| Research Abstract |
Reactive oxygen species (ROS) are molecules that oxidize lipids, protein, and DNA, and create damage to cellular function, in general. However, ROS are essential for living cells as well as plant cells. How do plants utilize toxic ROS? Arabidopsis has ten enzymes, AtRbohA-J, which have ROS-producing activities. We showed that the each AtRboh gene was expressed in various tissues, all AtRboh proteins were activated by Ca^<2+> or phosphorylation, and some of AtRboh protein was regulated by several interacting proteins. These results suggested that plants generated ROS at a suitable timing and tissue to utilize toxic ROS.
