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.

最近，另一个盐生植物盐芥被提议为研究植物耐盐性的模式系统，它是拟南芥的近缘，为生长周期短、基因组较小、耐盐性较强的十字花科的盐生植物；在cDNA水平上与拟南芥有大约90-95％的同源性，因此，可以方便地将拟南芥的很多信息移至盐芥耐盐性的分子生物学研究；而且，盐芥具有拟南芥很多同样的优点以作为实验系统。
