Six maize ERF genes were isolated and designated asZmERF4, ZmERF26, ZmERF28, ZmERF64, ZmERF89 and ZmERF202,respectively. Results of analyzing gene structure showed that the structures of the maize ZmERF genes isolated were different from those of Arabidopsis AtERF. Results of phylogenetic analysis showed that ZmERFs had a closer relation to OsERFs and a little far relation to AtERFs. Results of expression analysis showed that mRNAs of all six ZmERFs were accumulated firstly and then declined in leaves,whereas the expressions of 4 genes including ZmERF4, ZmERF28,ZmERF64 and ZmERF89 were down-regulated in roots under ET treatment. mRNAs of 6 ERFs were regulated more or less in leaves,whereas expressions of most ZmERFs in roots were not changed significantly under ABA or JA treatment,especially for JA treatment. It is indicated that the ZmERFs might play different roles in hormone signaling pathway of maize leaves and roots.
