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 ：
Introduction Metagenomic analyses has significantly advanced our understanding of viral evolution and their functions within organismal biology. In particular, exploring the virome of agricultural pests like the white-backed planthopper (WBPH) is essential for understanding their role as potential virus vectors and developing effective pest management strategies.Methods To explore viral diversity, we collected white-backed planthoppers (WBPHs) from nine sites spanning four Chinese provinces (Liaoning, Fujian, Guangxi, and Yunnan) and performed metagenomic sequencing.Results Our analysis identified 11 novel viruses belonging to 7 viral families, encompassing positive-sense single-stranded RNA (+ssRNA), negative-sense single-stranded RNA (-ssRNA), and double-stranded RNA (dsRNA) viruses. Remarkably, eight of the southern Chinese sites, excluding one in Liaoning province, contained a previously undiscovered Sobelivirales virus. Using rapid-amplification of cDNA ends (RACE), we determined the complete genome sequence of this novel Sobelivirales virus. Subsequent analyses of its encoded proteins, potential structural domains, and phylogenetic relationships suggested that it may belong to a new genus within the Sobelivirales. Small RNA sequencing confirmed viral replication in WBPH by revealing that virus-derived small interfering RNAs (vsiRNAs) were primarily 21 and 22 nucleotides long.Discussion Our results have important implications for understanding virus carriage in WBPHs, evaluating their role as virus vectors, and informing the development of improved pest management strategies. Furthermore, this study highlights the power of metagenomics in uncovering novel viruses and expanding our knowledge of viral diversity.

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 ：
The present disclosure locates a new brown planthopper resistance gene BPH33.2 on the short arm of rice chromosome 4 by extreme mixed pool analysis (BSA-seq), and genetically transforming the gene BPH33.2 to make the susceptible rice to be the brown planthopper resistant phenotype rice; at the same time, the knockout of the gene BPH33.2 was used to cause the loss of the brown planthopper resistant phenotype in insect resistant rice, thus confirming the function of BPH33.2. The present disclosure also provides molecular markers closely linked with the rice brown planthopper resistance gene BPH33.2. Through experimental detection of molecular markers linked or co-segregated with these resistance loci, the brown planthopper resistance of rice plants can be accurately predicted at the seedling stage, accelerating the progress of the selection of brown planthopper-resistant rice varieties.

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.
