	19.89b	21.39ab
T3	27.96bc	29.25bc	8.06ab	7.24b	19.90b	22.01a
T4	31.10ab	31.19b	8.61a	7.62b	22.49a	23.57a
T5	33.11a	33.85a	9.24a	10.24a	23.87a	23.61a

CK, T1, T2, T3, T4 and T5 represented wheat seedlings under different osmotic potentials of PEG₆₀₀₀ solution with 0.00, −0.05, −0.15, −0.30, −0.50 or −0.75 MPa, respectively. The different lowercase letters in the same column denoted the significant difference among treatments of two wheat cultivars (P < 0.05).
