Abstract: The techniques of homology cloning and anchored PCR were used to clone the Hsp90 gene from black tiger shrimp. The full length cDNA of black tiger shrimp Hsp90 (btsHsp90) contained a 5鈥?untranslated region (UTR) of 72 bp, an ORF (open reading frame) of 2160 bp encoding a polypeptide of 720 amino acids with an estimated molecular mass of 83-kDa and a 3鈥?UTR of 288 bp. The sequence of the coding region showed 90 and 84% homology with that of the Chiromantes haematocheir and Homo sapiens, respectively. Conserved signature sequences of Hsp90 gene family were found in the btsHsp90 deduced amino acid sequence. The temporal expressions of Hsp90 gene were constitutively in the black tiger shrimp tissues including liver, ovary, muscle, brain stomach, and heart, and their levels were markedly enhanced after 30-min heat treatment at 37擄C. In ovarian maturation stages, the expression of btsHsp90 was strongest in the second stage, weaker in the fourth and first stage.
