As an organelle only found in plant cells and some protists, the chloroplast is not only the main metabolic energy originator, but also the abiotic/biotic stress sensor and defense signal generator. For a long time, chloroplasts have been recognized as a common target by many plant viruses. Viruses may directly modify chloroplast membranes to assemble their replication complex for viral genome replication. Viruses may downregulate chloroplast-related and photosynthesis-related genes via an as yet unknown mechanism to support their infection. Viruses may also interrupt functionality of the photosynthetic machinery through protein-protein interactions. This review briefly summarizes current knowledge about modifications of the photosynthetic machinery by plant viruses, highlights the important role of chloroplasts in the infection process and discusses chloroplast-associated pathogenesis.
叶绿体作为一种仅存在于植物细胞和某些原生生物中的细胞器，不仅是主要的代谢能量起源者，也是非生物/生物胁迫传感器和防御信号发生器。长期以来，叶绿体一直被认为是许多植物病毒的共同靶标。病毒可能直接修饰叶绿体膜以组装其复制复合体用于病毒基因组复制。病毒可能通过一种尚不清楚的机制下调叶绿体相关和光合作用相关基因以支持其感染。病毒还可能通过蛋白质-蛋白质相互作用中断光合机构的功能。本文综述简要总结了目前关于植物病毒对光合机构修饰的知识，强调了叶绿体在感染过程中的重要作用，并讨论了与叶绿体相关的发病机制。
