Characterization of early transcriptional responses to cadmium in the root and leaf of Cd-resistant Salix matsudana Koidz

摘要

BackgroundSalix matsudana Koidz. is a fast growing tree species. It has a high cadmium (Cd) tolerance capacity, making it potentially suitable for phytoremediation. Presently, transcriptomic and physiological Cd response mechanisms are poorly understood. Transcriptomic analysis in early response to high (50 μM) Cd levels was investigated in leaf and root of Cd-resistant S. matsudana Koidz..
