Comprehensive identification and analyses of the Hsf gene family in the whole-genome of three Apiaceae species

Apiaceae is a major family from Apiales and includes many important vegetable medicinal crops. Heat shock transcription factors (Hsf) play roles in heat tolerance during plant development. Here, we conducted systematic analyses of the Hsf gene three species, including 17 Apium graveolens (celery), 32 Coriandrum sativum (coriander), 14 Daucus carota (carrot). A total 73 genes were identified representative Arabidopsis thaliana, Vitis vinifera, Lactuca sativa. Whole-genome duplication played family's expansion within Apiaceae. Interestingly, found that coriander had more than celery carrot due to greater fewer losses. Twenty-seven branches phylogenetic tree underwent considerable positive selection these species. We also explored expression patterns organs. Collectively, this study will serve as rich resource for exploring molecular mechanisms tolerance. Additionally, first report on Apiaceae; thus, our research provide guidance future comparative functional genomic studies others
