The tomato cis-prenyltransferase gene family.
Akhtar T.A., Matsuba Y., Schauvinhold I., Yu G., Lees H.A., Klein S.E., Pichersky E.
cis-prenyltransferases (CPTs) are predicted to be involved in the synthesis of long-chain polyisoprenoids, all with five or more isoprene (C5) units. Recently, we identified a short-chain CPT, neryl diphosphate synthase (NDPS1), in tomato (Solanum lycopersicum). Here, we searched the tomato genome ... >> More
cis-prenyltransferases (CPTs) are predicted to be involved in the synthesis of long-chain polyisoprenoids, all with five or more isoprene (C5) units. Recently, we identified a short-chain CPT, neryl diphosphate synthase (NDPS1), in tomato (Solanum lycopersicum). Here, we searched the tomato genome and identified and characterized its entire CPT gene family, which comprises seven members (SlCPT1-7, with NDPS1 designated as SlCPT1). Six of the SlCPT genes encode proteins with N-terminal targeting sequences, which, when fused to GFP, mediated GFP transport to the plastids of Arabidopsis protoplasts. The SlCPT3-GFP fusion protein was localized to the cytosol. Enzymatic characterization of recombinant SlCPT proteins demonstrated that SlCPT6 produces Z,Z-FPP, and SlCPT2 catalyzes the formation of nerylneryl diphosphate while SlCPT4, SlCPT5 and SlCPT7 synthesize longer-chain products (C25-C55). Although no in vitro activity was demonstrated for SlCPT3, its expression in the Saccharomyces cerevisiae dolichol biosynthesis mutant (rer2) complemented the temperature-sensitive growth defect. Transcripts of SlCPT2, SlCPT4, SlCPT5 and SlCPT7 are present at low levels in multiple tissues, SlCPT6 is exclusively expressed in red fruit and roots, and SlCPT1, SlCPT3 and SlCPT7 are highly expressed in trichomes. RNAi-mediated suppression of NDPS1 led to a large decrease in β-phellandrene (which is produced from neryl diphosphate), with greater reductions achieved with the general 35S promoter compared to the trichome-specific MKS1 promoter. Phylogenetic analysis revealed CPT gene families in both eudicots and monocots, and showed that all the short-chain CPT genes from tomato (SlCPT1, SlCPT2 and SlCPT6) are closely linked to terpene synthase gene clusters. << Less

Biosynthesis of the diterpenoid lycosantalonol via nerylneryl diphosphate in Solanum lycopersicum.
Matsuba Y., Zi J., Jones A.D., Peters R.J., Pichersky E.
We recently reported that three genes involved in the biosynthesis of monoterpenes in trichomes, a cis-prenyltransferase named neryl diphosphate synthase 1 (NDPS1) and two terpene synthases (TPS19 and TPS20), are present in close proximity to each other at the tip of chromosome 8 in the genome of ... >> More
We recently reported that three genes involved in the biosynthesis of monoterpenes in trichomes, a cis-prenyltransferase named neryl diphosphate synthase 1 (NDPS1) and two terpene synthases (TPS19 and TPS20), are present in close proximity to each other at the tip of chromosome 8 in the genome of the cultivated tomato (Solanum lycopersicum). This terpene gene "cluster" also contains a second cis-prenyltransferase gene (CPT2), three other TPS genes, including TPS21, and the cytochrome P450-oxidoreductase gene CYP71BN1. CPT2 encodes a neryneryl diphosphate synthase. Co-expression in E. coli of CPT2 and TPS21 led to the formation of the diterpene lycosantalene, and co-expression in E. coli of CPT2, TPS21 and CYP71BN1 led to the formation of lycosantalonol, an oxidation product of lycosantalene. Here we show that maximal expression of all three genes occurs in the petiolule part of the leaf, but little expression of these genes occurs in the trichomes present on the petiolules. While lycosantalene or lycosantalonol cannot be detected in the petiolules of wild-type plants (or anywhere else in the plant), lycosantalene and lycosantalonol are detected in petiolules of transgenic tomato plants expressing CPT2 under the control of the 35S CaMV promoter. These results suggest that lycosantalene and lycosantalonol are produced in the petiolules and perhaps in other tissues of wild-type plants, but that low rate of synthesis, controlled by the rate-limiting enzyme CPT2, results in product levels that are too low for detection under our current methodology. It is also possible that these compounds are further modified in the plant. The involvement of CPT2, TPS21 and CYP71BN1 in a diterpenoid biosynthetic pathway outside the trichomes, together with the involvement of other genes in the cluster in the synthesis of monoterpenes in trichomes, indicates that this cluster is further evolving into "sub-clusters" with unique biochemical, and likely physiological, roles. << Less
