Background  The C 2 H 2 -type zinc finger proteins (C 2 H 2 -ZFPs) are one of major classes of transcription factors that play important roles in plant growth, development and stress responses. Limit information about the  C   2   H   2   -ZF  genes hinders the molecular breeding in bread wheat ( Triticum aestivum ).    Results  In this study, 457 C 2 H 2 -ZFP proteins (including 253 splice variants), which contain four types of conserved domain (named Q, M, Z, and D), could be further classified into ten subsets. They were identified to be distributed in 21 chromosomes in  T. aestivum . Subset-specific motifs, like NPL-, SFP1-, DL- (EAR-like-motif), R-, PL-, L- and EK-, might make C 2 H 2 -ZFP diverse multifunction. Interestingly, NPL- and SFP1-box were firstly found to be located in C 2 H 2 -ZFP proteins. Synteny analyses showed that only 4 pairs of C 2 H 2  family genes in  T. aestivum , 65 genes in  B. distachyon , 66 genes in  A. tauschii , 68 genes in rice, 9 genes in  Arabidopsis , were syntenic relationships respectively. It indicated that  TaZFPs  were closely related to genes in  Poaceae . From the published transcriptome data, totally 198 of 204  TaC   2   H   2   -ZF  genes have expression data. Among them, 25  TaC   2   H   2   -ZF  genes were certificated to be significantly differentially expressed in 5 different organs and 15 different development stages by quantitative RT-PCR. The 18  TaC   2   H   2   -ZF  genes were verified in response to heat, drought, and heat & drought stresses. According to expression pattern analysis, several  TaZFPs , like  Traes_5BL_D53A846BE.1 , were not only highly expressed in L2DAAs, RTLS, RMS, but also endowed tolerance to drought and heat stresses, making them good candidates for molecular breeding.    Conclusions  This study systematically characterized the TaC 2 H 2 -ZFPs and their potential roles in  T. aestivum . Our findings provide new insights into the  C   2   H   2   -ZF  genes in  T. aestivum  as well as a foundation for further studies on the roles of  TaC   2   H   2   -ZF  genes in  T. aestivum  molecular breeding.
