Description The colonization of maize (Zea mays L.) and peanut (Arachis hypogaea L.) by the fungal
pathogen Aspergillus flavus results in the contamination of kernels with carcinogenic
mycotoxins known as aflatoxins leading to economic losses and potential health threats to
humans. The regulation of aflatoxin biosynthesis in various Aspergillus spp. has been
extensively studied, and has been shown to be related to oxidative stress responses. Given
that environmental stresses such as drought and heat stress result in the accumulation of
reactive oxygen species (ROS) within host plant tissues, host-derived ROS may play an
important role in cross-kingdom communication between host plants and A. flavus. Recent
technological advances in plant breeding have provided the tools necessary to study and
apply knowledge derived from metabolomic, proteomic, and transcriptomic studies in the
context of productive breeding populations. Here, we review the current understanding of
the potential roles of environmental stress, ROS, and aflatoxin in the interaction between A.
flavus and its host plants, and the current status in molecular breeding and marker
discovery for resistance to A. flavus colonization and aflatoxin contamination in maize and
peanut. We will also propose future directions and a working model for continuing research
efforts linking environmental stress tolerance and aflatoxin contamination resistance in
maize and peanut.
