Special Issue Information

Dear Colleagues,

Plant diseases remain one of the most pressing threats to global food security and agricultural sustainability. With the increasing challenges posed by emerging pathogens, climate change, and reduced efficacy of traditional chemical controls, it is imperative to develop innovative strategies that integrate plant immunity with ecological approaches for disease management.

Plant immunity research has advanced our understanding of host–pathogen interactions at the molecular, cellular, and physiological levels, revealing complex defense mechanisms ranging from pathogen-triggered immunity to systemic acquired resistance. Meanwhile, ecological control emphasizes the utilization of biodiversity, beneficial microbes, natural products, and agro-ecological practices to reduce disease incidence while promoting environmental sustainability. The integration of these two perspectives offers a holistic pathway toward durable crop protection and resilient agroecosystems.

This Special Issue is dedicated to original research and review articles covering all aspects of plant immunity and ecological disease control, including but not limited to molecular mechanisms of plant defense, host–pathogen co-evolution, microbiome-mediated resistance, ecological interactions shaping plant health, and plant disease indentification and sustainable strategies for its protection. By bringing together insights from molecular biology, ecology, and applied agriculture, this issue aims to foster cross-disciplinary dialogue and contribute to the development of innovative and environmentally friendly solutions for plant disease management.

Bean common mosaic virus (BCMV; Potyvirus phaseovulgaris) is one of the primary viruses that severely impacts the yield and quality of common beans (Phaseolus vulgaris L.) and has a worldwide distribution. Utilizing small RNA sequencing and RT-PCR validation, this study identified widespread co-infection by multiple viruses in field-collected common bean samples, with BCMV being the dominant viral species. A novel isolate, designated DY9, was obtained from these field samples. Pathotype characterization confirmed DY9 as pathotype PG-III, while previous studies reported all other PG-III members as Bean common mosaic necrosis virus (BCMNV). Whole-genome sequencing and phylogenetic analysis revealed that DY9 was genetically closer to BCMV and diverged significantly from known PG-III isolates. Based on these findings, we constructed an infectious clone of DY9. To address the genetic instability of Potyvirus in the Escherichia coli (E. coli) expression system, we discovered that inserting Intron 2 (derived from the NiR gene of P. vulgaris, GenBank: U10419.1) at position 2431 of the HC-Pro gene and targeting Intron 1 (derived from the ST LS1 gene of Solanum tuberosum, GenBank: X04753.1) at position 4240 of the CI gene significantly improved the stability of the cloning vector. The clone was verified to systemically infect common bean plants and induce typical mosaic symptoms. Infectivity was validated through RT-PCR, RT-qPCR, Western blotting, and transmission electron microscopy. This study represents the first successful construction of an infectious clone for pathotype PG-III BCMV, providing a critical reverse genetics tool for dissecting viral pathogenesis and identifying resistance genes. These findings not only expand the genetic diversity of BCMV but also offer a methodological reference for constructing infectious clones of Potyvirus species. Full article
