Changes in gene expression in Camelina sativa roots and vegetative tissues in response to salinity stress.

ABSTRACT: The response of Camelina sativa to salt stress was examined. Salt reduced shoot, but not root length. Root and shoot weight were affected by salt, as was photosynthetic capacity. Salt did not alter micro-element concentration in shoots, but increased macro-element (Ca and Mg) levels. Gene expression patterns in shoots indicated that salt stress may have led to shuttling of Na⁺ from the cytoplasm to the tonoplast and to an increase in K⁺ and Ca⁺² import into the cytoplasm. In roots, gene expression patterns indicated that Na⁺ was exported from the cytoplasm by the SOS pathway and that K⁺ was imported in response to salt. Genes involved in chelation and storage were up-regulated in shoots, while metal detoxification appeared to involve v
