A sodium transporter (HKT7) is a candidate for Nax1, a gene for salt tolerance in durum wheat.
Durum wheat (Triticum turgidum subsp. durum) is more salt sensitive than bread wheat (Triticum aestivum). A novel source of Na(+) exclusion conferring salt tolerance to durum wheat is present in the durum wheat Line 149 derived from Triticum monococcum C68-101, and a quantitative trait locus contributing to low Na(+) concentration in leaf blades, Nax1, mapped to chromosome 2AL. In this study, w...
متن کاملFunctional characterization in Xenopus oocytes of Na+ transport systems from durum wheat reveals diversity among two HKT1;4 transporters
Plant tolerance to salinity constraint involves complex and integrated functions including control of Na(+) uptake, translocation, and compartmentalization. Several members of the high-affinity K(+) transporter (HKT) family, which comprises plasma-membrane transporters permeable to K(+) and Na(+) or to Na(+) only, have been shown to play major roles in plant Na(+) and K(+) homeostasis. Among th...
متن کاملSome Physiological and Biochemical Effects of NaCl Salinity on Durum Wheat (Triticum durum Desf.)
The main objective of this study was to examine the effects of NaCl on the leaf growth and some physiological and biochemical characteristics of an Algerian durum wheat (var. Waha) landrace. NaCl (150 mM), as compared to control plants, significantly reduced all the leaf-growth parameters as leaf area (33%), leaf dry weight (41%) and leaf fresh weight (32%), but did not induce any change in the...

In vitro salt tolerance of 28 cultivars of durum wheat with native and exotic origins was investigated, using MS medium containing sodium chloride. The resulting calli were subjected to 8 salinity levels including 0, 0.3, 0.6, 0.9, 1.2, 1.5 and 1.8 percent NaCl (w/v). Donor plants of explant (immature embryo) were grown in a recirculating hydroponics and pots in a greenhouse as well as in the f...
متن کاملControl of sodium transport in durum wheat.
In many species, salt sensitivity is associated with the accumulation of sodium (Na(+)) in photosynthetic tissues. Na(+) uptake to leaves involves a series of transport steps and so far very few candidate genes have been implicated in the control of these processes. In this study, Na(+) transport was compared in two varieties of durum wheat (Triticum turgidum) L. subsp. durum known to differ in...
