Open AccessIsolation and functional characterization of a Medicago sativa L. gene, MsLEA3-1
A full-length cDNA of 1,728 nt, called MsLEA3-1, was cloned from alfalfa by rapid amplification of cDNA ends from an expressed sequence tag homologous to soybean pGmPM10 (accession No. AAA91965.1). MsLEA3-1, enco...

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