| Outline of Final Research Achievements |
The Arabidopsis transcription factor GL2 acts most downstream in a transcriptional network that is implicated commonly in plant epidermal cell differentiation. We tried to elucidate regulatory roles of further downstream factors from GL2 in root hair cell differentiation. As the result, the lipid metabolizing enzyme PLDζ1, the gene of which is a GL2 direct target, localized to trans-Golgi network in a manner dependent of its N-terminal region. In addition, the transcription factor LRL1, the gene of which is also a GL2 direct target, recognizes genes encoding regulatory factors of Rho GTPase. These suggest that various intracellular signaling systems function further downstream from GL2 for root hair cell differentiation.
