Abstract ：
Rice viruses frequently cause major yield losses, threatening global food security. In this study, we employed a multi-omics approach (transcriptome, small RNA and metabolome) to investigate the common and distinct responses of rice to three dwarfing viruses, rice ragged stunt virus, rice grassy stunt virus and Southern rice black-streaked dwarf virus. All three pathogens elicited notable dwarfing and increased tillering in infected plants, which significantly impacted yield potential. We identified thousands of DEGs and metabolites, revealing significant accumulation of phenylpropanoid intermediates, such as ferulic acid (FA) and cinnamic acid (CA). Despite the downregulation of lignin biosynthesis genes, total lignin content rose markedly, which indicated a feedback regulation mechanism that reinforced cell walls. Hormone signalling pathways were also reprogrammed, with elevated jasmonic acid (JA) and suppressed ethylene and abscisic acid pathways, which potentially weakened certain defences. Exogenous application of FA and CA effectively promoted lignin deposition and exerted a degree of inhibition on brown planthopper feeding. These findings highlighted the phenylpropanoid pathway as a critical nexus that linked plant structural reinforcement and defence responses. Our study provided novel targets for breeding virus-resistant rice cultivars and offered a broader framework for understanding plant-pathogen-insect interactions.

Abstract ：
Leaf morphogenesis is essential for plant growth and development, yet the mechanisms by which plant viruses induce changes in leaf shape are not well understood. Rice ragged stunt virus (RRSV) infection induces distinct morphological abnormalities in rice leaves, including leaf tip curling and serrated margins, through unknown pathogenic mechanisms. This study reveals that key regulatory microRNAs (miR164, miR319 and miR156) and their target genes (CUC, TCP and SPL) exhibit entirely opposite expression patterns in healthy and RRSV-infected leaves, indicating a profound impact on the leaf morphogenesis network. Significantly, the core protein OsCUC1, which typically functions by forming dimers, shows abnormal expression in the peripheral zone of the shoot apical meristem under viral infection, leading to disruptions in leaf development. OsTCP1 was found to dynamically regulate OsCUC1 dimer formation by modifying its subcellular localization and interacting with OsSPL14 and OsSPL17, thereby influencing their regulatory functions. Genetic disruptions of OsCUC1, OsTCP1 and OsSPL14/OsSPL17 enhance the severity of RRSV infection, demonstrating their critical involvement in the viral pathogenic strategy. The research uncovers a novel mechanism by which RRSV manipulates the expression and interactions of key regulatory factors, disrupting the delicate balance of the leaf morphogenesis network. These findings expand our understanding of viral manipulation of host development and provide a foundation for innovative strategies to enhance crop resilience.

Abstract ：
Liquid-liquid phase separation (LLPS) regulates diverse biological functions by mediating the assembly of biomolecular condensates. However, it remains unclear how host LLPS is targeted by viruses during infection. Here we show that a plant bunyaviral protein, the disease-specific protein (SP) encoded by rice stripe virus (RSV), possesses phase separation potential through its N-terminal intrinsically disordered region 1 (IDR1). In vivo, however, SP does not form phase-separated biomolecular condensates independently but utilizes its phase separation properties to interfere with the phase separation of the SERRATE protein (SE), a key component of Dicing bodies essential for microRNA processing. By disrupting SE phase separation, SP inhibits D-body assembly and miRNA biogenesis. Our study demonstrates that a viral protein can modulate host microRNA processing by targeting LLPS, revealing a previously uncharacterized mechanism involved in viral infection strategies and miRNA biogenesis regulation in plants.

Abstract ：
Rice, a major global food staple, is threatened by viral infections that hinder its growth and yield. We have recently shown that the virulence protein P3 of rice grassy stunt virus promotes pathogenesis by inducing proteasome-controlled degradation of the rice RNA polymerase IV (RNA Pol IV) protein NRPD1a controlled by the P3-interacting E3 ubiquitin ligase P3IP1. However, the underlying mechanisms remain elusive. In this study, we show that P3 acts as a virus-encoded transcription activator-like effector to upregulate transcription of somatic embryogenesis receptor kinase 4 (SERK4) by directly binding to its promoter. SERK4 phosphorylates P3IP1 and enhances RNA Pol IVa (NRPD1a) degradation following P3IP1-controlled ubiquitination, leading to attenuated antiviral defense in rice. Thus, our study finds a critical viral virulence strategy by encoding a transcription factor-like protein that activates a host kinase to promote proteasome-controlled degradation of NRPD1a, thereby disarming RNA-directed DNA methylation (RdDM) antiviral defense.
