title: Unusual intron in the second exon of a Type III polyketide synthase gene of Alpinia calcarata Rosc.
abstract: Plant phenolic compounds form a valuable resource of secondary metabolites having a broad spectrum of biological activities. Type III polyketide synthases play a key role in the formation of basic structural skeleton of the phenolic compounds. As a group of medicinal plants, PKSs with novel features are expected in the genome of Zingiberaceae. The genomic exploration of PKS in Alpinia calcarata conducted in this study identified the presence of an unusual intron at the region forming the second exon of typical PKSs, forming a gateway information of distribution of novel PKSs in Zingiberaceae.
