Mixed virus infection has increasingly become a problem in the production of Solanaceae crops in recent years; therefore, a fast and accurate detection method is needed. In this study, a novel triplex immunostrip assay was developed for the simultaneous detection of tobacco mosaic virus (TMV), tobacco vein banding mosaic virus (TVBMV), and potato virus Y (PVY). The limits of detection of this novel immunostrip reached 200 ppb (ng/ml), 1 ppm (µg/ml), and 2 ppm for TMV, PVY, and TVBMV particles, respectively. Importantly, no cross-reactivity was observed among TMV, TVBMV, and PVY or to a nontarget virus. When the assay was applied to suspected virus-infected tobacco, tomato, and potato samples collected from fields in Southwest China, samples of single or mixed virus infection were successfully identified. In conclusion, the triplex immunostrip assay provides a fast and easy to use on-site detection method for field epidemiological studies of TMV, TVBMV, and PVY, and for managing diseases that are caused by them.

Background: Virus infection and herbivory can alter the expression of stress-responsive genes in plants. This study employed high-throughput transcriptomic and alternative splicing analysis to understand the separate and combined impacts on host gene expression in Arabidopsis thaliana by Myzus persicae (green peach aphid), and turnip mosaic virus (TuMV).
Results: By investigating changes in transcript abundance, the data shows that aphids feeding on virus infected plants intensify the number of differentially expressed stress responsive genes compared to challenge by individual stressors.

Plant viruses pose a significant threat to global agriculture and require efficient tools for their timely detection. We present AutoPVPrimer, an innovative pipeline that integrates artificial intelligence (AI) and machine learning to accelerate the development of plant virus primers. The pipeline uses Biopython to automatically retrieve different genomic sequences from the NCBI database to increase the robustness of the subsequent primer design.

Passion fruit (Passiflora edulis) is a commercially important crop known for its nutritional value, high antioxidant content, and use in beverages and desserts. Gulupa baciliform virus A (GBVA), tentatively named Badnavirus in the family Caulimoviridae, is a cryptic circular double-stranded DNA (dsDNA, ≈6,951 bps) virus recently reported in Colombia with asymptomatic infection of passion fruit (Sepúlveda et al. 2022).

Passion fruit woodiness disease (PWD), caused by cowpea aphid-borne mosaic virus (CABMV), severely damages leaves and fruits, compromising passion fruit production. The dynamics of this infection in Passiflora spp. are still poorly understood.

Turnip mosaic virus (TuMV) poses a major threat to crops like Chinese cabbage, causing significant economic losses. A viable and effective strategy to manage such diseases is by improvement of genetic-based viral resistance. To achieve this, it is important to have detailed and wide-ranging genetic resources, necessitating genetic exploration.
