| Research Abstract |
Endoplasmic reticulum (ER) body is an ER derived structure that is accumulated in Arabidopsis thaliana. ER body is involved in plant defense system against insect and pathogen attack, since wound treatment induced ER bodies. Two soluble proteins NAI2 and PYK10, and two integral membrane proteins MEB1 and MEB2 are accumulated specifically in ER bodies, but their functions were obscure. I found that NAI2 and PYK10 are responsible for the ER body formation. MEB1 and MEB2 have iron/manganese transport activity, suggesting that ER body is involved in the metal stress resistance. These findings unrevealed unique mechanisms for ER body formation and function in plants
