The sequestration of enzymes and associated processes into sub-cellular domains, called organelles, is considered a defining feature of eukaryotic cells. However, what leads to specific outcomes and allows a eukaryotic cell to function singularly is the interactivity and exchanges between discrete organelles. Our ability to observe and assess sub-cellular interactions in living plant cells has expanded greatly following the creation of fluorescent fusion proteins targeted to different organelles. Notably, organelle interactivity changes quickly in response to stress and reverts to a normal less interactive state as homeostasis is re-established. Using key observations of some of the organelles present in a plant cell, this chapter provides a brief overview of our present understanding of organelle interactions in plant cells.
将酶和相关过程隔离到称为细胞器的亚细胞结构域中，被认为是真核细胞的一个重要特征。然而，使真核细胞具有独特功能的是离散细胞器之间的相互作用和物质交换。通过创建靶向不同细胞器的荧光融合蛋白，我们能够极大地观察和评估活植物细胞中的亚细胞相互作用。值得注意的是，细胞器的相互作用会迅速响应压力而发生变化，并在建立新的平衡状态时恢复到正常的相互作用程度较低的状态。本文利用植物细胞中存在的一些细胞器的关键观察结果，简要概述了我们目前对植物细胞中细胞器相互作用的理解。
