Gene Details:

• MSU gene ID: LOC_Os01g61380
• RAPdb gene ID: Os01g0829800
• Gene Symbol: OsMDH1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The OsMDH1 was expressed in different tissues of rice plants including leaf, leaf sheath, panicle, glume, bud, root, and stem and was induced in the presence of NaCl.
• Transient expression of OsMDH1-GFP in rice protoplasts showed that OsMDH1 localizes to chloroplast.
• In this study, we identified a new loss-of-function OsMDH1 mutant displaying salt stress-tolerant phenotype.
• Transgenic rice plants overexpressing OsMDH1 (OsMDH1OX) displayed a salt stress-sensitive phenotype.
• Moreover, the pyridoxine content was higher in the OsMDH1 mutant and lower in OsMDH1OX plants than in the NIP plants under the salt stress, indicating that OsMDH1 negatively regulates salt stress-induced pyridoxine accumulation.
• Together, our results establish a novel, negative regulatory role of OsMDH1 in salt stress tolerance by affecting vitamin B6 content of rice tissues.
