All plants synthesize a diverse array of terpenoid metabolites. Some are common to all, but many are synthesized only in specific taxa and presumably evolved as adaptations to specific ecological conditions. While the basic terpenoid biosynthetic pathways are common in all plants, recent discoveries have revealed many variations in the way plants synthesized specific terpenes. A major theme is the much greater number of substrates that can be used by enzymes belonging to the terpene synthase (TPS) family. Other recent discoveries include non-TPS enzymes that catalyze the formation of terpenes, and novel transport mechanisms.

越多越好：植物中萜烯代谢的多样性。

所有植物都合成各种各样的萜类代谢产物。有些是所有人共有的，但许多仅在特定的分类单元中合成，并且可能是根据特定的生态条件而演变而来的。虽然基本的萜类生物合成途径在所有植物中都很普遍，但最近的发现揭示了植物合成特定萜烯的方式有许多变化。一个主要主题是属于萜烯合酶（TPS）家族的酶可以使用的底物数量更多。最近的其他发现包括催化萜烯形成的非TPS酶，以及新颖的转运机制。
