• Information
  • Symbol: Osgr-rbp4,Osgrp1
  • MSU: LOC_Os12g43600
  • RAPdb: Os12g0632000
• Publication
  • Molecular characterization of a novel isoform of rice Oryza sativa L. glycine rich-RNA binding protein and evidence for its involvement in high temperature stress response, 2007, Plant Science.
  • Expression of the rice Osgrp1 promoter-Gus reporter gene is specifically associated with cell elongation/expansion and differentiation, 1995, Plant Mol Biol.
• Genbank accession number
  • AJ002893
• Key message
  • Osgr-rbp4 transcript in rice seedlings is constitutively expressed as well as regulated by different abiotic stresses including high temperature stress
  • Ectopic over-expression of Osgr-rbp4 cDNA imparts high temperature stress tolerance to wild type yeast cells
  • Thus, the expression of the Osgrp1 gene is closely associated with cell elongation/expansion during the post-mitotic cell differentiation process
  • Expression of the rice Osgrp1 promoter-Gus reporter gene is specifically associated with cell elongation/expansion and differentiation
  • The Osgrp1-Gus gene was also expressed in response to wounding and down-regulated by water-stress conditions in the elongation region of roots
  • It is shown that OsGR-RBP4 in rice leaf cells and its immunologically homologous protein in tobacco BY2 protoplasts are nuclear proteins
  • To study the expression and regulation of a rice glycine-rich cell wall protein gene, Osgrp1, transgenic rice plants were regenerated that contain the Osgrp1 promoter or its 5’ deletions fused with the bacterial beta-glucuronidase (GUS) reporter gene
