| Title: Nramp5 is a major transporter responsible for manganese and cadmium uptake in rice .
| | Author: Sasaki A Yamaji N Yokosho K Ma JF | | Journal: Plant Cell Citation: V : 24 P : 2155-67 Year: 2012 Type: In-Data-Review | | Literature: oryza Field: abstract Doc ID: pub22589467 Accession (PMID): 22589467 | | Abstract: Paddy rice ( Oryza sativa ) is able to accumulate high concentrations of Mn without showing toxicity ; however , the molecular mechanisms underlying Mn uptake are unknown .
Here , we report that a member of the Nramp ( for the Natural Resistance-Associated Macrophage Protein ) family , Nramp5 , is involved in Mn uptake and subsequently the accumulation of high concentrations of Mn in rice .
Nramp5 was constitutively expressed in the roots and encodes a plasma membrane-localized protein .
Nramp5 was polarly localized at the distal side of both exodermis and endodermis cells .
Knockout of Nramp5 resulted in a significant reduction in growth and grain yield , especially when grown at low Mn concentrations .
This growth reduction could be partially rescued by supplying high concentrations of Mn but not by the addition of Fe .
Mineral analysis showed that the concentration of Mn and Cd in both the roots and shoots was lower in the knockout line than in wild-type rice .
A short-term uptake experiment revealed that the knockout line lost the ability to take up Mn and Cd .
Taken together , Nramp5 is a major transporter of Mn and Cd and is responsible for the transport of Mn and Cd from the external solution to root cells .

| Title: Characterizing the role of rice NRAMP5 in Manganese , Iron and Cadmium Transport .
| | Author: Ishimaru Y Takahashi R Bashir K Shimo H Senoura T Sugimoto K Ono K Yano M Ishikawa S Arao T Nakanishi H Nishizawa NK | | Journal: Sci Rep Citation: V : 2 P : 286 Year: 2012 Type: In-Data-Review | | Literature: oryza Field: title Doc ID: pub22368778 Accession (PMID): 22368778 | | Abstract: Metals like manganese ( Mn ) and iron ( Fe ) are essential for metabolism , while cadmium ( Cd ) is toxic for virtually all living organisms .
Understanding the transport of these metals is important for breeding better crops .
We have identified that OsNRAMP5 contributes to Mn , Fe and Cd transport in rice .
OsNRAMP5 expression was restricted to roots epidermis , exodermis , and outer layers of the cortex as well as in it issues around the xylem .
OsNRAMP5 localized to the plasma membrane , and complemented the growth of yeast strains defective in Mn , Fe , and Cd transport .
OsNRAMP5 RNAi ( OsNRAMP5i ) plants accumulated less Mn in the roots , and less Mn and Fe in shoots , and xylem sap .
The suppression of OsNRAMP5 promoted Cd translocation to shoots , highlighting the importance of this gene for Cd phytoremediation .
These data reveal that OsNRAMP5 contributes to Mn , Cd , and Fe transport in rice and is important for plant growth and development .
