Aspergillus flavus is an opportunistic pathogen of ascomycetes, which can causes diseases on several important agricultural crops, especially peanut and maize. This fungus has the potential to produce a toxic metabolite known as aflatoxin, with carcinogenic, teratogenic and mutagenic effects to humans. A. flavus infection and aflatoxin contamination occur not only during the growing season, but also in the process of harvesting, drying, storage and transportation, which has a great impact on the safety of agricultural products and human health. Therefore, it is of great significance to analyze the infection process and molecular mechanism of A. flavus on grain and oil crops, which is benefit for resistant varieties breeding, the early warning and source control of aflatoxin contamination. This review summarized the infective process and molecular mechanism of A. flavus in peanut and maize, focusing on infection cycle, colonization site, infection process, influencing factors and infection mechanism of A. flavus. The purpose is to provide theoretical support for the prevention and control of aflatoxin contamination in agricultural products.

Key words: Aspergillus flavus, aflatoxin, peanut, maize, infection process, infection mechanism
