| contents | Genome-Wide Analysis of Heat Shock Transcription Factors (HSFs) in Kelp () and Analysis of Their Expression in Response to Abiotic Stresses. Mao, Wentai Zhu, Wenbo Li, Ruixue Lu, Jianjun Han, Yijuan Tang, Weiqi Lin, Hongmei Wang, Wenshan Chen, Xiaoting Chen, Songbiao Lin, Wenwei Lin, Zhongyuan Heat shock transcription factors (HSFs) play a crucial role in mediating responses to abiotic stresses. However, characterization of HSFs in macroalgae remains largely unexplored. In this study, a comprehensive analysis of HSFs was carried out in . A total of sixteen were identified. Phylogenetic analysis revealed that HSFs from brown algae form a distinct clade, separate from those from red algae, green algae, moss, and . The DNA-binding domain was found to be highly conserved among SjHSFs. Analysis of cis-acting elements in promoters suggested their potential roles in regulating growth, development, and stress responses. Tissue-specific expression profiles revealed differential expression of across various tissues of . Under abiotic stresses, certain exhibited dynamic expression patterns, with particularly pronounced changes observed under high-temperature stress. We further employed a transcription factor-centered yeast one-hybrid (TF-Centered Y1H) to determine the motifs recognized by SjHSF-03. Seven conserved motifs were identified, and the distributions of these motifs were screened in the promoter regions of genes involved in diverse biological processes and pathways. Notably, 23 heat shock protein () genes were among these motif-containing genes, and 21 out of these 23 were up-regulated under heat stress. Our results provide a solid foundation for future research on the specific functions of HSFs under different stress conditions and the regulatory mechanisms of HSF-mediated stress responses in and other brown algae. |
