Recently, Thellungiella halophila, a close-relative ofArabidopsis thaliana, which is been suggested and be developed as a new salttolerance model plant. Thellungiella halophila is a salt-tolerance crucifer with a shortlife cycle, small genome, and with high sequence similarity(about 90-95% on cDNAlevel), similar heredity characteristics and growth habits with Arabidopsis thaliana.So it is convenience for T. halophila to benefit from a lot of Arabidopsis thalianainformation data.
