Studying heavy metal hyperaccumulation is becoming more and more interesting for ecological, evolutionary, nutritional, and environmental reasons. One model species, especially in the era of high throughput genomics, transcriptomics, proteomics and metabolomics technologies, would be very advantageous. Although there are several hyperaccumulator species known, there is no single model species yet. The Zn, Cd and Ni hyperaccumulator species Thlaspi caerulescens has been studied to a great extent, especially for Zn and Cd hyperaccumulation and tolerance. Its physiological, morphological and genetic characteristics, and its close relationship to Arabidopsis thaliana, the general plant reference species, make it an excellent candidate to be the plant heavy metal hyperaccumulation model species.
出于生态、进化、营养和环境等方面的原因，对重金属超积累的研究正变得越来越有趣。在高通量基因组学、转录组学、蛋白质组学和代谢组学技术的时代，一种模式物种将非常具有优势。尽管已知有几种超积累物种，但目前还没有单一的模式物种。锌、镉和镍超积累物种天蓝遏蓝菜已得到了广泛研究，尤其是在锌和镉的超积累及耐受性方面。其生理、形态和遗传特征，以及它与一般植物参考物种拟南芥的密切关系，使其成为植物重金属超积累模式物种的极佳候选者。
