Transcriptional response in root tips of sweet potato treated with different cadmium and potassium levels

Sweet potato is the seventh most important food crop in the world. Potassium (K) deficiency could affect cadmium (Cd) accumulation in some crops. To investigate the effect of K to Cd accumulation in sweet potato, 12 cDNAs libraries (three biological replicates each treatment) were constructed and sequence by RNA-sequencing.
