Research Abstract

Endoplasmic reticulum (ER) body is an ER derived structure that is found in the epidermal cells of Arabidopsis seedlings. ER body is involved in plant defense system against insect and pathogen attack, since wound treatment induced ER bodies. Two ER body proteins, NAI2 and PYK10 are involved in ER body formation, but its function was obscure. To understand the ER body formation in detail, I analyzed ER body proteins in Arabidopsis. I found that two ER body proteins, MEB1 and MEB2 are localized specifically in ER body membrane. Furthermore, I found that NAI2 and PYK10 are necessary and sufficient for the ER body formation. These findings unrevealed unique mechanisms for ER body formation in plants.
