Much is known about the molecular interactions between positive-strand RNA viruses and dicotyledon plants. However, many important viral pathogens of the monocotyledon rice crop contain negative-strand or double-strand RNA genomes. Recent studies have shown that virus-derived small-interfering RNAs (siRNAs), host microRNAs and phytohormones regulate antiviral responses in rice plants and that rice-infecting RNA viruses encode a diverse repertoire of multifunctional proteins with counter-defensive activities. Moreover, the interactions between viral virulence proteins and host susceptibility factors also shape the virus-rice arms race. This review will focus on these recent advances and discuss strategies and challenges in the translation of discoveries made on molecular virus-rice interactions into practical virus control measures.
关于正链 RNA 病毒与双子叶植物之间的分子相互作用，人们已经了解很多。然而，单子叶作物水稻的许多重要病毒病原体含有负链或双链 RNA 基因组。最近的研究表明，源自病毒的小干扰 RNA（siRNA）、宿主 microRNA 和植物激素调节水稻中的抗病毒反应，并且侵染水稻的 RNA 病毒编码具有多种反防御活性的多功能蛋白。此外，病毒毒力蛋白与宿主易感性因子之间的相互作用也塑造了病毒与水稻之间的军备竞赛。本综述将重点关注这些最新进展，并讨论将分子病毒-水稻相互作用方面的发现转化为实际病毒控制措施所面临的策略和挑战。
