additional information | in nitrate-containing media, NRT2.4 expression is detected at low levels in roots and undetectable in shoots, but is induced after 3 days of nitrogen starvation 12fold in roots and detectable in shoots. NRT2.1 expression is high in roots in the presence of external nitrate and, after a transient increase, is relatively unchanged after 3 days of nitrogen starvation | Arabidopsis thaliana | - |
root | NRT2.4 expression in lateral root epidermal cells. NRT2.1 expression in the older part of the primary root regardless of nitrogen status | Arabidopsis thaliana | - |
shoot | NRT2.4 expression in shoots is limited to the primary veins of leaves and inflorescences and is adjacent to the phloem parenchyma | Arabidopsis thaliana | - |

General Information | Comment | Organism |

physiological function | NRT2.1 is a prominent high-affinity nitrate transporter that functions at low external nitrate concentrations and plays an additional role in lateral root initiation that is independent of this transport function. NRT2.4 is a high-affinity nitrate transporter important in both root uptake and phloem loading and that its spatial and temporal expression complements that of NRT2.1 | Arabidopsis thaliana |
