盐藻(Thellungiella salsugina(Halophila))是拟南芥的近亲，但与拟南芥不同的是，它在寒冷、盐碱、干旱和氮素限制的极端条件下生长良好。在过去的十年里，许多实验室已经开始利用Thellungiella来研究植物非生物胁迫耐受的生理、代谢和分子机制，特别是在离子转运和基因表达方面取得了新的知识。与其他极端环境模式植物相比，Thellungiella的优势在于它可以直接与拟南芥进行比较，从而产生关于逆境耐受性的基本和关键组成部分的信息。Thellungiella的研究得到了越来越多的技术资源的支持，包括生理和分子方案、生态型收集、表达序列标签、cDNA文库、微阵列和待定的基因组序列。本文综述了海藻的研究现状，并对其作为植物抗逆性研究模型的有效性进行了重新评价。
Thellungiella salsuginea (halophila) is a close relative of Arabidopsis thaliana but, unlike A. thaliana, it grows well in extreme conditions of cold, salt, and drought as well as nitrogen limitation. Over the last decade, many laboratories have started to use Thellungiella to investigate the physiological, metabolic, and molecular mechanisms of abiotic stress tolerance in plants, and new knowledge has been gained in particular with respect to ion transport and gene expression. The advantage of Thellungiella over other extremophile model plants is that it can be directly compared with Arabidopsis, and therefore generate information on both essential and critical components of stress tolerance. Thellungiella research is supported by a growing body of technical resources comprising physiological and molecular protocols, ecotype collections, expressed sequence tags, cDNA-libraries, microarrays, and a pending genome sequence. This review summarizes the current state of knowledge on Thellungiella and re-evaluates its usefulness as a model for research into plant stress tolerance.
