Cloning of the heat shock protein 60 gene from the stem borer, Chilo suppressalis, and analysis of expression characteristics under heat stress.

ABSTRACT: Heat shock protein 60 is an important chaperonin. In this paper, hsp60 of the stem borer, Chilo suppressalis (Walker) (Lepidoptera: Pyralidae), was cloned by RT-PCR and rapid amplification of cDNA end (RACE) reactions. The full length cDNA of hsp6 degrees Consisted of 2142 bp, with an ORF of 1719 bp, encoding 572 amino acid residues, with a 5'UTR of 158 bp and a 3'UTR of 265 bp. Cluster analysis confirmed that the deduced amino acid sequence shared high identity with the reported sequences from other insects (77%-86%). To investigate whether hsp60 in C. suppressalis responds to thermal stress, the expression levels of hsp60 mRNA in larval haemocytes across temperature gradients from 31 to 39 degrees C were analysed by real-time quantitative PCR. There was no significant difference for hsp6
