Annotated Information

Gene Symbol

  • Os01g0110200 <=> OsAGP12


  • Arabinogalactan proteins is an umbrella term applied to a highly diverse class of cell surface glycoproteins, many of which contain glycosylphosphatidylinositol lipid anchors.[1] [2]
  • Arabinogalactan proteins (AGPs) comprise a family of hydroxyproline-rich glycoproteins that are implicated in plant growth and development.[1] [2]
  • Arabinogalactan proteins might be soluble signals, or might act as modulators and coreceptors of apoplastic morphogens; their amphiphilic molecular nature makes them prime candidates of mediators between the cell wall, the plasma membrane, and the cytoplasm.[1] [2]


  • The RT-qPCR analysis reveal that several rice AGP-encoding genes are predominantly expressed in anthers and display differential expression patterns in response to abscisic acid, gibberellic acid, and abiotic stresses.[1]


  • Proteoglycans or glycoproteins are basal components of the cell wall implicated in various processes of plant growth and development throughout the plant kingdom. A large number of these proteins are rich in proline (Pro) or hydroxyproline (Hyp) and are named Pro-rich/Hyp-rich glycoproteins (P/HRGPs). [1]
  • The P/HRGPs share common features that consist of regions containing Hyp residues, which are called ‘glycomodules’ and in which most Hyp residues are usually glycosylated by a large branched arabinogalactan (AG) polysaccharide or by small non-branched arabinooligosaccharides (arabinosides).[1]
