Identification of stress tolerance related genes via FOX hunting of Thellungiella halophila full-length cDNA

Thellungiella halophila has been identified as a model system for understanding abiotic stress tolerance, and it shows extreme salt tolerance. Recently, full-length cDNA library with a total of 9,569 unique genes were constructed from Thellungiella plants treated with salinity, cold, freezing stresses or ABA treatment (Taji et al.,2008). Using ectopic expression of full-length cDNAs, a novel gain-of-function system, termed the FOX hunting system (Full-length cDNA Over-eXpressing gene hunting system) was developed. We identified 3 salt-, 2 osmo- and 4 heat-tolerance related genes using the FOX hunting.
