Elucidation of the mechanism of stress tolerance via lipid droplets in plants
Lipid droplets are the organelle to store neutral lipids. Plant seeds have a lot of lipid droplets for energy source of germination. On the other hand, leaves also have lipid droplets; however, the functions of leaf-lipid droplets are poorly known.
We found that leaf-lipid droplets were induced and formed during various stress conditions. Additionally, we also found that there were various proteins on leaf-lipid droplets. In this study, we try to resolve the molecular mechanisms and physiological functions of leaf-lipid droplets; do the leaf-lipid droplets and their proteins contribute to plant stress tolerance?


I have been studying plant oil droplets since I was a student. It has been suggested that plant oil droplets have a variety of roles beyond energy storage, but this has yet to be proven. Through this research, I will try to unravel some of the functions of oil droplets.

Outline of Research Achievments

To clarify the physiological functions of plant lipid droplets, we analyzed lipid-droplet-localized proteins. We also analyzed stress tolerance using an Arabidopsis mutant that excessively accumulates lipid droplets on the leaves. We discovered myosin-binding proteins (MYOBs) as lipid-droplet-localized proteins, and published our findings in a paper.
