A heat shock protein gene，naming CmHSP70-5，was isolated from pumpkin cDNA by
polymerase chain reaction （PCR） method based on pumpkin genome sequence．Phylogenetic relationship
of HSP70-5 and its homology were analyzed using bioinformation method．The expression quantity of CmHSP70-5 under heat stress was studied by real-time PCR．The results showed that CmHSP70-5 gene was 1
953 bp，and its coding CmHSP70-5 protein had the closest relative with Arabidopsis AtHSP70-5．CmHSP70-5
gene had a high expression level in roots than in stems and leaves under normal conditions．Real-time PCR
results indicated that under heat stress，the expression of CmHSP70-5 gene in roots，stems and leaves were all
up-regulated and could reach the maximum quantity 3 hours after treatment，indicating that the expression of CmHSP70-5 gene was related to heat stress in Cucurbita moschata．
