The rice Os04g0620000 was reported as OsABCC1 in 2014 [1] by researchers from Korea and Japan.
Contents
Annotated Information
Gene Symbol
- Os04g0620000 <=> OsABCC1,ABCC1,OsMRP1,MRP1
Function
- OsABCC1 is a member of Oryza sativa C-type ATP-binding cassette (ABC) transporter (OsABCC) family, which is involved in the detoxification and reduction of As in rice grains.
- Knockout of OsABCC1 in rice resulted in decreased tolerance to As, but did not affect cadmium toxicity. At the reproductive growth stage, the As content was higher in the nodes and in other tissues of wild-type rice than in those of OsABCC1 knockout mutants, but was significantly lower in the grain.
- OsABCC1 limits As transport to the grains by sequestering As in the vacuoles of the phloem companion cells of the nodes in rice.
Expression
- OsABCC1 was expressed in many organs, including the roots, leaves, nodes, peduncle, and rachis. Expression was not affected when plants were exposed to low levels of As but was up-regulated in response to high levels of As.
Subcellular localization
- In both the basal nodes and upper nodes, which are connected to the panicle, OsABCC1 was localized to the phloem region of vascular bundles.
- OsABCC1 was localized to the tonoplast and conferred phytochelatin-dependent As resistance in yeast.
