title: Genome-wide identification and expression profiling analysis of trihelix gene family in tomato.
abstract: The trihelix family, classified as GT factors due to their binding specificity for GT elements, constitutes a plant-specific transcription factor family with a conserved trihelix DNA binding domain. In the present study, the comprehensive analysis of 36 putative GT factors was performed in tomato. SlGT members can be classified into six subgroups (GT-1, GT-2, SH4, SIP1, GT-γ and GT-δ). Expression analysis of SlGT gene transcripts showed the distinct expression patterns of SlGT genes in various tomato organs. All the SlGT genes were regulated in response to various abiotic stresses and hormone treatments by the quantitative real-time PCR (qRT-PCR) analysis. Several SlGT genes, including SlGT-27 and SlGT-34, were highly regulated by multiple abiotic stresses and phytohormone treatments. Taken together, our results presented here would be providing a useful platform for molecular clone and functional identification of SlGT genes in tomato.
