Penicillium expansum is a necrotrophic plant pathogen with a wide range of fruit hosts. It causes blue mold rot during fruit storage, transport, and sale, resulting in huge economic losses to the fruit industry. Moreover, this pathogen is also the main producer of patulin, a toxic secondary metabolite that contaminates fruit and fruit‐derived products and impairs human health. Therefore, understanding molecular basis of the pathogenicity and patulin biosynthesis of the fungal pathogen has important scientific significance and also plays an important guiding role in the research and development of new control technologies. Here, we comprehensively summarize the recent research progress, particularly regarding the molecular aspects of pathogenicity, patulin biosynthesis, and the related regulatory mechanisms, as well as control technologies for blue mold rot in the fruit industry.
