“…Research in plant virology has recently expanded beyond the scope of viruses and the discovery of new antiviral pathways. It now covers many related fields, including the utilization of plant viruses as inducers of biotic stress to explore unknown fundamental biological questions, RNA silencing, autophagy, resistance genes, plant hormones, intracellular and extracellular signal transduction, and the application of fungal viruses to control crop fungal pathogens (Wu et al, 2017; Zhu et al, 2017; Yang et al, 2018c; Ismayil et al, 2020a; Wang et al, 2020a; Yang et al, 2020c; Zhang et al, 2020c; Wang et al, 2021d; Chen et al, 2023a; Zhang et al, 2023a, 2023d). In addition, our understanding of the detrimental effects of viruses has enabled the development of beneficial viruses into valuable tools for many research applications, such as plant virus‐based expression constructs and gene silencing/editing vectors (Yuan et al, 2011; Ma et al, 2020; Li et al, 2021a, 2021e), which benefits functional genomics research in the life sciences and crop improvement, disease resistance, and molecular farming.…”
