dc.description.abstractPresent throughout all classes of life, antimicrobial peptides (AMPs) confer defense against bacteria, viruses, fungi, and insects. Identifying maize AMPs would provide breeders with a new defense resource. Here, the investigation of maize AMPs is reported. The distribution of AMPs within a panel of ten Mississippi maize inbred lines with varying resistance to Lepidoptera larvae feeding and Aspergillus infection is explored to characterize their observed resistances. Homology data-mining with two comprehensive AMP databases revealed 88 unique maize AMP protein sequences across 81 genes in the MaizeGDB B73 genome assembly. AMP-related polymorphic sites were identified using genomic primers. Analyses with qRT-PCR revealed 8 differentially expressed maize AMP genes. Computational 3D models of AMPs are limited, and models of these eight maize AMP genes were predicted. Two-dimensional electrophoresis gels were used to contrast protein profiles of inbreds with varying resistance to identify regions related to AMPs and other defense-related protein.
