Genome-wide identification and characterization of the Trihelix transcription factor family and functional analysis of VaTrihelix23 under low temperatures stress in Vitis amurensis.

ABSTRACT:

Background

Trihelix is a class of transcription factors unique to plants that play a major role in abiotic and biotic stress responses, seed isolate development, floral organ morphogenesis, and plant photomorphogenesis. Nevertheless, the Trihelix transcription factor family in Vitis amurensis Rupr. (V. amurensis) has not been systematically characterized.

Results

In this study, 31 VaTrihelix genes were identified in V. amurensis, unevenly distributed across 16 chromosomes with phenomena of clustering. These genes encode hydrophilic proteins (158-858 amino acids) rich in α-helices, predominantly localized in the nucleus. Proteins sharing similar conserved motifs are grouped together phylogenetically. Cis-acting element analysis revealed numerous cis-acting elements associated
