摘要： Sweet orange (Citrus sinensis) is the most widely planted and productive citrus fruit, but its growth and yield are susceptible to abiotic and biotic stresses. Heat shock transcription factors (Hsfs) play important roles in regulating plant growth and development and resistance to pests and diseases. However, a systematic study of the CsHsf gene family has not been reported. In this study, we used bioinformatics methods to identify the genome-wide Hsf gene family in sweet orange and then systematically analyzed its gene features, subcellular localization, phylogeny, promoter cis-acting elements, protein interactions, and expression profiles. Seventeen CsHsf gene family members were identified; these genes were randomly distributed on eight chromosomes, and most of the CsHsfs were located in the nucleus. Phylogenetic analyses revealed that CsHsf is closely related to Citrus clementina, and CsHsf can be divided into three clades and 14 subclades. Gene subclades structure and motif analyses supported the results of phylogenetic analyses, and most of the promoter regions of CsHsf gene family members contained cis-responsive elements related to adverse stresses, hormones, and growth and development. GO analyses indicated that the CsHsf gene family plays a role in resistance to environmental stresses and the regulation of metabolism, and the 3D structure revealed a conserved CsHsf protein structure. RNA-Seq data analysis suggested that the CsHsf4 gene has an anti-Penicillium digitatum function. In addition, we first report a new pathway model, including the Ca2+/CaM pathway, the ROS pathway, and the ABA pathway, for the response of the Hsf gene family in sweet orange to abiotic and biotic stresses. This study lays a foundation for abiotic and biotic stress-resistance gene selection and disease-resistance breeding in sweet orange. (c) 2024 SAAB. Published by Elsevier B.V.
