Gene Expression Effect of Plant Seeds Irradiated by Low Pressure Oxygen Plasma

Abstract

Effect of gene expression in plant seeds irradiated by low-pressure oxygen plasma has been investigated using microarray analysis and quantification of DNA methylation. The active oxygen species generated in oxygen plasma acted plant seeds, and increased the DNA methylation level of plant seeds determined using DNA methylation quantification method. This indicated that gene expression in plant seeds induced by active oxygen species was owing to epigenetic variation of DNA methylation.
