Linking salinity stress tolerance with tissue-specific Na(+) sequestration in wheat roots.

ABSTRACT: Salinity stress tolerance is a physiologically complex trait that is conferred by the large array of interacting mechanisms. Among these, vacuolar Na(+) sequestration has always been considered as one of the key components differentiating between sensitive and tolerant species and genotypes. However, vacuolar Na(+) sequestration has been rarely considered in the context of the tissue-specific expression and regulation of appropriate transporters contributing to Na(+) removal from the cytosol. In this work, six bread wheat varieties contrasting in their salinity tolerance (three tolerant and three sensitive) were used to understand the essentiality of vacuolar Na(+) sequestration between functionally different root tissues, and link it with the overall salinity stress tolerance in this spec
