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 ：
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 ：
Remarkable phenotypic plasticity of phytoplasma infections stems from the fast evolution and functional divergence of a versatile effector arsenal. We first catalogue more than 50 characterised effectors, highlighting their interference with SPL/GATA, TCP, MADS-box and ARF hubs, and the combined consequences for plant morphogenesis, hormone homoeostasis and vector colonisation. We then explain how drastic genome reduction coexists with extensive repeats and is balanced by PMU-mediated replication and recombination to maintain genetic flexibility. Comparisons at the population level indicate that most effectors are located on PMUs, which promote the evolution of effectors through recombination, replication and horizontal transfer. Purifying selection preserves essential virulence functions and eliminates mutations that compromise effector activity, while diversifying selection fine-tunes host specificity and may aid evasion of host immune responses. Finally, we argue that elucidating the mechanistic link between the dynamics of PMUs and effector evolution may provide deeper insights into the molecular mechanisms of host manipulation.

Abstract ：
Phalaenopsis orchids are highly valued ornamental plants but are susceptible to viral infections that significantly reduce their commercial value. Traditional detection methods for viruses infecting phalaenopsis are limited in efficiency and scope. In this study, we employed high-throughput sequencing to identify viruses present in 82 samples from three major phalaenopsis cultivars-'Ama' (Phalaenopsis amabilis), 'Haojili' (P. haojili), and 'Hongfuqitian' (P. hongfuqitian)-in Fujian Province, China. We identified six positive-sense single-stranded RNA (+ssRNA) viruses, including Odontoglossum ringspot virus (ORSV) and tobacco mosaic virus (TMV), which are well-known to infect orchids, as well as four viruses not previously reported in phalaenopsis globally: tomato mottle mosaic virus (ToMMV), pepper mild mottle virus (PMMoV), plum pox virus (PPV), and tobacco etch virus (TEV). ORSV exhibited the highest detection rate at 86.59%, followed by TMV at 34.15%. The detection rates of ToMMV, PMMoV, and PPV were 4.88, 3.66, and 2.44%, with TEV having the lowest detection rate at only 1.22%. Coinfection was prevalent, with 37.80% of samples infected by two or more viruses. We designed specific primers and developed a one-step multiplex reverse-transcription polymerase chain reaction detection method optimized for these six viruses, achieving high specificity and efficiency. This method was validated using additional diseased samples, confirming its practicality for rapid virus detection. Our findings enrich the understanding of the phalaenopsis virome and within-host virus diversity and provide a valuable tool for early diagnosis and management of viral diseases, contributing to improved quarantine measures and control strategies in phalaenopsis cultivation.

Abstract ：
The brown planthopper (Nilaparvata lugens Stål, BPH) is the most destructive pest of rice (Oryza sativa L.). Utilization of resistant rice cultivars harboring resistance gene/s is an effective strategy for integrated pest management. Due to the co-evolution of BPH and rice, a single resistance gene may fail due to the alteration of the BPH virulent population. It is urgent to explore and map novel BPH resistance genes in rice germplasm. Previously, an indica landrace from India, Paedai kalibungga (PK) showed high resistance to BPH. A novel BPH resistance locus, BPH39 was mapped on rice chromosome 6S, using next-generation sequencing based bulked segregant analysis (BSA-seq). BPH39 was validated using flanking markers within the locus. Furthermore, near-isogenic lines carrying BPH39 (NIL-BPH39) were developed in the ZS97 background. NIL-BPH39 had the physiological mechanism of antibiosis and preference to BPH. BPH39 was finally delimited into an interval of 84 Kb ranging from 1.07-1.15 Mb. Six candidate genes were found in this region. Two of them (LOC_Os06g02930 and LOC_Os06g03030) encode proteins with a similar short consensus repeat (SCR) domain, which had many variations leading to amino acid substitutions and showed a higher expression level in NIL-BPH39. Therefore, these two genes are considered to be reliable candidate genes for BPH39. Furthermore, transcriptome sequencing, DEGs analysis and gene qRT-PCR verification preliminary revealed that BPH39 may be involved in the JA signaling pathway, thus mediating the molecular mechanism of BPH resistance. This work will facilitate map-based cloning and marker-assisted selection of the locus in BPH resistant breeding. © 2024, The Authors. All rights reserved.

The brown planthopper (Nilaparvata lugens St & aring;l, BPH) is the most destructive pest of rice (Oryza sativa L.). Utilizing resistant rice cultivars that harbor resistance gene/s is an effective strategy for integrated pest management. Due to the co-evolution of BPH and rice, a single resistance gene may fail because of changes in the virulent BPH population. Thus, it is urgent to explore and map novel BPH resistance genes in rice germplasm. Previously, an indica landrace from India, Paedai kalibungga (PK), demonstrated high resistance to BPH in both in Wuhan and Fuzhou, China. To map BPH resistance genes from PK, a BC1F2:3 population derived from crosses of PK and a susceptible parent, Zhenshan 97 (ZS97), was developed and evaluated for BPH resistance. A novel BPH resistance locus, BPH39, was mapped on the short arm of rice chromosome 6 using next-generation sequencing-based bulked segregant analysis (BSA-seq). BPH39 was validated using flanking markers within the locus. Furthermore, near-isogenic lines carrying BPH39 (NIL-BPH39) were developed in the ZS97 background.

Additionally, transcriptome sequencing, DEGs analysis, and gene RT-qPCR verification preliminary revealed that BPH39 may be involved in the jasmonic acid (JA) signaling pathway, thus mediating the molecular mechanism of BPH resistance. This work will facilitate map-based cloning and marker-assisted selection for the locus in breeding programs targeting BPH resistance.

Abstract ：
Rice (Oryza sativa L.) production frequently faces threats from biotic and abiotic stressors, with rice ragged stunt virus (RRSV) as a substantial biotic factor. The relationship between inorganic phosphorus content and susceptibility to RRSV is crucial yet poorly understood. This study investigates how phosphorus metabolism influences rice resistance to RRSV, focusing on genetic manipulations that modulate this relationship. The RRSV infection increased phosphate (Pi) content in the aerial parts of rice plants by enhancing Pi uptake and transport. Furthermore, the upregulation of microRNA399d (miR399d) and the suppression of its target gene OsPHOSPHATE2 (OsPHO2) enhanced Pi accumulation, increasing rice susceptibility to RRSV infection. Additionally, elevated Pi levels, which are associated with altered reactive oxygen species (ROS) dynamics, reduced ROS activity and potentially dampened the plant's innate immune response to viral infection. The miR399d-PHOSPHATE2 module was identified as pivotal in mediating phosphate uptake and influencing susceptibility to RRSV through modulations in the phosphorus and ROS pathways. This study shed light on the regulatory mechanisms of phosphorus nutrition in rice, revealing a critical interaction between phosphorus metabolism, ROS dynamics, and viral defense. The findings suggest potential strategies for manipulating Pi levels to enhance plant resistance against viruses, opening avenues for agricultural improvements and disease management in rice. The microRNA399d-PHOSPHATE2 module regulates phosphate uptake, alters reactive oxygen species dynamics, and heightens rice susceptibility to the rice ragged stunt virus infections.

Abstract ：
This review provides a comprehensive overview of the current understanding of rice resistance to the brown planthopper (BPH), a major pest that poses significant threats to rice production through direct feeding damage and by transmitting viruses such as Rice grassy stunt virus (RGSV) and Rice ragged stunt virus (RRSV). We highlight the emergence of various BPH biotypes that have overcome specific resistance genes in rice. Advances in genetic mapping and cloning have identified 17 BPH resistance genes, classified into typical R genes encoding nucleotide-binding leucine-rich repeat (NLR) proteins and atypical R genes such as lectin receptor kinases and proteins affecting cell wall composition. The molecular mechanisms of these genes involve the activation of plant defense pathways mediated by phytohormones like jasmonic acid (JA), salicylic acid (SA), and ethylene, as well as the production of defensive metabolites. We also examine the complex interactions between BPH salivary proteins and rice defense responses, noting how salivary effectors can both suppress and trigger plant immunity. The development and improvement of BPH-resistant rice varieties through conventional breeding and molecular marker-assisted selection are discussed, including strategies like gene pyramiding to enhance resistance durability. Finally, we outline the challenges and future directions in breeding for durable BPH resistance, emphasizing the need for continued research on resistance mechanisms and the development of rice varieties with broad-spectrum and long-lasting resistance.
