Genome‑wide identification and analysis of the trihelix transcription factors in sunflower

The trihelix genes encode plant-specific transcription factors, which play a vital role in plant morphological and developmental processes. However, information about the presence of sunflower (Helianthus annuus L.) is scarce. Sunflower belongs to composite family possesses strong drought salt-alkali tolerance. In this study based on H. genome data, we have identified analyzed with complete description their physical chemical properties, phylogenetic relationships, motif composition, chromosome distribution, exon-intron structure, cis-acting elements, collinearity. annuus, 31 full-length were categorized into six subgroups (SIP, GT1, SH4, Gδ, GT-γ, GT2). Multiple Em for elicitation (MEME), used conservative analysis, 10 distinct motifs unevenly distributed genes. addition that, localization analysis showed number distribution these 17 chromosomes annuus. Transcriptional structure revealed introns exons different gene members. Furthermore, cis-element 19 types cis-elements mainly related abiotic stress, hormones, growth development plant. Results manifested novel insights relationships possible functions Moreover, findings can assist future studies regarding specific physiological effects factors.
