Genome-wide identification and expression analysis of the Trihelix transcription factor family in potato (Solanum tuberosum L.) during development.

ABSTRACT: Trihelix transcription factors (TF) are photoresponsive proteins featuring a characteristic three-helix structure (helix-loop-helix-loop-helix) and contain the Myb/SANT-LIKE (MSL) domain. They perform crucial functions in the development and stress-response of plants. However, the function of the Trihelix TF in potato (Solanum tuberosum L.) remains unknown. In the present study, forty-three StMSLs were characterized in the potato genome and named StMSL1 to StMSL43. Structural domain analysis revealed that motifs 1 and 2 may play a central role in the implementation of trihelix gene functions, and motifs 4 and 9 may be related to specific functions of StMSL. Phylogenetic analysis divided the StMSLs into six groups (SIP1, GT1, GT2, GTγ, SH4 and GT3). The GT3 group
