4.2.3.120 | physiological function |
AvPS (AvTPS1) is not responsible for pinene biosynthesis in the seeds of Amomum villosum, no expression of this gene is detected in the seeds, and the expression of AvPS is not in accordance with the accumulation pattern of pinene in the leaves. But alpha-pinene is widely distributed throughout almost the whole plant, i.e. roots, creeping stems, leaves, pericarp, and seeds. beta-Pinene is found in all the tissues, except seeds. Pinene is a naturally occurring constituent of the essential oils in many plant species that has a relevant role in insect repellency and allelopathy (inhibiting root growth of the tested weed species). Gene AvPS is highly expressed in pericarp, the exterior tissue protecting the fruits against biotic stress, AvPS might be the gene involved in biotic defense in Amonum villosum |

4.2.3.120 | physiological function |
in isoform TPS3-silenced plants, alpha-pinene, beta-pinene and beta-phellandrene contents decrease by more than 80%, whereas beta-myrcene is unchanged |

4.2.3.120 | physiological function |
mutationally converting S-limonene synthase from Mentha spicata (UniProt ID Q9SW76, EC 4.2.3.16) to beta-pinene synthase (EC 4.2.3.122 and 4.2.3.120) or phellandrene synthase (EC 4.2.3.51) reveals the plasticity of the active site |
