Gene Details:

• MSU gene ID: LOC_Os02g40530
• RAPdb gene ID: Os02g0618400
• Gene Symbol: OsMPS
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsMPS is induced by salt stress and expressed in vegetative and reproductive tissues.
• Over-expression of OsMPS reduces growth under non-stress conditions, while knockdown plants display increased biomass.
• Expression profiling revealed that OsMPS negatively regulates the expression of EXPANSIN (EXP) and cell-wall biosynthesis as well as phytohormone signaling genes.
• The multiple responses of OsMPS and its target genes to various hormones suggest an integrative function of OsMPS in the cross-talk between phytohormones and the environment to regulate adaptive growth.
• OsMPS expression is induced by abscisic acid and cytokinin, but is repressed by auxin, gibberellin and brassinolide.
• Furthermore, the expression of OsMPS-dependent genes is regulated by auxin, cytokinin and abscisic acid.
• Here, the role of MULTIPASS (OsMPS), an R2R3-type MYB transcription factor of rice, was explored.
• Growth retardation caused by OsMPS over-expression is partially restored by auxin application.
