Abstract

Peanut (Arachis hypogaea L.) cultivated in tropical dryland agroecosystems faces a serious threat from Aspergillus flavus infection, which produces carcinogenic aflatoxins. This study aimed to synthesize host genetic tolerance mechanisms, pathogen strain diversity, and their interaction affecting fungal colonization and seed quality under dryland stress. A narrative review approach was applied to seventeen primary articles and seven supporting studies selected from PubMed, ProQuest, and ScienceDirect by adopting selected reporting elements of PRISMA 2020, then synthesized through four thematic clusters. The synthesis revealed that peanut tolerance is hierarchical and complementary across three defense levels, namely physical defense based on testa architecture, biochemical defense based on flavonoid accumulation (44.29% of total metabolites) and phenolic acids, and enzymatic-molecular defense through expression of eighteen hub genes and the candidate gene AhAftr1. Strain diversity of A. flavus at the morphotype, population structure, and pangenome levels (59% accessory genes) was closely associated with virulence and aflatoxin production variation. A study under semi-arid conditions reported that drought stress increased aflatoxin B1 contamination by up to 54.95%, with the pod-filling stage as the critical period. An integrated layered control strategy combining multi-trait breeding, atoxigenic biocontrol, and agronomic management is proposed as a site-specific direction for the drylands of West Nusa Tenggara, particularly Lombok Island, and still requires field validation
