Background  Crop quality and yield are affected by abiotic and biotic stresses, and heat shock transcription factors ( Hsfs ) are considered to play important roles in regulating plant tolerance under various stresses. To investigate the response of  Cucurbita moschata  to abiotic stress, we analyzed the genome of  C. moschata .    Results  In this research, a total of 36  C. moschata Hsf  ( CmHsf ) members were identified and classified into three subfamilies (I, II, and III) according to their amino acid sequence identity. The  Hsfs  of the same subfamily usually exhibit a similar gene structure (intron-exon distribution) and conserved domains (DNA-binding and other functional domains). Chromosome localization analysis showed that the 36  CmHsfs  were unevenly distributed on 18 of the 21 chromosomes (except for Cm_Chr00, Cm_Chr08 and Cm_Chr20), among which 18 genes formed 9 duplicated gene pairs that have undergone segmental duplication events. The Ka/Ks ratio showed that the duplicated  CmHsfs  have mainly experienced strong purifying selection. High-level synteny was observed between  C. moschata  and other  Cucurbitaceae  species .Conclusions  The expression profile of  CmHsfs  in the roots, stems, cotyledons and true leaves revealed that the  CmHsfs  exhibit tissue specificity. The analysis of  cis -acting elements and quantitative real-time polymerase chain reaction (qRT-PCR) revealed that some key  CmHsfs  were activated by cold stress, heat stress, hormones and salicylic acid. This study lays the foundation for revealing the role of  CmHsfs  in resistance to various stresses, which is of great significance for the selection of stress-tolerant  C. moschata .
