GT Transcription Factors of Rosa rugosa Thunb. Involved in Salt Stress Response.

ABSTRACT: Rosa rugosa was a famous aromatic plant while poor salt tolerance of commercial cultivars has hindered its culture in saline-alkali soil. In many plants, the roles of GT (or trihelix) genes in salt stresses responses have been emerging. In the wild R. rugosa, a total of 37 GTs (RrGTs) were grouped into GT-1, GT-2, GTγ, SH4, and SIP1 lineages. SIP1 lineage expanded by transposition. The motifs involved in the binding of GT cis-elements were conserved. Four RrGTs (RrGT11/14/16/18) significantly differentially expressed in roots or leaves under salt stress. The responsive patterns within 8 h NaCl treatment indicated that RrGTγ-4 (RrGT18) and RrGT-1 (RrGT16) were significantly induced by salt in roots of R.
