Gene Details:

• MSU gene ID: LOC_Os12g43600
• RAPdb gene ID: Os12g0632000
• Gene Symbol: Osgr-rbp4 Osgrp1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
