Gene Symbol
- Os11g0558200 <=> OsMYB4P,MYB4P
Function
- OsMYB4P is an R2R3 MYB transcription factor.
- OsMYB4P may be associated with efficient utilization of Pi in rice through transcriptional activation of Pi homeostasis-related genes.
Phenotypic analysis
- Transcriptional levels of OsMYB4P in cell suspension, shoots, and roots of rice increased under phosphate-deficient conditions.
- Shoots and roots of OsMYB4P-overexpressing plants grew well in high- and phosphate-deficient conditions.
- In addition, root system architecture was altered considerably as a result of OsMYB4P overexpression. Under both phosphate-sufficient and -deficient conditions, more Pi accumulated in shoots and roots of OsMYB4P-overexpressing plants than in the wild type.
- Overexpression of OsMYB4P led to greater expression of Pi transporter-family proteins OsPT1, OsPT2, OsPT4, OsPT7, and OsPT8 in shoots, and to decreased or unchanged expression of these proteins in roots, with the exception of OsPT8.
Expression
- Transcriptional levels of OsMYB4P in cell suspension, shoots, and roots of rice increased under phosphate-deficient conditions.
Subcellular localization
- Subcellular localization showed that OsMYB4P was localized in the nucleus and acted as a transcriptional activator.
