|a Mulberry zonate leaf spot disease (MZLSD) is an important fungal disease of mulberry trees, which seriously affects the productivity and quality of mulberry leaves. MZLSD has been widely reported in sericultural production areas in Guangxi, China, in recent years. In this study, the causal agent of MZLSD was isolated from symptomatic samples and identified as Gonatophragmium mori (Acrospermaceae) based on morphological characterization and molecular analyses using nucleotide sequences of the internal transcribed spacer (ITS) and large subunit ribosomal DNA (LSU rDNA). Pathogenicity tests confirmed that G. mori is the pathogen responsible for MZLSD. Furthermore, we isolated antagonistic endophytic bacteria (AEB) from healthy mulberry leaves. Plate confrontation experiments showed that the lipopeptide crude extracts (LPCE) of three endophytic bacteria can inhibit the growth of G. mori, and the diameter of the antibacterial circle reaches more than 60 mm when their concentration of LPCE is 200 mg/ml. Light microscopy and scanning electron microscopy revealed that LPCE caused drastic changes in mycelial morphology. Fluorescence microscopy and transmission electron microscopy showed that the LPCE-induced apoptosis-like cell death in G. mori hyphae. Finally, based on morphological and molecular features, we identified the three isolates as Bacillus subtilis DS07, B. subtilis DS32, and B. velezensis Q6, respectively. To our knowledge, this is the first time to identify G. mori by combining characterization and molecular analyses, and we provide timely information about the use of biocontrol agents for suppression of G. mori
