Hemicellulose modification promotes cadmium hyperaccumulation by decreasing its retention on roots in Sedum alfredii

Aims As a vital polysaccharide related to mechanisms of plant resistance to trace metal in the root cell wall, the role of hemicellulose in cadmium (Cd) accumulation in hyperaccumulators is still unknown. We investigated hemicellulose modification in response to Cd in two populations of Sedum alfredii.
