In many plants belonging to angiosperms and gymnosperms the accumulation in leaves of long chain polyprenols and polyprenyl esters during growth in natural habitats depends on the light intensity. The amount of polyprenols in leaves is also positively correlated with the thickness of the leaf blade (SLA, specific leaf area). The polyprenol content of leaves shows seasonal changes with a maximum in autumn and a minimum in early summer with the difference between poorly and well illuminated plants persisting throughout the vegetation season.

    • "Despite the widespread occurrence of medium-chain products (C25–C65) such as those synthesized by SlCPT4, 5 and 7, their functional significance remains unclear. Medium-and long-chain polyisoprenoids are known to accumulate in senescing photosynthetic tissues, and their synthesis is stimulated by light (Chojnacki and Vogtman, 1984; Bajda et al., 2005). Indirect evidence for the association of polyisoprenoids with plant cell walls comes from a recently characterized group of saprophytic bacteria that possess a unique polyisoprenoid-binding protein that aids in the dismantling of plant cell-wall material (Vincent et al., 2010).

    ABSTRACT: cis-Prenyltransferases (CPTs) are predicted to be involved in the synthesis of long-chain polyisoprenoids, all with >5 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 is composed of seven members (SlCPT1-7, with NDPS1 designated as SlCPT1). Six SlCPT genes encode proteins with N-terminal targeting sequences, which, when fused to the green fluorescent protein (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). While no in vitro activity could be 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. RNA interference-mediated suppression of NDPS1 led to a large decrease in β-phellandrene (which is made 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 that all the short-chain CPTs from tomato (SlCPT1, SlCPT2, and SlCPT6) are closely linked to terpene synthase gene clusters. © 2012 The Authors.

    • "The collection was performed in October and November of 2003 during the end of a vegetation period of leaves. About 20 of them were performed in duplicate to exclude the possibility of the effect of insolation on the rate of accumulation of polyprenols (Bajda et al., 2005). "

    ABSTRACT: The occurrence of polyprenols in leaves of over 340 species of dendroflora in natural habitats in the regions of Hanoi and Hue in Vietnam was studied. Plant material was collected in the late autumn (October/November) during the end of a vegetation season. Leaves of about 200 plant species did not contain detectable amounts of polyprenols in contrast to few systematic families, e.g. Moraceae, Euphorbiaceae, where polyprenols were highly abundant and their pattern could be used as a chemotaxonomic criterion. Most often dominating polyprenols were prenol-11 and prenol-12. In several angiosperm species prenol-13 and detectable amounts of prenol-14 were also found. The incidence of prenol-13 and -14 was not restricted to a specific taxonomic group since species exhibiting domination of such longer chain polyprenols belonged to various systematic families. In some plants (e.g. Ceiba pentandra) alpha-cis polyprenols were accompanied by alpha-trans counterparts. This report describes several new plant species that may serve as natural sources of long chain polyprenols.

    ABSTRACT: The polyisoprenoid alcohols and their derivatives are highlighted here. These linear polymers of isoprenoid residues are widespread in nature from bacteria to human cells. This review presents their structures, distribution and biogenesis. Attention will be focused on the biosynthesis of polyisoprenoid alcohols in plants in the context of two coexisting isoprenoid pathways, mevalonate and the recently described methylerythritol phosphate pathway. Structural aspects including modeling of the polyisoprenoid conformation will be presented and finally the postulated biological role of polyisoprenoid alcohols will be discussed including polyisoprenylation of proteins.
