The populational signals derived from bacteria can induce plant resistance to pathogen or regulate plant development. Here we used 2D proteomics method to investigate Arabidopsis thaliana seedlings responding to OHHL, one of bacterial popular signals. After 2D proteomics and assay, we obtained 47 differential protein spots, most of their expression show increase with the extension of treatment time; these proteins are also involved in plant antioxidant activity, material metabolism and signal transaction. Therefore, we believe our results will show more insight into understanding the interactions mechanism of plant and microbe, and further well regulate plant themselves growth and development.
