- Key message
- Role of the iron transporter OsNRAMP1 in cadmium uptake and accumulation in rice
- The growth of yeast expressing OsNRAMP1 was impaired in the presence of Cd compared with yeast transformed with an empty vector
- The role of the iron transporter OsNRAMP1 in Cd uptake and transport in rice was investigated here
- The OsNRAMP1 iron transporter is involved in Cd accumulation in rice
- The expression of OsNRAMP1 in the roots was higher in a high Cd-accumulating cultivar (Habataki) than a low Cd-accumulating cultivar (Sasanishiki) regardless of the presence of Cd, and the amino acid sequence of OsNRAMP1 showed 100% identity between Sasanishiki and Habataki
- These results suggest that OsNRAMP1 participates in cellular Cd uptake and Cd transport within plants, and the higher expression of OsNRAMP1 in the roots could lead to an increase in Cd accumulation in the shoots
- Rice has seven putative metal transporter NRAMP genes, but microarray analysis showed that only OsNRAMP1 is highly up-regulated by iron (Fe) deficiency
- OsNRAMP1 expression was observed mainly in roots and was higher in the roots of a high-Cd-accumulating cultivar (Habataki) than in those of a low-Cd-accumulating cultivar (Sasanishiki)
- These results suggest that OsNRAMP1 participates in cellular Cd uptake and that the differences observed in Cd accumulation among cultivars are because of differences in OsNRAMP1 expression levels in roots
- Immunostaining showed that OsNRAMP1 was localized in all root cells except the central vasculature, and in leaf mesophyll cells
- The knockout of OsNRAMP1 resulted in significant decreases in root uptake of Cd and Mn and their accumulation in rice shoots and grains, and increased sensitivity to Mn deficiency
- OsNRAMP1 contributes to cadmium and manganese uptake in rice
- Here, we showed that OsNRAMP1 was able to transport Cd and manganese (Mn) when expressed in yeast, but did not transport Fe or As
- OsNRAMP1 was mainly expressed in roots and leaves and encoded a plasma membrane-localized protein
- Previous studies reported that the rice OsNRAMP1 (Natural Resistance-Associated Macrophage Protein 1) could transport iron (Fe), Cd and arsenic (As) in heterologous yeast assays
- OsNRAMP1 expression was induced by Cd treatment and Fe deficiency
- The rice heavy metal transporter OsNRAMP1 regulates disease resistance by modulating ROS homeostasis.
- The osnramp1 mutants had increased content of H(2) O(2) and activity of superoxide dismutase, but decreased activity of catalase, exhibiting enhanced broad-spectrum resistance against bacterial and fungal pathogens
- Altered expression of metal ion-dependent ROS-scavenging enzymes genes and lower accumulation of cations such as Mn coordinately triggered compromised metal ion-dependent enzyme-catalyzing activity and modulated ROS homeostasis, which together contributed to disease resistance in osnramp1 mutants
- Taken together, a proof-of-concept was achieved that broad-spectrum disease resistance and toxic heavy metal-safe rice was engineered by removal of OsNRAMP1 gene
- Here, we show that rice heavy metal transporter OsNRAMP1 plays important roles in plant immunity by modulating metal ions and reactive oxygen species (ROS) homeostasis
- Connection
- OsNRAMP1, OsNRAMP5, OsNRAMP1 contributes to cadmium and manganese uptake in rice , The knockout of OsNRAMP1 had smaller effects on Cd and Mn uptake than knockout of OsNRAMP5, while knockout of both genes resulted in large decreases in the uptake of the two metals
- OsNRAMP1, OsNRAMP5, OsNRAMP1 contributes to cadmium and manganese uptake in rice , Taken together, OsNRAMP1 contributes significantly to the uptake of Mn and Cd in rice and the functions of OsNRAMP1 and OsNRAMP5 are similar but not redundant
- OsNRAMP1, OsNRAMP5, Calcium Plays a Double-Edged Role in Modulating Cadmium Uptake and Translocation in Rice, Our results showed that the supplement of 5 mM Ca significantly reduced Cd uptake by rice roots, because of their competition for Ca-permeable channels as an absorption site and Ca-induced downregulation of OsNRAMP1 and OsNRAMP5
