Deciphering the basis of resistance and susceptibility to Aspergillus flavus infection and aflatoxin in peanut (Arachis hypogaea L.) using comparative proteomics

ABSTRACT: 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.

Transcriptome and proteome analysis of resistant peanut pre-harvest seeds in response to Aspergillus flavus

Project description:In this study, we used RNA-seq to obtain and compare transcriptomic profiles of a resistant genotype J11 in pre-harvest seeds, with A. flavus inoculation at the whole-genome level. The TMT method was also implemented to help further understand the molecular mechanism of peanut resistance to A. flavus invasion at proteome level. Meanwhile, we conducted a thorough research on a chitinase and a NBS-LRR gene, which were found in our data. This study is our first step towards a comprehensive genome-scale platform for developing Aspergillus resistant peanut cultivars through genetic engineering.

Effect of Streptomyces roseolus cell free supernatant on fungal development, transcriptome and aflatoxin B1 production of Aspergillus flavus

Project description:Frequently observed in tropical and sub-tropical regions, crops contamination by aflatoxin B1 (AFB1) produced by Aspergillus flavus, is emerging in Europe, due to climate change. Many alternative methods are currently developed to reduce the use of chemical inputs to prevent mycotoxin contamination, such as biocontrol agents (BCAs). Actinobacteria are known to produce many bioactive compounds and some of them are able to reduce in vitro AFB1 concentration. In this context, the present study aims to analyze the effect of a cell free supernatant (CFS) from Streptomyces roseolus liquid culture on A. flavus development, as well as on its transcriptome profile using microarray assay and its impact on AFB1 concentration. To study the impact of Streptomyces roseolus cell free supernatant on global transcriptome of Aspergillus flavus we have employed whole genome microarray expression profiling.

Differential gene expression in resistant and susceptible peanut cultivars during Aspergillus infection

Project description:To identify peanut Aspergillus-interactive and Aspergillus-resistance genes, we carried out a large scale peanut Expressed Sequence Tag (EST) project followed by a peanut microarray study. For expression profiling, resistant and susceptible peanut cultivars were infected with a mixture of Aspergillus flavus and parasiticus spores. Microarray analysis identified 65 and 1 genes in resistant (C20) and susceptible (TF) cultivars, respectively, that were up-regulated in response to Aspergillus infection. In addition we identified 40 putative Aspergillus-resistance genes that were constitutively up-expressed in the resistant cultivar in comparison to the susceptible cultivar. Some of these genes were homologous to peanut, corn, and soybean genes previously shown to confer resistance to fungal infection. These results provide a comprehensive genome-scale platform for future studies focused on developing Aspergillus-resistant peanut cultivars through conventional breeding, marker-assisted breeding, or biotechnological methods by gene manipulation. Four samples were analyzed with four hybs. Two samples were obtained from resistant (C20) and and susceptible (TF) cultivars. Two factors were varied in the experimental design: (i) peanut cultivars (resistant (GT-C20) and susceptible (TF)) and (ii) Aspergillus exposure. A combination of these factors produced four hybridizations as follows: (1) C20Y vs. TFY (GT-C20 infected vs. TF infected) (2) C20Y vs. C20N (GT-C20 infected vs. not infected) (3) TFY vs. TFN (TF infected vs. not infected) (4) C20N vs. TFN (GT-C20 not infected vs. TF not infected)

Transcriptional profiles uncover Aspergillus flavus induced resistance in mature maize kernels

Project description:Aflatoxin contamination caused by the opportunistic pathogen A. flavus is a major concern in maize production prior to harvest and during storage. Previous studies indicate that both constitutive and induced resistance are involved in maize kernel defense against A. flavus infection, little is known about molecular mechanisms of mature kernels in response to fungal infection. The purpose of this study is to determine gene expression differences in maize kernels between resistant and susceptible lines in response to A. flavus challenge. To avoid the environmental effects in the field inoculation, a laboratory based inoculation technique Kernel Screening Assay (KSA) was used to challenge kernels with A. flavus. After 72 hours incubation of inoculated and noninculated mature kernels, gene expression profiles of two Near Isogenic Lines (NIL) of Eyl25 (A. flavus resistant) and Eyl31 (A. flavus susceptible) were compared using oligonucleotide array.

Global regulation of cell development and aflatoxin biosynthesis in Aspergillus flavus by Afper1

Project description:Aspergillus flavus contaminates crops during preharvest and post-harvest periods and produce carcinogenic mycotoxin aflatoxins posing severe threat to food safety and human health. To identify potential targets to tackle aflatoxin contamination, we have characterized a novel Afper1, sharing sequence identity with the yeast protein per1, regulating cell development and secondary metabolism in A. flavus. Notably, proteomics analysis revealed that the enzymes involved in extracellular hydrolases, conidial development, ER homeostasis, and aflatoxin biosynthesis significantly varied. Unexpectedly, enzymes participated in scavenging ROS including catA, catB, cpeB, and sodM were significantly downregulated and the accumulated ROS and sensitivity to hydrogen peroxide were confirmed by experiments. Surprisingly, Afper1 deletion significantly unregulated heterochromatin protein (HepA) and downregulated GNAT family acetyltransferase involved in heterochromatin formation. Accompanying the accumulated ROS and chromatin remodelling, enzymes participating in aflatoxins, ustiloxin B, and gliotoxin were impaired. These results implied that Afper1 affected chromatin remodelling and disturbed ER homeostasis leading to the accumulation of ROS, and ultimately resulted in growth defect and impaired secondary metabolites biosynthesis.

Genes Differentially Expressed by Aspergillus flavus Strains After Loss of Aflatoxin Production by Serial Transfers

Project description:Aflatoxins are carcinogenic fungal secondary metabolites. Levels of aflatoxins in agricultural commodities are stringently regulated by many countries. A cluster of genes is responsible for aflatoxin biosynthesis by Aspergillus flavus and other closely related species. Expression of the clustered aflatoxin genes is governed by a complex network of regulatory mechanisms. To better understand the molecular events that are associated with aflatoxin production, transcription profiling by microarray analyses which compared three independent aflatoxigenic A. flavus strains to individual isogenic progenies that no longer produced aflatoxins after serial transfers was carried out. Twenty-two significantly differentially expressed features were identified. After physical mapping using the A. oryzae genome sequence as the reference, the number of unique genes was reduced to 16. Compared to the parental strains, changes in the aflatoxin gene expression levels in the progenies were not significant, which suggests that the inability to produce aflatoxins is not caused by decreased expression. The only gene showing higher expression levels in the progenies is homologous to glutathione S-transferease genes. Overexpression of this gene, named hcc, at six- to nine-fold in an aflatoxigenic A. flavus did not cause discernible changes in colony morphology or aflatoxin production. Loss of aflatoxin production after serial transfers may not result from a single event but caused by multiple factors.
