Gene Details:

• MSU gene ID: LOC_Os01g02120
• RAPdb gene ID: Os01g0111600
• Gene Symbol: OsMFT2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In vivo and in vitro assays showed that three bZIP transcription factors, OsbZIP23, OsbZIP66 and OsbZIP72, interacted with OsMFT2.
• Exogenous abscisic acid (ABA) treatment on imbibed seeds and seedlings indicated that OsMFT2 altered ABA sensitivity during seed germination and post-germination growth.
• OsMFT2 is involved in the regulation of ABA signaling-mediated seed germination through interacting with OsbZIP23/66/72 in rice.
• All these results demonstrated that OsMFT2 positively regulates ABA response genes through interacting with OsbZIP23/66/72 and functions in seed germination.
• OsbZIP23/66/72 bound to the promoter of Rab16A, a typical ABA responsive element containing gene, and OsMFT2 enhanced their binding activities to Rab16A promoter.
• Moreover, several ABA responsive genes were differentially expressed in the imbibed seeds of OsMFT2 transgenic lines and wild-type.
• Performance of transgenic plants demonstrated that overexpressing OsbZIP23 rescued the pre-harvest sprouting phenotype and expression decrease of ABA signaling genes caused by OsMFT2 knocking-out.
• Subcellular localization indicated that OsMFT2 was a nuclear protein.
• Overexpression of OsMFT1 (OsMFT1OE) or OsMFT2 increased the sensitivity to salt stress during seed germination.
• In this study, we found that seeds of loss-of-function osmft1 mutants germinated faster than wild-type (WT) seeds under salt stress, but this was not the case for loss-of-function OsMFT2 mutants.
