Histone deacetylases and hisone demethylases may therefore play an important role in plant response to abiotic stresses. The protein-protein interaction between the histone decetylase HDA6 and the histone demethylase FLD suggests a functional interplay between histone deacetylase and demethylase in plants. Environmental stresses, such as extremes of temperature, drought, salinity and pathogens, cause significant crop losses on an annual basis. Given the importance of epigenetic mechanisms in regulation of the gene expression in plants, further analysis of how HDMs and HDAs modulate gene expression may have wide application of crop improvement, particularly in the field of environmental stress tolerance.組蛋白去甲基化&#37238植物逆境反應表觀遺傳學histone demethylasesabiotic stressepigenetics
