| Research Abstract |
To elucidate the mechanism of plant cell polarity establishment, subcellular localization analysis of GNOM and VAN3, vesicle transport regulators, and genetic analysis using arabidopsis mutants were performed. Whereas GNOM and VAN3 colocalized at PMs, they showed differential localization intracellularly. Interestingly, GNOM localization at non-endosomal compartments was also observed. Additionally, some mutation that supposed to be involved in cell polarity establishment was identified by next generation sequencing.
