Genome-Wide Analysis of <i>Tritipyrum HSFs</i> and Functional Characterization of <i>TtHSF97</i> for Salt Tolerance.

ABSTRACT: Soil salinization is a major abiotic stress constraining global agricultural production. In this study, a genome-wide analysis of the salt-tolerant hybrid germplasm Tritipyrum identified 103 heat shock transcription factors (TtHSF) genes, which were classified into three major groups (A, B, and C) and shared conserved motifs. Transcriptome data and qRT-PCR revealed that 29 of the TtHSF genes exhibited high expression levels in response to salt stress and recovery. Notably, TtHSF97, localized on Tel5E01T611500, exhibited significantly upregulated expression under salt stress. Subcellular localization confirmed that TtHSF97 is a nuclear-enriched protein, consistent with its function as a transcription factor. Heterologous overexpression of TtHSF97 in Ara
