Plant specialized metabolism has a complex evolutionary history. Some aspects are conserved across the green lineage, but many metabolites are unique to certain lineages. The network of specialized metabolism continuously diversified, simplified or reshaped during the evolution of streptophytes. Many routes of pan-plant specialized metabolism are involved in plant defence. Biotic interactions are recalled as major drivers of lineage-specific metabolomic diversification. However, the consequences of this diversity of specialized metabolism in the context of plant terrestrialization and land plant diversification into the major lineages of bryophytes, lycophytes, ferns, gymnosperms and angiosperms remain only little explored. Overall, this hampers conclusions on the evolutionary scenarios that shaped specialized metabolism. Recent efforts have brought forth new streptophyte model systems, an increase in genetically accessible species from distinct major plant lineages, and new functional data from a diversity of land plants on specialized metabolic pathways. In this review, we will integrate the recent data on the evolution of the plant immune system with the molecular data of specialized metabolism and its recognition. Based on this we will provide a contextual framework of the pan-plant specialized metabolism, the evolutionary aspects that shape it and the impact on adaptation to the terrestrial environment.This article is part of the theme issue 'The evolution of plant metabolism'.
植物的特化代谢具有复杂的进化历史。有些方面在绿藻谱系中是保守的，但许多代谢物是某些谱系所特有的。在石松类植物的进化过程中，特化代谢网络不断多样化、简化或重塑。许多泛植物特化代谢途径参与植物防御。生物相互作用被认为是谱系特化代谢多样化的主要驱动因素。然而，在植物向陆地化和陆地植物向苔藓植物、石松植物、蕨类植物、裸子植物和被子植物等主要谱系多样化的背景下，这种特化代谢多样性的后果仍知之甚少。总的来说，这阻碍了对塑造特化代谢的进化情景的结论。最近的努力带来了新的石松类模型系统，来自不同主要植物谱系的可遗传物种的增加，以及来自多种陆地植物的特化代谢途径的新功能数据。在这篇综述中，我们将整合植物免疫系统进化的最新数据与特化代谢及其识别的分子数据。在此基础上，我们将为泛植物特化代谢提供一个上下文框架，以及塑造它的进化方面及其对适应陆地环境的影响。本文是主题为“植物代谢进化”的特刊的一部分。
