Physiological Characterization of Two Genes for Na+ Exclusion in Durum Wheat, Nax1 and Nax2
Open accessAbstract
Durum wheat (Triticum turgidum L. subsp. durum Desf.) Line 149 contains two novel major genes for excluding Na(+) from leaf blades, named Nax1 and Nax2. The genes were separated into families containing a single gene and near-isogenic homozygous lines were selected. Lines containing either Nax1 or Nax2 had lower rates of Na(+) transport from roots to shoots than their near-isogenic pairs due to lower rates of net loading of the xylem, not to lower rates of net uptake from the soil or higher rates of retranslocation in the phloem. Nax1 and Nax2 lines also had higher rates of K(+) transport from root to shoot, resulting in an enhanced discrimination of K(+) over Na(+). Lines containing Nax1 differed from those containing Nax2 by unloading Na(+) from the xylem as it entered the shoot so that Na(+) was retained in the base of the leaf, leading to a high sheath to blade ratio of Na(+) concentration. Gradients in tissue concentrations of Na(+) along the leaf suggested that Na(+) was continually removed from the xylem. The Nax2 line did not retain Na(+) in the base of the leaf, suggesting that it functioned only in the root. The Nax2 gene therefore has a similar function to Kna1 in bread wheat (Triticum aestivum).

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.
