WebMar 29, 2016 · AtAMT1;1, AtAMT1;3, and AtAMT1;5 act to absorb ammonium directly from the soil, and AtAMT1;2 transports apoplastic amm onium into the cell ( Loque et al. 2006 ; Yuan et al. 2007a) . WebDec 5, 2006 · The exchange in AtAMT1;1 inactivated NH 4 + transport, as determined by growth assays of triple-mepΔ yeast expressing the T460D mutant construct (Fig. 3B). By contrast, the mutation of Thr-460 to the uncharged Ala, which is the corresponding residue in AtAMT1;5, yielded a functional transporter (Fig. 3B).
WebNitrogen is an essential macronutrient for plant growth and survival. Here, the temporal and spatial sensing of nitrogen starvation is analyzed in Arabidopsis (Arabidopsis thaliana).The promoter for the high-affinity ammonium transporter, AtAmt1.1, is shown to be a valid indicator for nitrogen status in leaves and roots.An AtAmt1.1-Gal4 transgene using three … WebJan 20, 2014 · AtAMT1-1 and AtAMT1-3 are plasma membrane localized, and all three are high affinity NH 4 + transporter proteins and involved in root-uptake of NH 4 + in an additive manner [28, 67]. While AtAMT1-3 and AtAMT1-5 are root specific, AtAMT1-1 is expressed more broadly, including roots, leaves, and sepals (Figure 5). In addition to its function in ...
WebWe have compared the biochemical properties of two different Arabidopsis ammonium transporters, AtAMT1;1 and AtAMT1;2, expressed in yeast, with the biophysical properties of ammonium transport in planta. Expression of the AtAMT1;1 gene in Arabidopsis roots increased approximately four-fold in response to nitrogen deprivation. This coincided with … WebJan 1, 2024 · In agreement with a previous study , AtAMT1;5 can access external NH 4 + by uptake across the plasma membrane of rhizodermis cells and is responsible for the residual high-affinity NH 4 + uptake by AtAMT1;1–AtAMT1;3. The OsAMTs protein can promote rice root branching and root system buildup at low NH 4 + concentrations .
