盐分是一种非生物胁迫，限制了产量和农作物向新地区的扩展。在过去的20年里，由于分子、基因组学和生物信息学分析领域先进工具的积极发展，我们对植物耐受性和适应盐碱环境的机制的基本了解得到了极大的提高。然而，由于盐生植物作为模式系统在植物耐盐性研究中的应用在很大程度上被忽视，研究力量的全部潜力尚未得到充分开发。最近引进的盐生拟南芥-相关模式种（ARMS）已经开始比较和涉及到一些独特的遗传资源，以完善的拟南芥模式。为了开始通过遗传分析来寻找候选物以了解耐盐性的生物学基础，比较了拟南芥的11种野生近缘植物：野芥、荠菜、Hirschfeldia incana、密花独行菜、Malcolmia triloba、独行菜、播娘蒿、大蒜芥、小盐芥、盐芥（以前称为T. halophila）和Thlaspi arvense。其中耐盐性强的（L. densiflorum和L. virginicum）和中度耐盐（M. triloba和H.物种被发现。只有T。parvula揭示了一个真正的盐生植物的习性，比较好的研究盐芥。生长，水分运输特性和离子积累的主要差异进行了观察和讨论，以描述独特的性状和生理反应，现在可以在盐胁迫研究中进行遗传研究。
Salinity is an abiotic stress that limits both yield and the expansion of agricultural crops to new areas. In the last 20 years our basic understanding of the mechanisms underlying plant tolerance and adaptation to saline environments has greatly improved owing to active development of advanced tools in molecular, genomics, and bioinformatics analyses. However, the full potential of investigative power has not been fully exploited, because the use of halophytes as model systems in plant salt tolerance research is largely neglected. The recent introduction of halophytic Arabidopsis-Relative Model Species (ARMS) has begun to compare and relate several unique genetic resources to the well-developed Arabidopsis model. In a search for candidates to begin to understand, through genetic analyses, the biological bases of salt tolerance, 11 wild relatives of Arabidopsis thaliana were compared: Barbarea verna, Capsella bursa-pastoris, Hirschfeldia incana, Lepidium densiflorum, Malcolmia triloba, Lepidium virginicum, Descurainia pinnata, Sisymbrium officinale, Thellungiella parvula, Thellungiella salsuginea (previously T. halophila), and Thlaspi arvense. Among these species, highly salt-tolerant (L. densiflorum and L. virginicum) and moderately salt-tolerant (M. triloba and H. incana) species were identified. Only T. parvula revealed a true halophytic habitus, comparable to the better studied Thellungiella salsuginea. Major differences in growth, water transport properties, and ion accumulation are observed and discussed to describe the distinctive traits and physiological responses that can now be studied genetically in salt stress research.
