Methylation level in leaf 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	18.61d	20.74c	4.38b	3.68bc	14.23d	17.06bc
T1	19.66cd	21.24c	3.45bc	2.94c	16.21c	18.30b
T2	21.87c	23.03bc	4.18b	4.42b	17.69bc	18.61b
T3	24.54bc	24.71bc	4.60b	4.65b	19.94ab	20.06ab
T4	26.98b	28.80a	6.81ab	7.73a	20.16ab	21.07a
T5	28.42ab	30.62a	7.49a	8.61a	20.93a	22.01a

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).
