酚类蔗糖酯（pse）是一组不同的特化代谢物，存在于几种被子植物谱系中。系统发育重建和结构变化表明，这些代谢物可能在单子叶和双子叶中独立进化。PSE丰度在植物各器官和发育阶段的组成差异与上游苯丙氨酸途径的转录调控有关，而病原体诱导则由与胁迫相关的植物激素（如乙烯）调控。pse具有共同的结构特征，表明它们的生物合成可能涉及一种或多种羟基肉桂基转移酶和BAHD乙酰转移酶，这可以通过多组学数据集的相关分析来确定。阐明这些化合物的核心生物合成途径对于更详细地研究这些化合物的生物学功能及其潜在的药用和农业应用至关重要。
Phenolic sucrose esters (PSEs) are a diverse group of specialized metabolites that are present in several angiosperm lineages. Phylogenetic reconstruction and structural variation suggest that these metabolites may have evolved independently in monocots and dicots. Constitutive variation in PSE abundance across plant organs and developmental stages is correlated with transcriptional regulation of the upstream phenylpropanoid pathway, whereas pathogen induction is regulated by stress-related phytohormones such as ethylene. Shared structural features of PSEs indicate that their biosynthesis may involve one or more hydroxycinnamoyl transferases and BAHD acetyltransferases, which could be identified by correlative analyses of multi-omics datasets. Elucidation of the core biosynthetic pathway of PSEs will be essential for more detailed studies of the biological function of these compounds and their potential medicinal and agricultural applications.
