| Outline of Final Research Achievements |
In this study, we proposed that charophyte algae, which are the closest algae to land plants, acquired a cuticle-like hydrophobic layer composed of triacylglycerol to adapt to a terrestrial environment by initial land colonization. To demonstrate the hypothesis, we analyzed surface lipids and transcriptome of Klebsormidium, which early diverged from charophyte algae ancestor. As a result, it is assumed that surface structure and its related gene regulation were evolved in a stepwise manner during land colonization while using triacylglycerol as hydrophobic barrier. These results will provide information to clarify relation between process of land colonization by plants and evolution of its surface lipid.
