| Outline of Final Research Achievements |
I analyzed the function of the paternal-effect gene SSP1 and maternal-effect gene AtMAGO in apical-basal axis formation of Arabidopsis embryo to uncover the molecular mechanisms of parental effects on plant embryogenesis. I found that AtMAGO is required for the proper polarized-localization of SSP1 in the zygote and that AtMAGO is also involved in SSP1-driven MAPKKK signaling cascade. Besides, RNA-binding protein AtMAGO was localized in the periphery of egg cell with polarity, suggesting apical-basal axis formation in early embryogenesis via polar-localized SSP1 mRNA.
