WebDec 5, 2006 · Preferential Localization of AtAMT1;2 in the Plasma Membrane of Endodermal Root Cells. The transcripts of several NH 4 + transporters have been identified in roots, including those of AtAMT1;1 and AtAMT1;2 (Gazzarrini et al., 1999).In apical zones of the roots, the green fluorescent protein (GFP) fusion protein with AtAMT1;1 under the … WebSep 3, 2009 · No currents were elicited by NH 4 +, as well. In contrast, AtAMT1;2-expressing oocytes imported similar amounts of 14 C-MeA and showed large MeA- and ammonium-dependent currents (Fig. 3). The combined data suggest that the transport by AtAMT2 was electroneutral, i.e. that the transported species across the membrane were …
