Expression Analysis of Trihelix Transcription Factor Family in Strawberries and Functional Characterization of FvTrihelix6

The Trihelix is a plant-specific transcription factor family and has critical roles in plant growth development stress resistance. There less information about genes their potential functions strawberries (Fragaria vesca). In the present study, we performed detailed bioinformatics analysis of including physicochemical properties, chromosomal location, exon–intron distribution, domain arrangement, subcellular localization. Thirty members were identified divided into five subfamilies. expression FvTrihelix different tissues/organs, i.e., root, stolon, leaf, flower, fruit, was measured after infection with Colletotrichum. gloeosporioides foliar applications salicylic acid (SA) jasmonic (JA). Most showed differential responses following C. hormone treatments (SA JA), suggesting disease resistance hormonal signaling pathways. As anticipated, ectopic FvTrihelix6 Arabidopsis thaliana increased against higginsianum infection. protein localized nucleus. We surmise that enhances pathogens through SA JA This study provides novel insights strawberry new candidates for disease-resistance breeding strawberries.
