Gene Details:

• MSU gene ID: LOC_Os10g40710
• RAPdb gene ID: Os10g0555700
• Gene Symbol: OsEXPB2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• A clear difference was observed between RNA interference (RNAi) lines and wild-type in root system architecture and plant height, and the suppression of OsEXPB2 resulted in a visible alteration of the width of the leaf blade.
• The OsEXPB2 promoter contains conserved root hair-specific elements.
• Analysis of spatial and temporal expression patterns demonstrated that OsEXPB2 was predominantly expressed in root of rice.
• All these results suggest that OsEXPB2 is a root-predominant gene with a key role in root-hair formation and has the potential to be utilized in transgenic root breeding to improve abiotic stress tolerance.
• OsEXPB2 expression levels were up-regulated by abiotic stresses, such as phosphate or iron deficiency, and also suppressed by abscisic acid.
• Subcellular localization assay revealed that OsEXPB2 was localized in the cell wall.
