We investigated the mechanism of gene expression in plant seeds induced by low-pressure oxygen radio frequency plasma irradiation using microarray analysis and quantification of DNA methylation. A decrease in the amount of gene expression of AT2G30620 indicated that the chromatin structure is modified by active oxygen species generated in oxygen plasma. The increase in the DNA methylation level in plant seeds was determined by using a DNA methylation quantification method. Gene expression in plant seeds induced by active oxygen species was influenced by the epigenetic variation of DNA methylation and chromatin structure.
