This collaborative work by over 180 researchers from 40+ countries addresses the challenges posed “phantom agents”—putative pathogenic agents named in literature without supporting data on their existence. Those remain regulatory lists, creating barriers trade and plant certification. Historically identified based solely symptoms, these lack isolates or sequence data, making reliable detection risk assessment impossible. After reviewing 120 such across 10 key genera, we recommend removal...
Abstract The present study described a combining thermotherapy with meristem culture for improved eradication of onion yellow dwarf virus (OYDV) and shallot latent (SLV) from co‐infected in vitro‐cultured shoots. In shoots infected OYDV SLV were thermo‐treated at constant temperature 36°C 0, 2 4 weeks, then meristems (0.5 mm) containing 1–2 leaf primordia excised cultured shoot regrowth. Meristem without produced much higher levels survival (100%) regrowth (55%) than those (62% 32% regrowth)...
Abstract Plant virus eradication is a prerequisite for the use of virus‐free propagules sustainable crop production. In contrast, preservation required all types applied and basic research viruses. Shoot tip cryopreservation can act as double‐edged strategy, facilitating either or in cryoderived plants. Here, we tested efficacies shoot shallot ( Allium cepa var. aggregatum ). vitro stock shoots infected with onion yellow dwarf (OYDV) latent were thermotreated 0, 2, 4 weeks at constant...
<title>Abstract</title> By optimizing size of shoot tips, preculture medium and exposure duration to PVS2, we established an efficient wide-spectrum droplet-vitrification cryopreservation tips raspberry (<italic>Rubus idaeus</italic> L.). This protocol yielded 80–100% 67–100% survival regrowth levels in cryopreserved across 30 genotypes. Genetic integrity was assessed cryo-derived regenerants after 3 months post-cryopreservation using inter simple sequence repeat (ISSR), single nucleotide...
A novel negative-sense single-stranded RNA virus showing genetic similarity to viruses of the genus Rubodvirus has been found in raspberry plants Czech Republic and tentatively named rubodvirus 1 (RaRV1). Phylogenetic analysis confirmed its clustering within group, albeit distantly related other members. screening 679 plant 168 arthropod samples from Norway revealed RaRV1 10 shrubs, one batch Aphis idaei, individual Orius minutus. Furthermore, a distinct isolate this was found, sharing 95%...
Raspberry plants, valued for their fruits, are vulnerable to a range of viruses that adversely affect yield and quality. Utilizing high-throughput sequencing (HTS), we identified novel virus, tentatively named raspberry enamovirus 1 (RaEV1), in three distinct plants. This study provides comprehensive characterization RaEV1, focusing on its genomic structure, phylogeny, possible transmission routes. Analysis nearly complete genomes from 14 RaEV1 isolates highlighted regions variance,...
Abstract The presence of viral diseases poses a significant challenge to the high-quality, efficient, and sustainable production apples. Virus eradication use virus-free plants is currently most crucial method for preventing diseases. Among viruses affecting apples, apple stem grooving virus (ASGV) chlorotic leaf spot (ACLSV) present particular challenges in efficient from This study investigated effects exogenous salicylic acid (SA) treatment on these ‘Yanfu 8’ after combining thermotherapy...

Abstract By optimizing size of shoot tips, preculture medium and exposure duration to PVS2, we established an efficient wide-spectrum droplet-vitrification cryopreservation for tips raspberry ( Rubus idaeus L.). This protocol yielded 80–100% 67–100% survival regrowth levels in cryopreserved across 23 genotypes. Genetic integrity was assessed cryo-derived regenerants after 3 months post-cryopreservation using inter simple sequence repeat (ISSR), single nucleotide polymorphism (SNPs),...
<title>Abstract</title> Raspberry (<italic>Rubus idaeus</italic> L.) is susceptible to aphid-borne viruses. We studied the incidence of four them – black raspberry necrosis virus (BRNV), leaf mottle (RLMV), vein chlorosis (RVCV), and Rubus yellow net (RYNV) in plants aphids around Norwegian crops for three years (2019, 2021–2022). Most samples were from symptomatic plants. Applying RT-PCR, 274 107 aphid analyzed. All viruses found, but BRNV dominated: it was detected 93% 178 with only more...
Aim of study: Thrips in raspberry crops are receiving attention Scandinavian production because the increasing sighting their presence flowers. Specific information on thrips species occurring and damage potential is scarce, making management challenging. Therefore, this study aimed to identify flowers cultivated raspberry, Rubus idaeus L., South Norway. Area Sogndal, Luster Frogn, Southern Norway Material methods: Adult were sampled from eight commercial orchards counties Vestland Viken...
The adoption of the European Green Deal will limit acaricide use in high value crops like raspberry, to be replaced by biological control and other alternative strategies. More basic knowledge on mites such is then necessary, species, density, their role as vectors plant diseases. This study had four aims, focusing raspberry leaves at northern altitude: (1) identify mite species; (2) population densities; (3) investigate intra-plant distribution; (4) co-occurrence phytophagous mites, leaf...

Raspberries (Rubus idaeus L.), occurring in the temperate zone of northern hemisphere and blackberries (R. fruticosus cultivated growing all over world, are plant species family Rosaceae. These susceptible to phytoplasma infections, which cause Rubus stunt disease. It spreads uncontrolled by vegetative propagation plants (Linck Reineke 2019a) phloem-sucking insect vectors, especially Macropsis fuscula (Hemiptera: Cicadellidae) (de Fluiter van der Meer, 1953; Linck 2019b). During a survey...
Apple stem grooving virus (ASGV) is one of the most widespread and asymptomatic main viruses, that restrict production apple in world. Establishment rapid, simple, effective early detection method important. In this study, we established optimized a one-step reverse transcription - recombinase polymerase amplification (RT-RPA) method, using target-specific primers ASGV coat protein gene sequence, M-MLV transcriptase. This could be completed within 30 min at 40 °C, followed by visual results...
