Unraveling viruses associated with yellowing disease of cucurbitaceous crops in Tamil Nadu (India) through metatranscriptome sequencing

First Report of Moroccan Watermelon Mosaic Virus (MWMV) infecting Cucurbita pepo in Slovenia

From June to August 2025, cucurbit plants showing mosaic, blistering, crinkling, yellowing, and leaf deformation were collected from 27 locations in Slovenia (Supplementary Figure 1, 2) during an official survey for viruses listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. Six composite samples (...

Genome Characterization of a Novel Bisegmented Positive-Sense RNA Virus Infecting the Bean Flower Thrips (Megalurothrips usitatus) Reveals an Active Antiviral RNAi Response

By combining next-generation sequencing (NGS), reverse transcription polymerase chain reaction (RT-PCR), and rapid amplification of cDNA ends (RACE) PCR, we sequenced from adult bean flower thrips (Megalurothrips usitatus) the near-complete genome of a previously undescribed virus (related to Anopheline-associated C vi...

Molecular characterization and evolutionary dynamics of a mixed begomovirus infection associated with chilli leaf curl disease in Odisha, India.

Occurrence of Yellowing Viruses (CABYV, CCYV, and MABYV) in Cucurbit Crops in Korea and Development of a Multiplex RT-PCR Assay for Simultaneous Detection

This study investigated the occurrence of yellowing viruses in Korean cucurbit crops and developed a multiplex reverse transcription-polymerase chain reaction (RT-PCR) assay for their simultaneous detection. Between 2020 and 2024, symptomatic leaf samples from melon, cucumber, and watermelon were analyzed nationwide. C...

Metatranscriptomic profiling uncovers a distinctive pepper virome in tropical Indonesia

RNA-Seq-based metatranscriptomics reveals a CMV-dominated but regionally structured pepper virome in West Java and provides a foundation for virus surveillance and disease management in Indonesia.

First Report of Lychnis mottle virus Infecting Wild Tea ( Camellia taliensis ) in Yunnan, China

Lychnis mottle virus (LycMoV; genus Stralarivirus, family Secoviridae; RNA1, KR011032; RNA2, KR011033) is a bipartite positive-sense RNA virus previously reported from Lychnis spp. and associated with mottle symptoms (Fuchs et al. 2022; Yoo et al. 2015). Camellia taliensis (“Dali Cha”), a wild tea species, is known to...
