Abstract Abstract Cucurbita ficifolia is one of characteristic germplasm crops that has strong resistance abilities to many disease pathogens stress, especially resistance to Fusarium oxysporum. Based on the degenerated primers being designed according to the conserved regions of NBS type genes in other plants, eight RGA sequences were cloned and sequenced from Cucurbita ficifolia genome by PCR amplification. Among them, the sequence of HQRGA2 had got NB-ARC structure domain and would be classified an individual category, yet the other seven sequences hadn’t got the NBS domains by multi alignment sequence contrast. Furthermore, the results of nucleotide homology analysis indicated that 98% and 97% of nucleotides of HQRGA2 were identity to the resistant genes SQRGA-13 and SQRGA-8 from Cucurbita moschata respectively. Furthermore, the amino acid sequence analysis results showed that the sequence of HQRGA2 belonged to the class of Non-TIR-NBS-LRR disease-resistance genes analogues, which contains the conserved regions of P-loop, Kinase-2, Kinase-3, and GLPL domain. We also obtained that 96.6% amino acids were homology to RGAs of Cucurbita moschata by comparison analysis of amino acid sequences. The results of qRT- PCR showed that the expression of HQRGA2 from C. ficifolia was influenced and induced by the fungi of Fusarium oxysporum, with the expression pattern of ‘up-down’, which indicated its relation to resistance gene in the aspect. The obtaining of NBS type of R-gene analogues provided us a clue for the further cloning of disease- resistance genes from Cucurbita ficifolia., Abstract Cucurbita ficifolia is one of characteristic germplasm crops that has strong resistance abilities to many disease pathogens stress, especially resistance to Fusarium oxysporum.
