Plant viruses are responsible for losses in worldwide production of numerous economically important food and fuel crops. As obligate cellular parasites with very small genomes, viruses rely on their hosts for replication, assembly, intra- and intercellular movement, and attraction of vectors for dispersal. Chloroplasts are photosynthesis and are the site of replication for several viruses. When viruses replicate in chloroplasts, photosynthesis, an essential process in plant physiology, is inhibited. The mechanisms underlying molecular and biochemical changes during compatible and incompatible plants–virus interactions, are only beginning to be elucidated, including changes in proteomic profiles induced by virus infections. In this review, we highlight the importance of proteomic studies to understand plant–virus interactions, especially emphasizing the changes in photosynthesis-related protein accumulation. We focus on: (a) chloroplast proteins that differentially accumulate during viral infection; (b) the significance with respect to chloroplast-virus interaction; and (c) alterations in plant’s energetic metabolism and the subsequently the plant defense mechanisms to overcome viral infection.

哪些蛋白质组学可以揭示植物与病毒的相互作用?与光合作用相关的蛋白质成为人们关注的焦点。

植物病毒是造成全球许多具有重要经济意义的粮食和燃料作物生产损失的原因。作为具有很小基因组的专性细胞寄生虫,病毒依靠其宿主进行复制,组装,细胞内和细胞间移动以及吸引载体进行分散。叶绿体是光合作用,是几种病毒的复制位点。当病毒在叶绿体中复制时,光合作用是植物生理学中必不可少的过程。在兼容和不兼容的植物与病毒相互作用过程中,分子和生化变化的潜在机制才刚刚被阐明,包括由病毒感染引起的蛋白质组学变化。在这篇评论中,我们强调了蛋白质组学研究对理解植物与病毒相互作用的重要性,特别强调与光合作用相关的蛋白质积累的变化。我们专注于:(a)叶绿体蛋白在病毒感染过程中差异积累;(b)关于叶绿体-病毒相互作用的重要性;(c)改变植物的能量代谢以及随后克服病毒感染的植物防御机制。
