| Research Abstract |
We obtained following results about the action of lipid peroxide-derived reactive aldehydes (RAL) in plant responses to environmental stress:
(1) The RAL species responsible for the aluminum-induced oxidative injury in roots and those for the strong-light-induced photooxidative injury in leaves identified.
(2) Light-dependent formation of organic peroxides on the donor side of photosystem II that lacked the water-oxidizing complex was proven.
(3) In NaCl-stressed plants, modification of proteins with RAL were increased. The modified targets were identified.
(4) The target amino acid(s) in phosphoribulokinase that have primary importance in the sensitivity to acrolein was not the redox-regulated Cys.
