Putting halophytes to work - genetics, biochemistry and physiology.

Halophytes are a small group of plants able to tolerate saline soils whose salt concentrations can reach those found in ocean waters and beyond. Since most plants, including many of our crops, are unable to survive salt concentrations one sixth those in seawater (about 80mM NaCl), the tolerance of halophytes to salt has academic and economic importance. In 2009 the COST Action Putting halophytes to work - from genes to ecosystems was established and it was from contributions to a conference held at the Leibniz University, Hannover, Germany, in 2012 that this Special Issue has been produced. The 17 contributions cover the fundamentals of salt tolerance and aspects of the biochemistry and physiology of tolerance in the context of advancing the development of salt-tolerant crops.
