Physiological, genomic and transcriptomic comparison of two Brassica napus cultivars with contrasting cadmium tolerance

Aims Cadmium (Cd) is the most widespread toxic heavy metal to plant growth. As the second leading oil crop, some genotypes of Brassica napus (B. napus) are potential Cd accumulators. However, the Cd translocation mechanism from root to shoot in B. napus in response to Cd toxicity remains unknown.
