| Research Abstract |
To identify the phosphorylation signal network in plant immunity, we performed screening of T-DNA insertion lines in Arabidopsis to determine proteins with changed phosphorylation status in response to MAMP treatment as indicated by measurement of reactive oxygen species (ROS) by flg22 treatment. We identified 38 genes that showed abnormal ROS production after flg22 treatment. Additionally, some candidates exhibited the abnormal immune responses against bacterial pathogen infection, suggesting that phosphoproteomic approaches have the potential to identify novel immune signaling components in plants.
