Preparation and characterization of SPc nanoparticles and SPc/lncRNA809. A The preparation process of SPc nanoparticles. B SPc nanocarriers combine with lncRNA809 through co-incubation to form SPc/lncRNA809 complexes. C Schematic illustration of the application of SPc/lncRNA809. Spray the prepared SPc/lncRNA809 solution onto the leaves of M. micromalus, and SPc/lncRNA809 is permeated into the leaves, followed by the release of lncRNA809 to inhibit pathogen invasion. D SPc/lncRNA809 complexes significantly enhanced the resistance of M. micromalus to Alternaria fungi. Scale bar, 1Â cm
