Plant specialized metabolites are often synthesized and stored in dedicated morphological structures such as glandular trichomes, resin ducts, or laticifers where they accumulate in large concentrations. How this high productivity is achieved is still elusive, in particular, with respect to the interface between primary and specialized metabolism. Here, we focus on glandular trichomes to survey recent progress in understanding how plant metabolic cell factories manage to balance homeostasis of essential central metabolites while producing large quantities of compounds that constitute a metabolic sink. In particular, we review the role of gene duplications, transcription factors and photosynthesis.
植物特化代谢产物通常在特定的形态结构中合成和储存，如腺毛、树脂道或乳汁管，它们在这些结构中大量积累。目前仍不清楚这种高产量是如何实现的，特别是在初级代谢和特化代谢的界面方面。在这里，我们聚焦于腺毛，以综述近期在理解植物代谢细胞工厂如何在产生大量构成代谢库的化合物的同时，平衡必需中心代谢物的稳态方面所取得的进展。特别是，我们回顾了基因复制、转录因子和光合作用的作用。
