WebNov 1, 2002 · Results are the first in plant evidence that AtAMT1;1 is a root NH4 + transporter and that redundancies within the AMT family may allow compensation for the loss of AtAMMT 1;1. NH4 + acquisition by plant roots is thought to involve members of the NH4 +transporter family (AMT) found in plants, yeast, bacteria, and mammals. In … WebApr 1, 2024 · While most AMTs are highly expressed in the root, AtAMT1;4 expression is limited to the pollen grains and the pollen tube. Here, we addressed the transport …

WebThe siRNAs for S-PTGS may derive from the aberrant RNA, of which the production was co-determined by sequence feature and excessive expression of AtAMT1;1. Switching to the expression of AtAMT1;1 driven by ProAtUBQ10 or of AtAMT1;1 mutated at two siRNA-targeted hotspots reduced AtAMT1;1-specific siRNAs and overcame S-PTGS in roots. WebJul 1, 2006 · AtAMT1;1 elicited NH4+ and methylammonium (MeA+) inward currents that saturated in a voltage-dependent manner with a half maximal concentration of 2.7 +/- 1.6 microM for NH4+ and 5.0 +/- 0.7 microM for the transport analogue methylammonium. AtAMT1;1 was plasma membrane localized and expressed in the root cortex and … narrow backfill meaning

WebHere, we addressed the transport characteristics of AtAMT1;4 in the heterologous Xenopus laevis oocytes system. The transport saturated and showed high affinity for ammonium … WebHere, we show that AtAMT1;2 has a distinct role, as it is located in the plasma membrane of the root endodermis. AtAMT1;2 functions as a comparatively low-affinity NH4+ transporter. Mutations at the highly conserved carboxyl terminus (C terminus) of AMTs, including one that mimics phosphorylation at a putative phosphorylation site, impair NH4 ... WebDec 5, 2006 · Here, it is shown that AtAMT1;2 is a comparatively low-affinity NH4+transporter that is preferentially localized in the root endodermis.
