The rice Os11g0592200 was reported as OsMT1a in 2009 [1] by researchers from China.
Contents
Annotated Information
Function
- Metallothioneins (MTs) are small, cysteine-rich, metal-binding proteins that may be involved in metal homeostasis and detoxification in both plants and animals.
- OsMT1a, encodes a type 1 metallothionein.
Phenotypic analysis
- Both transgenic plants and yeasts harboring OsMT1a accumulated more Zn(2+) than wild type controls, suggesting OsMT1a is most likely to be involved in zinc homeostasis.
- Transgenic rice plants overexpressing OsMT1a demonstrated enhanced tolerance to drought.
- The examination of antioxidant enzyme activities demonstrated that catalase (CAT), peroxidase (POD) and ascorbate peroxidase (APX) were significantly elevated in transgenic plants. Furthermore, the transcripts of several Zn(2+)-induced CCCH zinc finger transcription factors accumulated in OsMT1a transgenic plants, suggesting that OsMT1a not only participates directly in ROS scavenging pathway but also regulates expression of the zinc finger transcription factors via the alteration of Zn(2+) homeostasis, which leads to improved plant stress tolerance.
Expression
- Expression analysis revealed that OsMT1a predominantly expressed in the roots, and was induced by dehydration.
- The OsMT1a expression was also induced specifically by Zn treatment.
