| evolution | 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 | Melaleuca alternifolia |
| 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 | Melaleuca alternifolia |
