Plants have a remarkable capacity for the production of a wide range of metabolites. Much has been reported and reviewed on the diversity of these metabolites and how it is achieved, for example through the evolution of enzyme families. In comparison, relatively little is known on the extraordinary metabolic productivity of dedicated organs where many of these metabolites are synthesized and accumulate. Plant glandular trichomes are such specialized metabolite factories, for which recent omics analyses have shed new light on the adaptive metabolic strategies that support high metabolic fluxes. In photosynthetic trichomes such as those of the Solanaceae, these include CO refixation and possibly C4-like metabolism which contribute to the high productivity of these sink organs.
植物具有生产广泛代谢物的惊人能力。已经有大量关于这些代谢物的多样性以及如何实现多样性的报道和综述，例如通过酶家族的进化。相比之下，对于专门的器官（许多代谢物在这些器官中合成和积累）的非凡代谢生产力，人们知之甚少。植物腺毛是这种专门的代谢产物工厂，最近的组学分析揭示了支持高代谢通量的适应性代谢策略。在光合作用的毛状体中，如茄科的毛状体，包括 CO 再固定和可能的 C4 样代谢，这有助于这些汇器官的高生产力。
