Observation of new leaf spot pathogen highlights nutritional properties of Rosa roxburghii and indicates novel risks to crops.
Key Points
Pathogen identification confirmed using molecular characterization and phylogenetic tree analysis, establishing N. formicidarum as the causative agent.
Molecular characterization of isolates included analysis of the ITS region, β-tubulin, and translation elongation factor 1-alpha genes.
Observation of leaf lesions led to symptomatic testing, demonstrating the pathogen's capacity to induce disease in R. roxburghii.
Economic implications underscore the urgent need for targeted control strategies against a new pathogen threatening crop yields.
