Plant viruses participate as biotrophic parasites in complex interactions with their hosts, resulting in the regulation of a diverse range of chloroplast/mitochondria-related genes that are essential for mediating immune responses. In this study, integrative systems biology approaches were applied to identify chloroplast/mitochondrial genes during viral infections caused by a wide number of viruses in , tobacco (), and rice (). These findings indicated that 1.5% of the DEGs were common between /tobacco and /rice, whereas 0.1% of the DEGs were shared among all species. Approximately 90% of common DEGs are uniquely associated with chloroplasts and mitochondria in the host defense against viral infection and replication. The functions of WRKY, NAC, and MYB transcription factors in imparting resistance to viral infections can be established. Promoter analysis revealed that AP2/EREBP, DOF, and C2H2 zinc finger factors included the most frequent binding sites and played a more important role in plant-viral interactions. Comparative analysis revealed several miRNAs with defensive functions including miRNA156, miRNA160, and miRNA169. The PPI network revealed several key hub genes mostly related to chloroplasts/mitochondria, including , , , , .20, and with upregulation, also , , , , , and with downregulation. Moreover, novel hub genes with unknown functions, such as and have been identified. This study represents the first preliminary systems biology approach to elucidate the roles of chloroplast/mitochondria-related genes in , tobacco, and rice against viral challenges by introducing valuable candidate genes for enhanced genetic engineering programs to develop virus-resistant crop varieties.
植物病毒作为生物营养型寄生物,与宿主进行复杂的相互作用,从而调控一系列对介导免疫反应至关重要的叶绿体/线粒体相关基因。在本研究中,采用综合系统生物学方法,鉴定了烟草和水稻中多种病毒感染期间的叶绿体/线粒体基因。这些发现表明,烟草和水稻之间1.5%的差异表达基因是共同的,而所有物种中共有0.1%的差异表达基因。在宿主抵御病毒感染和复制的过程中,约90%的共同差异表达基因与叶绿体和线粒体独特相关。可以确定WRKY、NAC和MYB转录因子在赋予病毒感染抗性方面的功能。启动子分析表明,AP2/EREBP、DOF和C2H2锌指因子包含最频繁的结合位点,在植物-病毒相互作用中发挥更重要的作用。比较分析揭示了几种具有防御功能的miRNA,包括miRNA156、miRNA160和miRNA169。蛋白质-蛋白质相互作用网络揭示了几个主要与叶绿体/线粒体相关的关键枢纽基因,包括、、、、.20以及上调的,还有下调的、、、、和。此外,还鉴定出了功能未知的新型枢纽基因,如和。本研究代表了首次采用初步的系统生物学方法,通过引入有价值的候选基因来加强基因工程计划,以培育抗病毒作物品种,从而阐明叶绿体/线粒体相关基因在烟草和水稻抵御病毒挑战中的作用。
