Drought-induced gene alteration is usually associated with changes of histone H3K4me3 in plants. Histone methylation homeostasis relies on the coordinated activity of methyltransferases and demethylases. We previously demonstrated that SsJMJ11 is an H3K4me3 demethylase in Saccharum spontaneum and pa...
