Abstract: In China，the pathogen causing apple ring rot disease is Botryosphaeria dothidea. This pathogen penetrates apples through natural orifices and secretes cell degrading enzymes to degrade the apple tissue and promote further infection. Apples can inhibit pathogen infection via the enhancement of cell wall lignification，release of antibacterial compounds，and production of immune proteins. Through a detailed review of the apple ring rot damage and pathogen types，pathogenesis mechanisms，and the resistance mechanisms of apples，this research systematically introduces apple ring rot resistance mechanisms and provides an important theoretical basis for effectively controlling this disease.

Key words: apple, apple ring rot, pathogenesis mechanism, resistance mechanism
