Plastids are organelles delineated by two envelopes playing important roles in different cellular processes such as energy production or lipid biosynthesis. To regulate their biogenesis and their function, plastids have to communicate with other cellular compartments. This communication can be mediated by metabolites, signaling molecules, and by the establishment of direct contacts between the plastid envelope and other organelles such as the endoplasmic reticulum, mitochondria, peroxisomes, plasma membrane, and the nucleus. These interactions are highly dynamic and respond to different biotic and abiotic stresses. However, the mechanisms involved in the formation of plastid-organelle contact sites and their functions are still far from being understood. In this chapter, we summarize our current knowledge about plastid contact sites and their role in the regulation of plastid biogenesis and function.
质体是由双层膜界定的细胞器，在能量产生或脂质生物合成等不同的细胞过程中发挥重要作用。为了调节其生物发生和功能，质体必须与其他细胞区室进行通信。这种通信可以通过代谢物、信号分子以及通过质体膜与其他细胞器（如内质网、线粒体、过氧化物酶体、质膜和细胞核）之间的直接接触来介导。这些相互作用是高度动态的，并对不同的生物和非生物胁迫作出响应。然而，形成质体-细胞器接触位点的机制及其功能仍然远未被理解。在本章中，我们总结了我们目前对质体接触位点及其在调节质体生物发生和功能中的作用的认识。
