Characterization of the multigene family TaHKT 2;1 in bread wheat and the role of gene members in plant Na+ and K+ status

A member of the TaHKT2;1 multigene family was previously identified as a Na+ transporter with a possible role in root Na+ uptake. In the present study, the existing full-length cDNA of this member was used as a basis to query the International Wheat Genome Survey Sequence to identify all members of the TaHKT2;1 family.
