Background  Accumulating evidences show that  SPL s are crucial regulators of plant abiotic stress tolerance and the highly conserved module miR156/ SPL  appears to balance plant growth and stress responses. The halophyte  Tamarix chinensis  is highly resistant to salt tress.  SPL s of  T. chinensis  ( TcSPLs ) and theirs roles in salt stress responses remain elusive.    Results  In this study, we conducted a systematic analysis of the  TcSPLs  gene family including 12 members belonging to 7 groups. The physicochemical properties and conserved motifs showed divergence among groups and similarity in each group. The microRNA response elements (MREs) are conserved in location and sequence, with the exception of first MRE within  TcSPL 5. The miR156-targeted  SPL s are identified by dual-luciferase reporter assay of MRE-miR156 interaction. The digital expression gene profiles cluster suggested potential different functions of miR156-targeted  SPL s vs non-targeted  SPL s in response to salt stress. The expression patterns analysis of miR156-targeted  SPL s with a reverse expression trend to TcmiR156 suggested 1 h (salt stress time) could be a critical time point of post-transcription regulation in salt stress responses.    Conclusions  Our work demonstrated the post-transcription regulation of miR156-targeted  TcSPLs  and transcription regulation of non-targeted  TcSPLs  in salt stress responses, and would be helpful to expound the miR156/ SPL -mediated molecular mechanisms underlying  T. chinensis  salt stress tolerance.
