Actinidia chinensis terpene synthase1 (AcTPS1) is identified as part of an array of eight tandemly duplicated genes. Actinidia arguta AaTPS1 and Actinidia chinensis AcTPS1 likely originate from a common ancestral gene, phylogenetic analysis of the AaTPS1 and AcTPS1 |

transcriptome analysis of the 3 cardinal terpene chemotypes of Melaleuca alternifolia in young leaves, mature leaves, and stem and compared transcript abundance to variation in the constitutive profile of terpenes. The three cardinal chemotypes are dominated by terpinen-4-ol, terpinolene or 1,8-cineole and their biosynthetically related compounds. Chemotype 2 plants (dominated by terpinolene) show a greater degree of differential gene expression compared to the other chemotypes, which might be related to the isolation of plant populations that exhibit this chemotype and the possibility that the terpinolene synthase gene in Melaleuca alternifolia is derived by introgression from a closely related species, Melaleuca trichostachya, multivariate analyses, overview |

| 4.2.3.113 | malfunction |
transcription factors AaNAC2, AaNAC3, and AaNAC4 bind a 28-bp fragment of the proximal NAC binding site in the Actinidia arguta TPS1 promoter but not the Actinidia chinensis AcTPS1 promoter, where the NAC binding site is mutated. Activation can be restored by reintroducing multiple repeats of the 12-bp NAC core-binding motif. The absence of NAC transcriptional activation in ripe Actinidia chinensis fruit can account for the low accumulation of AcTPS1 transcript, protein, and monoterpene volatiles in this species |

| 4.2.3.113 | physiological function |
high rates of terpinolene production in ripe Actinidia arguta fruit are correlated with increasing gene and protein expression of Actinidia arguta terpene synthase1 (AaTPS1) and correlates with an increase in transcript levels of the 2-C-methyl-D-erythritol 4-phosphate pathway enzyme 1-deoxy-D-xylulose-5-phosphate synthase (DXS). DXS is likely to be the key step in regulating 2-C-methyl-D-erythritol 4-phosphate substrate flux in kiwifruit. Transcription factors AaNAC2, AaNAC3, and AaNAC4 bind a 28-bp fragment of the proximal NAC binding site in the AaTPS1 promoter but not the Actinidia chinensis AcTPS1 promoter, where the NAC binding site is mutated. Importance of NAC transcription factors in controlling monoterpene production and other traits in ripening fruits. Ripe fruits of Actinidia arguta have a very high amount of terpene volatiles released as compared to other Actinidia species fruits, overview |

| 4.2.3.113 | physiological function |
quantitative terpene variation is highly influenced by the combined expression of genes in the methylerythritol 4-phosphate (MEP) pathway, all tissues from chemotype 2 plants contain more terpinolene and 1,8-cineole, very low contents in chemotype 1, and no terpinolene in chemotype 3, determination of total terpene concentration for the three cardinal chemotypes in Melaleuca alternifolia, overview. Emissions from the plants are dominated by the following compounds: chemotype 1 by p-cymene and gamma-terpinene with terpinene-4-ol being the third most abundant compound, chemotype 2 by p-cymene, terpinolene, alpha-pinene, limonene and 1,8-cineole, and chemotype 5 by 1,8-cineole, alpha-pinene and limonene |
