Role of AMT1;1 in NH4+ acquisition in Arabidopsis thaliana

WebThe NH 4 1 concentration needed to saturate AtAMT1;2 was much higher than for AtAMT1;1, which has a more than 10-fold higher affinity (Mayer and Ludewig, 2006; Wood et al., 2006). 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 … injury florida law firm p.a

WebApr 1, 2001 · Unlike AtNrt2.1, AtAmt1.1 expression is not stimulated in a nitrate reductase-deficient mutant after transfer to NO3- as sole N source, indicating that NO3- per se acts as a signal repressing transcription of AtAmt1.1. These results reveal two fundamentally different types of mechanism involved in the feedback regulation of root N acquisition ... WebJan 4, 2024 · 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. In roots of these lines, however, the steady‐state transcript levels of AtAMT1;1 still significantly decreased under conditions of N‐sufficiency … WebDec 15, 2006 · The high AtAMT1;1 transcript levels in the two transgenic lines 18 and 19 led to accumulation of large amounts of AtAMT1;1 protein, as determined by protein gel-blot analysis using a rabbit antibody targeted against 15 amino acid residues from the loop between the transmembrane-spanning helices 2 and 3 of AtAMT1;1 .
