The simplest structure phytohormone ethylene (C₂H₄) regulates the important aspect of plant growth and development throughout its life cycle. So far, no systemic studies were performed to determine the ethylene effect on seed germination-associated epigenetic phenomenon. Henceforth, a laboratory investigation was performed to explore the epigenetic impact of ethephon (ET) priming on soybean [Glycine max (L.) Merrill] germination. Our findings demonstrated that ET (250 ppm) induced soybean germination significantly: (1) altered the chromatin architecture; (2) reduced the global DNA methylation and 5-methylcytosine levels; (3) reduced the DNA methyltransferases (DNMTs) activity; (4) decreased and increased the transcript levels of DNA methylases (viz. GmMET1, GmDRM1 and GmCMT3) and demethylase (viz. GmROS1), respectively; and (5) enhanced the endogenous levels of DNMT inhibitor, genistein. Based on these observations, a novel epigenetic impact of ethylene in seed germination process has been proposed.
