Genetic architecture of cadmium tolerance in the hyperaccumulator Arabidopsis halleri: fine-mapping and variability within the spe.

The article discusses the cadmium tolerance and accumulation in the hyperacccumulators including Noccaea caerulescens and Arabidopsis halleri, the later seemed to show more tolerance towards Cd and a cross between A. halleri and a non tolerant relative was found with additional genes.
