title: The analysis of proteome changes in sunflower seeds induced by N+ implantation.
abstract: In this work, the proteomic changes induced by N+ ion implantation were investigated using a sunflower seed model by a two-dimensional electrophoretic analysis. To further understand the changes of total protein irradiated with N+ ion, a proteomic analysis of N+ ion implantation seeds was developed. Among approximately 369 total protein spots displayed in 2-D gels, eight specific proteins were found in non-implanted seeds while four proteins were found in implanted seeds. Six proteins were used for MALDI-TOF MS analysis, of which only two had been reported before. The proteins designated as No.29 showed 23.4% homology to MADS-box transcriptional factor HAM59, while No. 279 protein had 23.20% identity to homeobox-leucine zipper protein HAHB-4. The analysis of proteome changes induced by N+ implantation could provide a new clue to studying mutation mechanism of ion implantation. To our knowledge, this is the first report about the analysis of proteome changes induced by N+ implantation in sunflower seeds.
