    3.1.7.11 | physiological function |
both transient and stable overexpression of geranyl(geranyl) diphosphate synthase G(G)PPS and coexpression of G(G)PPS plus geraniol synthase GES significantly enhances the accumulation of secologanin, which in turn elevates the levels of monomeric monoterpene indole alkaloids. Transgenic plants exhibit increased levels of root alkaloid ajmalicine. The dimeric alkaloid vinblastine is enhanced only in G(G)PPS but not in G(G)PPS plus GES transgenic lines |

| 3.1.7.11 | physiological function |
expression of Ocimum basilicum geranyl diposphate synthase in Vitis vinifera, Arabidopsis thaliana, and Nicotiana benthamiana leads to synthesis of geraniol as the main product detected in the leaves, with different minor products citronellol and nerol in Vitis vinifera, linalool and nerol in Nicotiana benthamiana. Engineered Saccharomyces cerevisiae strain A9D expressing Ocimum basilicum geranyl diposphate produces significant quantities of monoterpenes, including 90% geraniol, 5% linalool, 5% citronellol and traces of nerol |

| 3.1.7.11 | physiological function |
feeding of leaves with geraniol, but not tryptophan (precursor fortryptamine), increases the accumulation of the monoterpene indole alkaloids catharanthine and vindoline. Gene silencing significantly reduces the monoterpene indole alkaloid content. Overexpression of GES in leaves increased monoterpene indole alkaloids content. GES exhibits correlation with monoterpene indole alkaloids levels in leaves of different Cataranthus roseus cultivars and has significantly lower expression relative to other pathway genes |

| 3.1.7.11 | physiological function |
overexpression of GES in Nicotiana tabacum. Growth, morphology and photosynthetic efficiency of GES plants are not significantly different from those of control plants. GES plants' direct defenses against herbivores or pathogens are similar to those of control plants, their indirect defense (i.e. attracting herbivore enemy Nesidiocoris tenuis) is stronger compared to that of control plants. GES transgenic plants are susceptible to cold stress and even more susceptible to extreme heat stress (50°C). GES plants show decreased transcription levels of the WRKY33 transcription factor gene and aquaporin gene PIP2 |

transgenic expression in Saccharomyces cerevisiae mutated in the farnesyl diphosphate synthase gene leads to secretion of geraniol into the growth medium |
