Diversity and Functional Evolution of Terpene Synthases in Dictyostelid Social Amoebae.

Dictyostelids, or social amoebae, have a unique life style in forming multicellular fruiting bodies from unicellular amoeboids upon starvation. Recently, dictyostelids were found to contain terpene synthase (TPS) genes, a gene type of secondary metabolism previously known to occur only in plants, fungi and bacteria. Here we report an evolutionary functional study of dictyostelid TPS genes. The number of TPS genes in six species of dictyostelids examined ranges from 1 to 19; and the model species Dictyostelium purpureum contains 12 genes. Using in vitro enzyme assays, the 12 TPS genes from D. purpureum were shown to encode functional enzymes with distinct product profiles. The expression of the 12 TPS genes in D. purpureum is developmentally regulated. During multicellular development, D. purpureum releases a mixture of volatile terpenes dominated by sesquiterpenes that are the in vitro products of a subset of the 12 TPS genes. The quality and quantity of the terpenes released from D. purpureum, however, bear little resemblance to those of D. discoideum, a closely related dictyostelid. Despite these variations, the conserved clade of dictyostelid TPSs, which have an evolutionary distance of more than 600 million years, has the same biochemical function, catalyzing the formation of a sesquiterpene protoillud-7-ene. Taken together, our results indicate that the dynamic evolution of dictyostelid TPS genes includes both purifying selection of an orthologous group and species-specific expansion with functional divergence. Consequently, the terpenes produced by these TPSs most likely have conserved as well as species-adaptive biological functions as chemical languages in dictyostelids. << Less

Tangy scent in Toona sinensis (Meliaceae) leaflets: isolation, functional characterization, and regulation of TsTPS1 and TsTPS2, two key terpene synthase genes in the biosynthesis of the scent compound.

Toona sinensis (Chinese Mahogany; Meliaceae), a subtropical deciduous tree, has a tangy scent resembling a mix of shallots and garlic. T. sinensis has long been known for its medicinal efficacy for treating enteritis, dysentery, itch and some cancers. However, its volatile components and their biosynthesis remain unexamined. In this study, we identified the spectrum of volatile compounds, isolated and functionally characterized two terpene synthase genes, Tstps1 and Tstps2, responsible for terpenoid synthesis in T. sinensis leaflets. TsTPS1 and TsTPS2 afford multiple products upon incubation with geranyl and farnesyl diphosphate respectively and mainly regulate the biosynthesis of (+) limonene and β-elemene in vitro, respectively. Headspace analyses show that 98% of leaflet volatiles were sesquiterpenoids and the developing leaflets released a greater diversity and quantity of volatiles than the mature leaflets did, and that β-elemene was the dominant component in both of them. These data suggested that tangy scent of T. sinensis consists of a combination of terpenoids and that Tstps2 was the major gene involved in the terpenoid biosynthesis in T. sinensis. In situ hybridization revealed that glandular cells of the leaf rachises accumulated abundant Tstps1 mRNA transcripts. Our GFP-based assay further unprecedentedly demonstrated that the transit-peptide of TsTPS1 targets specifically to the mitochondria. << Less
