Outline of Final Research Achievements

1, In rice, arabinose side chain and adjustment of methylation of pectin are important for the formation of pollen cell wall and mechanical guidance of pollen tube in pistil. In abscission zone at the time of organ detachment, characteristic cell wall rearrangement occurs.
2, In tissue reunion of cut flowering stem of Arabidopsis, XTH 20 etc. is involved in pith cell division downstream of auxin and transcription factors. Iron transporter, CLE6 peptide, xylem sap proteins and sugars regulated by shoot gibberellin, short day and low temperature are involved in shoot development.
3, The sugar chain of arabinogalactan protein is essential for cell morphology and differentiation.
