Rapid population growth poses a major challenge to global food security. Promoting sustainable agricultural production is necessary to ensure the global food security. Horticultural plants are a high-valued part in agricultural production. Virus and viroid diseases have long been a key factor limiting the horticultural production. Cultivation and distribution of pathogen-free plants is currently the most efficient practice for managing virus and viroid diseases, and their spread in the landscape. Cryotherapy-based methods are recently developed novel biotechnologies for the efficient production of pathogen-free plants. This review outlines updated information on the development and advances in cryotherapy-based methods for efficiently eradicating viruses and viroids in horticultural plants. Mechanisms underlining cryotherapy-based methods for improved pathogen eradication are discussed, and suggestions for further studies are proposed.

Although global raspberries production has grown in the past decade, it remains threatened by plant viruses. This study surveyed raspberry viruses and associated arthropods in the Czech Republic between 2021 and 2022 across five regions. A total of 257 plant and 151 arthropod samples were tested using RT-(q)PCR for 12 viruses listed in the EPPO Certification scheme, plus raspberry leaf blotch virus (RLBV) and a novel virus, tentatively named raspberry-associated virus A (RaVA). Raspberry bushy dwarf virus (RBDV) was most prevalent (51.8%), followed by black raspberry necrosis virus (BRNV, 42.0%) and raspberry leaf mottle virus (RLMV, 28.4%). Four viruses—arabis mosaic virus, apple mosaic virus, strawberry latent ringspot virus, raspberry ringspot virus—were not detected. RBDV was also identified in Sambucus nigra, a new host, while mixed RLBV and RaVA infection was found in wild Rubus occidentalis. RLBV was experimentally transmitted to Nicotiana occidentalis 37B in the presence of Phyllocoptes gracilis. Seven of 39 arthropod species carried viruses, but only two—Amphorophora rubi idaei and Aphis idaei—are known vectors. PCR amplicons from 92 isolates were sequenced, revealing high variability in several viruses. These findings offer new insights but highlight the need for continued monitoring and research.

Abstract Venom has independently evolved across many lineages, yet relatively few have been studied in detail, particularly among insects. Of these, Neuroptera (lacewings, antlions and relatives) remain largely unexplored, despite being widespread with agriculturally important groups such as green lacewings. While adults are non-venomous, neuropteran larvae are ferocious predators that use pincer-like mouthparts to inject paralysing and liquefying venom to subdue and consume their prey. Here, we provide a comprehensive investigation of the venom system in Neuroptera by integrating a high-quality genome, long-read transcriptomes spanning all life stages, microCT-reconstruction of venom glands, tissue-specific expression analyses, venom proteomics, and functional assays of the common green lacewing Chrysoperla carnea. We provide a re-description of the neuropteran venom system, demonstrate the venom’s insecticidal and cytotoxic activity, and show the venom comprises diverse toxin gene families and is richer and more similar to the venom of antlions than previously proposed. We show that this toxin arsenal is the result of a multitude of evolutionary events that include co-option, recruitment following gene duplication, diversification of toxin-paralogs by gene duplication, and functional innovation of new paralogs through both small structural and large architectural changes. In addition, we find that alternative splicing of toxin genes is an important contributor to the biochemical arsenal, which is a mechanism rarely documented among venomous animals. Our results demonstrate how multiple genomic and evolutionary mechanisms together contribute to the emergence and evolution of a complex molecular trait, and provide new insights into the evolution of venom in insects.

Angrep av plantepatogene sopp og nematoder kan redusere avling og kvalitet av norskdyrket korn. Soppsjukdommer i korn kan til en viss grad bekjempes ved bruk av soppmidler (fungicider) men ingen kjemiske midler er godkjente mot nematoder i Norge. Vi har analysert innhold av glukosinolater og isotiocyanater i røtter og blader fra 12 ulike korsblomstra vekster. Noen av de korsblomstra vekstene produserte spesifikke kjemiske forbindelser (allyl-isotiocyanat) som i våre forsøk viste seg å kunne hemme vekst av plantepatogene sopp og nematoder som forekommer i korn. Vi observerte redusert overlevelse av sopp på kornrester i jord etter innblanding av oppkutta blader fra korsblomstra vekster i jorda (veksthusforsøk). Vi påviste derimot ikke noen effekt på overlevelse av nematoder (egg) i jord. Vi ønsker videre å studere overlevelse av sopp og nematoder i jord/halmrester i feltforsøk med utvalgte korsblomstra vekster som fangvekst/ettervekst i korn (i potensielle fremtidige prosjekt)
