质体是植物细胞中重要的细胞器，具有多种功能，是许多代谢途径的核心。除了它们在初级代谢中的主要作用之外，它们在光合作用中的作用可能是最为人所知的，质体有助于植物激素和其他次级代谢物的生物合成，储存重要的生物分子，并感受一系列环境压力。因此，质体来源的信号通常通过发射调节核基因表达的信号分子来协调许多生理和发育过程。最近的一些优秀的评论提供了广泛的观点质体信号通路。在这篇综述中，我们将强调我们的叶绿体信号通路的理解的最新进展。我们的讨论集中在阐明叶绿体如何决定细胞中的生死决定的新发现和阐明四吡咯生物合成信号转导网络的研究。我们还将研究质体RNA解旋酶，ISE2，在叶绿体信号的作用，并仔细研究有趣的结果调查的潜在作用，在进行信号从叶绿体到其他细胞位置的基质。
Plastids are critical organelles in plant cells that perform diverse functions and are central to many metabolic pathways. Beyond their major roles in primary metabolism, of which their role in photosynthesis is perhaps best known, plastids contribute to the biosynthesis of phytohormones and other secondary metabolites, store critical biomolecules, and sense a range of environmental stresses. Accordingly, plastid-derived signals coordinate a host of physiological and developmental processes, often by emitting signalling molecules that regulate the expression of nuclear genes. Several excellent recent reviews have provided broad perspectives on plastid signalling pathways. In this review, we will highlight recent advances in our understanding of chloroplast signalling pathways. Our discussion focuses on new discoveries illuminating how chloroplasts determine life and death decisions in cells and on studies elucidating tetrapyrrole biosynthesis signal transduction networks. We will also examine the role of a plastid RNA helicase, ISE2, in chloroplast signalling, and scrutinize intriguing results investigating the potential role of stromules in conducting signals from the chloroplast to other cellular locations.
