Due to an increase in public concern about radiation after the Fukushima nuclearaccident, an array of studies have been executed to understand the biological effects of radiationusing model organisms such as Arabidopsis rather than humans. Although a large amount ofinformation about the biological effect of radiation has been accumulated, most of the studieswere performed at the transcriptional level. To systematically understand the biological effects ofradiation, here, we performed proteome analysis using A. thaliana in the two vegetative stages [early(10-day-old) and late (21-day-old) vegetative stages] and identified radiation-responsive proteins. This analysis revealed that the proteins involved in the oxidative stress, molecular chaperone,and general stress responses showed an abundant change post γ-radiation exposure. Notably, weidentified four proteins (acryl carrier protein 4, glycine cleavage system H protein 1, peptidylprolylcis-trans isomerase CYP20-3, and calreticulin-1) that showed protein expression changes inboth early and late vegetative stages after γ-radiation exposure. Furthermore, the Gene Ontology(GO) analysis revealed that proteins changed post γ-radiation exposure were mainly involved inprotein binding activities and responses to stress. Collectively, we reported that proteins involvedin oxidative stress and molecular chaperones showed an abundant change in response to radiationexposure in the vegetative stage of the A. thaliana.
