Abstract: A TPS gene named as Hc-Sesqui was isolated from H.coronarium leaf. The complete sequence of the cDNA gene was 1 932 bp, with an ORF encoding 551 amino acids. The amino acids sequence shared highly homology to other sesquiterpenoid synthase, containing conserved boxes of: TPS DDXXD. The phylogenetic analysis after Clustal.X alignment suggested that the Hc-Sesqui belonged to Tps-a. Northern blot revealed that the Hc-Sesqui gene was expressed in leaf, stem and sepal.

Key words: Hedychium coronarium Koenig, sesquiterpenoid synthase, gene cloning, expression
