Dataset Summary

Title	Deciphering the basis of resistance and susceptibility to Aspergillus flavus infection and aflatoxin in peanut (Arachis hypogaea L.) using comparative proteomics
Description	Aflatoxin contamination caused by Aspergillus flavus in peanut is a serious constraint for food safety and human health. However, molecular mechanism/s underlying the defense response is poorly understood. A comparative proteomic analysis was carried out between two contrasting peanut genotypes, JL24 (WT-susceptible) and a near-isogenic transgenic event (OE-Def) in the same background expressing defensin gene (resistant) with different time points, To understand the proteome changes in OE-Def and WT control lines, a label-free quantitative proteomics analysis was performed at 0, 24, 40, 56 and 72 h after A. flavus inoculation using UPLC-ESI-MS/MS. Several resistance proteins in the secondary metabolic pathways related to phenylpropanoids, flavonoids, and fatty acid biosynthesis were strongly induced in the resistant genotype.
