Genome-wide identification and expression analysis of trihelix transcription factor family in cucumber (Cucumis sativus L.) and their roles in biotic stress responses

Our study provides the first systematic characterization of the Cucumis sativus L. Trihelix transcription factor family, encompassing genomic, structural, evolutionary, and expression features. The identification of stress-responsive genes (e.g., CsaTri18, SIP1 subfamily) and their associated regulatory networks provides valuable insights into the potential biotic stress defense mechanisms of Cucumis sativus L. These findings lay a foundation for future functional validation of key CsaTri genes and offer potential candidate targets for breeding stress-resistant cucumber varieties.
