The plant MT1 metallothioneins are stabilized by binding cadmiums and are required for cadmium tolerance and accumulation.

Plant molecular biology - 1 Aug 2005

Abstract excerpt

The small Arabidopsis genome contains nine metallothionein-like (MT) sequences with classic, cysteine-rich domains separated by spacer sequences, quite unlike the small conserved MT families found vertebrate genomes. Phylogenetic analysis revealed four ancient and divergent classes of plant MTs that predate the monocot-dicot divergence. A distinct cysteine spacing pattern suggested differential metal ion...
