Physiology and molecular biology of stress tolerance in plants (2006, background): “…in moderately tolerant crops, such as bread wheat, salt tolerance is associated with low rates of sodium transport to the shoots and high K+/Na+ discrimination (Gorham, 1990), which was also shown for the tetraploid Triticum turgidum, subspecies durum (Munns et al., 2000; Munns and James, 2003).”
Improving salinity tolerance in crop plants: a biotechnological view (2008, background): “2008) or under controlled environmental conditions (Kingsbury and Epstein 1984; Rawson et al. 1988; Munns et al. 2000; Mohammadi-Nejad et al. 2008).”
Mechanisms of sodium uptake by roots of higher plants (2009, background): “Salt resistance in bread wheat is linked with a locus on the D genome that results in low Na+ uptake and enhanced K+/Na+ discrimination (Munns et al. 2000).”
Evaluating salt tolerance of wheat genotypes using multiple parameters (2005, background): “When the developmental pattern of genotypes is so different between growth stages, assessment of the actual salt tolerance of the genotypes may be determined by comparisons of their biomass production over a long growth period ( Leland et al., 1994; Munns et al., 2000), which therefore serve as anot”
Approaches to increasing the salt tolerance of wheat and other cereals. (2006, background): “For example, in wheat growing in 120 mM NaCl, Na+ in the growing tissues of leaves was at most only 20 mM, and only 10 mM in the rapidly expanding zones, and Cl only about 50 mM (Hu et al., 2005).”
Avenues for increasing salt tolerance of crops, and the role of physiologically based selection traits (2002, methodology): “Low Na+ accumulation (and high K+/Na+ discrimination) of similar magnitude to that of bread wheat was found in a landrace from the sub-species durum (Munns et al., 2000).”
Physiological traits and cereal germplasm for sustainable agricultural systems (2007, background): “However, cereal species also vary markedly (Munns et al., 2000b).”
Salinity Stress in Wheat: Effects, Mechanisms and Management Strategies (2021, background): “5 Molecular Mechanisms Tetraploid wheat is relatively salt-sensitive as compared to bread wheat [83].”
EVALUATION OF SORGHUM VARIETIES/LINES FOR SALT TOLERANCE USING PHYSIOLOGICAL INDICES AS SCREENING TOOL (2012, background): “Several workers have proved that tolerance of plants in their rooting medium is under genetic control (Munns et al., 2000).”
Salinity Tolerance in Brassica Oilseeds (2004, background): “Such type of exclusion mechanism has already been reported by many scientists (Shannon, 1978; Maas and Nieman, 1978; Läuchli and Wieneke, 1979; Winter and Läuchli, 1982; Wyn Jones et al., 1984; Ashraf and McNeilly, 1990; Munns, 2002, Munns et al., 2003).”
Physiological response of common bean (Phaseolus vulgaris L.) seedlings to salinity stress (2007, background): “In salt-sensitive plant, shoot, and to lesser extent, root growth is permanently reduced within hours of salt tress and this does not appear to depend on Na+ concentrations in the growing tissues, but rather is a response to the osmolatity of the external solution (Munns et al., 2000a; Munns, 2002).”
Selection of callus cultures of sugarcane (Saccharum sp.) tolerant to NaCl and their response to salt stress (2006, background): “Approximately 5% of the cultivated land is affected by salt (Munns et al. 1999).”
