Ethionine activity assay. (A) Ethionine altered the growth status of apple calli. Apple calli transfected with empty vector (1); MdFERL6-AS (2); and MdFERL6-OE (3). (B) Measurement of calli weight. Transfected apple calli were weighed before treatment (0 day, and were then cultivated with ethionine for 7 days. The increase in weight between 0 and 7 days is indicated on the y-axis. Values are means + SD of three biological replicates. Single asterisks denote a significant difference at P < 0.05 using Student's t-test; double asterisks denote a significant difference at P < 0.01 using Student's t-test. (C) Gene expression of MdFERL6 and MdSAMS were detected in apple calli cultivated in 200 μM ethionine for 7 days. Values are means + SD of three biological replicates. Single asterisks denote a significant difference at P < 0.05 using Student's t-test; double asterisks denote a significant difference at P < 0.01 using Student's t-test.
