    A Gel-Free Budget-Friendly Approach to GFP-Tagged Viruses Quantification in Plant Samples

    Rohith Grandhi, Mélodie B. Plourde, Aditi Balasubramani, Hugo Germain*

    Phyton-International Journal of Experimental Botany, Vol.94, No.5, pp. 1497-1504, 2025, DOI:10.32604/phyton.2025.063974 - 29 May 2025

    Abstract Viral diseases are an important threat to crop yield, as they are responsible for losses greater than US$30 billion annually. Thus, understanding the dynamics of virus propagation within plant cells is essential for devising effective control strategies. However, viruses are complex to propagate and quantify. Existing methodologies for viral quantification tend to be expensive and time-consuming. Here, we present a rapid cost-effective approach to quantify viral propagation using an engineered virus expressing a fluorescent reporter. Using a microplate reader, we measured viral protein levels and we validated our findings through comparison by western blot analysis More >

    BIOCELL, Vol.46, No.9, pp. 2123-2131, 2022, DOI:10.32604/biocell.2022.020229 - 18 May 2022

    Abstract The NAC (NAM, ATAF, and CUC) superfamily is one of the largest plant-specific families containing transcription factors. An increasing number of studies suggest that NAC1 is involved in plants response to different biotic and abiotic stimulis. Nicotiana benthamiana is a widely used system for evaluating plant-pathogen interactions. In order to study the biochemical function of NbNAC1, NbNAC1 protein and antibody are essential. Therefore, we focused on developing a prokaryotic expression system for producing the Nicotiana benthamiana NbNAC1 protein of in Escherichia coli and the preparation of its polyclonal antibody. Firstly, we constructed two different molecular weight prokaryotic expression More >
