Cell-specific localization of Na+ in roots of durum wheat and possible control points for salt exclusion

Huang, Cheng; Lauchli, Andre; James, Richard A; McCully, Margaret E; Munns, Rana Ellen


Sodium exclusion from leaves is an important mechanism for salt tolerance in durum wheat. To characterize possible control points for Na+ exclusion, quantitative cryo-analytical scanning electron microscopy was used to determine cell-specific ion profiles across roots of two durum wheat genotypes with contrasting rates of Na+ transport from root to shoot grown in 50 mm NaCl. The Na+ concentration in Line 149 (low transport genotype) declined across the cortex, being highest in the epidermal and...[Show more]
