Roles of the SPL gene family and miR156 in the salt stress responses of tamarisk (Tamarix chinensis).

ABSTRACT:

Background

Accumulating evidences show that SPLs 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. SPLs 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 TcSPL5. The miR156-targeted SPLs are identified by dual-luciferase re
