Abstract ：
The begomoviral V2 protein is known to be multifunctional, including its interaction with and inhibition of CYP1, a papain-like cysteine protease (PLCP). However, the effect of this interaction on viral pathogenicity remains unclear. Cotton leaf curl Multan virus (CLCuMuV), a typical monopartite begomovirus associated with a betasatellite, is one of the main pathogens responsible for cotton leaf curl disease. This study verifies the interaction between CLCuMuV V2 and NbCP15, a PLCP homologue in Nicotiana benthamiana. The results show that V2 can be cleaved by NbCP15 in vitro, with the N-terminal cleavage site located between the second and third amino acids. Using an Agrobacterium-mediated inoculation method, we investigated the influence of cleavage sites on viral pathogenicity. The findings indicate that mutation of the third amino acid in V2 (V2D3A) reduced the pathogenicity of both heterologous PVX and CLCuMuV. Additionally, the NbCP15 gene mutation in N. benthamiana (nbcp15) also resulted in reduced CLCuMuV pathogenicity. These results suggest that CLCuMuV V2 may promote viral infection through its interaction with plant PLCPs.

Abstract ：
Tomato chlorosis virus (ToCV), first reported in Florida, USA, in 1998, has since emerged in multiple regions worldwide, posing a significant threat to global tomato production. However, its origin, migration patterns, and evolutionary history remain poorly understood. In this study, we used Bayesian phylogeographic analysis of coat protein gene sequences from 155 ToCV isolates to reconstruct its phylogeographic history. Our results show that ToCV evolves at a rate of 6.24 x 10-4 subs/site/year (95% credibility interval: 4.35 x 10-4-8.28 x 10-4), with the most recent common ancestor dating back to 1882. The maximum clade credibility (MCC) tree revealed three major clades, with Clade 1-whose most recent common ancestor dates to approximately 1975-comprising over 90% of the isolates. Although the exact origin of ToCV remains uncertain, we identified five distinct migration pathways: one from Europe to the Americas, one from Europe to South Asia, one from the Middle East to East Asia, one from East Asia to mainland China, and one from mainland China to Europe. These findings underscore the complex global spread of ToCV and suggest that multiple geographic areas have contributed to its ongoing evolution and dissemination.

Abstract ：
The genome of a monopartite begomovirus, or the DNA-A component of a bipartite begomovirus, typically encodes six proteins: two on the viral strand (AV1/V1 and AV2/V2) and four on the complementary strand (AC1/ C1, AC2/C2, AC3/C3, AC4/C4). Recent studies, however, have identified additional begomoviral proteins with various functions. This paper reports that euphorbia leaf curl virus (EuLCV), a monopartite begomovirus, encodes a seventh protein, C5. Promoter activity of the upstream fragment of the EuLCV C5 gene was shown using a GUS expression vector. EuLCV C5 also enhanced the pathogenicity and accumulation of potato virus X (PVX) in Nicotiana benthamiana. Localization studies revealed that EuLCV C5 localizes to the cytoplasm and nucleus, forming granular structures on the cell membrane. Additionally, C5 acts as a post-transcriptional gene silencing (PTGS) suppressor. A C5 deletion mutant of EuLCV (EuLCV-Delta C5) exhibited reduced pathogenicity and viral accumulation compared to wild-type EuLCV in N. benthamiana.

Abstract ：
Yellow leaf disease (YLD) poses a significant challenge to areca palm cultivation, yet its etiology remains uncertain. During our investigation of YLD-affected areca palm plants, transcriptome sequencing revealed an RNA contig exhibiting striking similarities to the RNA-dependent RNA polymerase (RdRp) of ormycoviruses. Subsequent gene cloning techniques yielded the full-length sequence of this RNA, potentially representing either the complete or partial genome of a hitherto unidentified ormycovirus, tentatively named areca palm yellow leaf-associated ormycovirus (APYLaOMV). RT-PCR detection found that APYLaOMV is present in over 30% of YLD-affected areca palm samples but is absent in healthy ones, suggesting a potential link between APYLaOMV and YLD. In summary, these data could be valuable in understanding the etiology of YLD in areca palms.

Abstract ：
Tobacco curly shoot virus (TbCSV), a begomovirus, causes significant economic losses in tobacco and tomato crops across East, Southeast, and South Asia. Despite its agricultural importance, the evolutionary dynamics and emergence process of TbCSV remain poorly understood. This study analyzed the phylodynamics of TbCSV by examining its nucleotide sequences of the coat protein (CP) gene collected between 2000 and 2022. Using various combinations of priors, Bayes factor comparisons identified heterochronous datasets (3 x 100 million chains) generated from a strict molecular clock and Bayesian skyline tree priors as the most robust. The mean substitution rate of the CP gene was estimated at 6.50 x 10-4 substitutions/site/year (95% credibility interval: 4.74 x 10-4-8.50 x 10-4). TbCSV was inferred to have diverged around 1920 CE (95% credibility interval: 1887-1952), with its most probable origin in South Asia. These findings provide valuable insights for the phylogeography and evolutionary dynamics of TbCSV, and contribute to a broader understanding of begomovirus epidemiology.

Abstract ：
Geminiviruses are a family of single-stranded DNA viruses that cause significant yield losses in crop production worldwide. Transcription start site (TSS) mapping is crucial in understanding the gene expression mechanisms of geminiviruses. However, this often requires costly and laborious experiments. Rice stripe virus (RSV) has a mechanism called cap-snatching, whereby it cleaves cellular mRNAs and uses the 5 & PRIME; cleavage product, a cappedRNA leader (CRL), as primers for transcription. Our previous work demonstrated that RSV snatches CRLs from geminiviral mRNAs in co-infected plants, providing a convenient and powerful approach to map the TSSs of geminiviruses. However, co-infections are not always feasible for all geminiviruses. In this study, we evaluated the use of in vitro cap-snatching of RSV for the same purpose, using tomato yellow leaf curl virus (TYLCV) as an example. We incubated RNA extracted from TYLCV-infected plants with purified RSV ribonucleoproteins in a reaction mixture that supports in vitro cap-snatching of RSV. The RSV mRNAs produced in the reaction were deep sequenced. The CRLs snatched by RSV allowed us to locate 28 TSSs in TYLCV. These results provide support for using RSV's in vitro cap-snatching to map geminiviral TSSs.

Abstract ：
近年来，广东番木瓜曲叶病毒(Papaya leaf curl Guangdong virus, PaLCuGDV)和一品红曲叶病毒(Euphorbia leaf curl virus, EuLCV)经常在百香果(Passiflora edulis)上被鉴定。本研究从福建地区表现典型双生病毒危害症状的百香果上扩增得到该2种病毒的全长序列，分别为2 732和2 745 bp；为明确PaLCuGDV和EuLCV的致病性，利用同源重组技术构建了2种病毒的侵染性克隆，通过农杆菌(Agrobacterium tumefaciens)介导法接种本氏烟(Nicotiana benthamiana)，结果发现，接种EuLCV的本氏烟表现出明显矮化且顶端叶片畸形卷曲症状，受病害危害明显重于接种PaLCuGDV，后者仅表现新叶稍微卷曲和叶片黄化；2种病毒混合侵染，受病害危害重于单独接种EuLCV或PaLCuGDV。Southern blot结果显示，PaLCuGDV和EuLCV单独及混合接种的烟草均有较高的病毒积累量。本研究首次构建了PaLCuGDV的侵染性克隆，并发现EuLCV和PaLCuGDV复合侵染会加重病害症状。本研究为解析PaLCuGDV和EuLCV的致病机制提供参考。
