The Nitrate Transporter AtNRT1.1 (CHL1) Functions in Stomatal Opening and Contributes to Drought Susceptibility in Arabidopsis
Open accessAbstract
The movement of guard cells in stomatal complexes controls water loss and CO(2) uptake in plants. Examination of the dual-affinity nitrate transporter gene AtNRT1.1 (CHL1) revealed that it is expressed and functions in Arabidopsis guard cells. CHL1 promoter-beta-glucuronidase and CHL1 promoter-green fluorescent protein constructs showed strong expression in guard cells, and immunolocalization experiments with anti-CHL1 antibody confirmed these results. To assess CHL1 function, chl1 mutant plants grown in the presence of nitrate were examined. Compared with wild-type plants, chl1 mutants had reduced stomatal opening and reduced transpiration rates in the light or when deprived of CO(2) in the dark. These effects result in enhanced drought tolerance in chl1 mutants. At the cellular level, chl1 mutants showed reduced nitrate accumulation in guard cells during stomatal opening and failed to show nitrate-induced depolarization of guard cells. In wild-type guard cells, nitrate induced depolarization, and nitrate concentrations increased threefold during stomatal opening. These results identify an anion transporter that functions in stomatal opening and demonstrate that CHL1 supports stomatal function in the presence of nitrate.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
