Os05g0140100

The rice Os05g0140100 was reported as OsMYB2P-1 in 2012 by researchers from China.

Annotated Information

Function

• The rice OsMYB2P-1 encodes R2R3 MYB Transcription Factor.
• OsMYB2P-1 is Involved in the Regulation of Phosphate-Starvation Responses and Root Architecture in Rice.

Phenotypic analysis

• Overexpression of OsMYB2P-1 in Arabidopsis (Arabidopsis thaliana) and rice enhanced tolerance to Pi starvation, while suppression of OsMYB2P-1 by RNA interference in rice rendered the transgenic rice more sensitive to Pi deficiency.
• Furthermore, primary roots of OsMYB2P-1-overexpressing plants were shorter than those in wild-type plants under Pi-sufficient conditions, while primary roots and adventitious roots of OsMYB2P-1- overexpressing plants were longer than those of wild-type plants under Pi-deficient conditions.
• These results suggest that OsMYB2P-1 may also be associated with the regulation of root system architecture.

Expression

• Expression of OsMYB2P-1 was induced by Pi starvation.
• Overexpression of OsMYB2P-1 led to greater expression of Pi-responsive genes such as Oryza sativa UDP-sulfoquinovose synthase, OsIPS1, OsPAP10, OsmiR399a, and OsmiR399j.
• In contrast, overexpression of OsMYB2P-1 suppressed the expression of OsPHO2 under both Pi-sufficient and Pi-deficient conditions.

Subcellular localization

• OsMYB2P-1 was localized in the nuclei and exhibited transcriptional activation activity.
