Identification and biological characterization of pathogen causing sooty blotch of <i>Ardisia crispa</i> (Thunb.) A.DC.

ABSTRACT: Sooty blotch, a primary leaf disease affecting Ardisia crispa (Thunb.) A.DC. (A. crispa, AC), significantly impacts both the yield and quality of this medicinal plant. However, the specific species of pathogenic fungi responsible for this disease and their mechanisms of pathogenesis remain unclear. To elucidate the etiology of sooty blotch, it is essential to investigate effective prevention and treatment methods, and provide a theoretical basis for the effective protection of AC. Initially, the alterations in internal organelles that result in sooty blotch were examined using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Additionally, differential genes were analyzed using differential display reverse transcriptase-PCR (DDRT-PCR) in both heal
