Outline of Final Research Achievements

Plants have evolved endomembrane-mediated strategies in response to pathogen infections and environmental stresses. These strategies have been investigated by focusing on the endomembrane, especially endoplasmic reticulum (ER). We show that A. thaliana has developed a subcellular type of chemical defence, which involves the ER-derived organelles, designated as ER bodies. The ER moves in an actin-myosin-XI-cytoskeleton-dependent manner, which might cause cytoskeleton regulates organ straightening to adjust plant posture.
