RNA-seq of Jing724 and Mo17 BC1 population, low cadmium pool
To map and clone the kernel cadmium  content-related genes, three BC1 populations, (B73/Mo17)/Mo17,  (Jing724/Mo17)/Mo17 and (Huangzaosi/Mo17)/Mo17 were generated.Of these  materials, Mo17 is a maize inbred line with higher cadmium content in grains  while B73, Jing724 and Huangzaosi are the inbred lines with lower cadmium  content. Three independent BSR-seq assays were carried out to map the main  kernel cadmium content-related genes with the RNAs of two extreme plant pools  (low cadmium content pool and high cadmium content pool) from the three BC1  populations, respectively.
