      InDrosophila

      , heat shock protein 27 (Hsp27) is a critical single-copy intron-free nuclear gene involved in the defense responseagainst fungi and bacteria, and is a regulator of adult lifespan. In the present study, 33 homologousHsp27nucleotide sequencesfrom differentDrosophilaspecies were amplified by PCR and reverse transcription PCR, and the phylogenetic relationshipswere analysed using neighbour-joining, maximum-likelihood and Bayesian methods. The phylogenetic topologies from anal-ysis with different algorithms were similar, suggesting that theHsp27gene was split by a recently acquired intron during theevolution of theDrosophila ananassaesubgroup
