Background Maize ( Zea mays  L.) is a widely cultivated cereal and has been used as an optimum heavy metal phytoremediation crop. Metallothionein (MT) proteins are small, cysteine-rich, proteins that play important roles in plant growth and development, and the regulation of stress response to heavy metals. However, the MT genes for maize have not been fully analyzed so far. Methods The putative  ZmMT  genes were identified by HMMER.The heat map of  ZmMT  genes spatial expression analysis was generated by using R with the log 2  (FPKM + 1).The expression profiles of  ZmMT  genes under three kinds of heavy metal stresses were quantified by using qRT-PCR. The metallothionein proteins was aligned using MAFFT and phylogenetic analysis were constructed by ClustalX 2.1. The protein theoretical molecular weight and pI, subcellular localization, TFs binding sites, were predicted using ProtParam, PSORT, PlantTFDB, respectively. Results A total of 9  ZmMT  genes were identified in the whole genome of maize. The results showed that eight of the nine ZmMT proteins contained one highly conserved metallothio_2 domain, while ZmMT4 contained a Metallothio_PEC domain. All the ZmMT proteins could be classified into three major groups and located on five chromosomes. The  ZmMT  promoters contain a large number of hormone regulatory elements and hormone-related transcription factor binding sites. The  ZmMT  genes exhibited spatiotemporal specific expression patterns in 23 tissues of maize development stages and showed the different expression patterns in response to Cu, Cd, and Pb heavy metal stresses. Conclusions We identified the 9  ZmMT  genes, and explored their conserved motif, tissue expression patterns, evolutionary relationship. The expression profiles of  ZmMT  genes under three kinds of heavy metal stresses (Cu, Cd, Pb) were analyzed. In summary, the expression of  ZmMTs  have poteintial to be regulated by hormones. The specific expression of  ZmMT s in different tissues of maize and the response to different heavy metal stresses are revealed that the role of MT in plant growth and development, and stress resistance to heavy metals.
