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

ABSTRACT: 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.

Transcriptomic analysis of Aspergillus flavus in response to the solvent Dimethyl Sulfoxide

Project description:Dimethyl sulfoxide (DSMO) is a simple molecule widely used because of its great solvating ability. Beyond its physico-chemical properties, it is also biologically active, including on fungal species. Aspergillus flavus is a saprophytic and famous pathogenic fungus able to produce Aflatoxin B1 (AFB1), a potent carcinogenic mycotoxin which may contaminate many food crops. The aim of this study was to characterize the effect of DMSO on A. flavus transcriptome profile using high-throughput RNA-sequencing assay.

Genotypic and Phenotypic Versatility of Aspergillus flavus during Maize Exploitation

Project description:Several are the inputs which are able to modulate mycotoxin synthesis. In particular, when a fungus receives an external stimulus reacts by activating, through a quite well-defined signal cascade, an evident switch in its lifestyle. This profound change is also due to the activation of global gene regulators and, in particular, of transcription factors able to switch on the mycotoxin gene clusters expression. Aflatoxins (AF) are harmful carcinogenic compounds produced mainly by Aspergillus flavus and A. parasiticus. AF are produced during the contamination of maize kernels into the field, even if their role in phyto-toxicity is not yet assessed. Nevertheless, AF biosynthesis is tightly regulated by host-derived signals. Recently, the nature of some of these signals have been elucidated. In particular, a role in susceptibility and resistance of maize to A. flavus contamination has been assigned to some plant oxylipins. These findings draw a scenario in which a complex interplay is under way between A. flavus and maize. For uncovering all the implications of this cross-talk we decide to follow a holistic approach. In particular, we designed experimental conditions aimed to mimic the different phases of A. flavus infection cycle on maize and then by performing a microarray analysis on the harvested mycelia. The microarray data set has been processed for performing the differential expression analysis of almost 14000 gene probes, the pathway analysis based on the gene ontology and inter pro annotations, the secondary metabolites cluster co-expression analysis and an identification of groups of co-expressed neighbor genes, possibly associated with production of secondary metabolites.

Trp Amino acid supplementation of Aspergillus flavus NRRL 3357 and Aspergillus parasiticus SRRC 143

Project description:Aflatoxins are toxic and carcinogenic secondary metabolites produced by the fungi Aspergillus flavus and A. parasiticus. In order to better understand the molecular mechanisms that regulate aflatoxin production, the biosynthesis of the toxin in A. flavus and A. parasticus grown in yeast extract sucrose media supplemented with 50 mM tryptophan (Trp) were examined. A. flavus grown in the presence of 50 mM tryptophan was found to have significantly reduced aflatoxin B1 and B2 biosynthesis, while A. parasiticus cultures had significantly increased B1 and G1 biosynthesis. Microarray analysis of RNA extracted from fungi grown under these conditions revealed seventy seven genes that are expressed significantly different between A. flavus and A. parasiticus, including the aflatoxin biosynthetic genes aflD (nor-1), aflE (norA), and aflO (omtB). It is clear that the regulatory mechanisms of aflatoxin biosynthesis in response to Trp in A. flavus and A. parasiticus are different. These candidate genes may serve as regulatory factors of aflatoxin biosynthesis. Keywords: Aflatoxin, Aspergillus, flavus, Amnio Acids, Tryptophan

Genomic profile of maize response to A. flavus infection identifies genes associated with biotic and abiotic resistance

Project description:The experiment consisted of a field design containing two maize inbred lines Va35 and Mp313E. Va35 has yellow kernels and is susceptible to kernel infection by Aspergillus flavus (A. flavus). Mp313E is a white dent maize inbred line and was released primarily as a source of resistance to kernel infection by A. flavus. The test ears were inoculated with Aspergillus flavus and collected two days after inoculation. Non-inoculated ears collected 16 days after pollination were also used as a control. The microarray experimental design was a randomized complete block design with three replications. One microarray slide was used for each field plot. Each slide contained the inoculated and non-inoculated sub-treatments. A second slide for one replication of each genotype contained a dye swap for the inoculation treatment and three subsamples (dots) within the slide represented each contig. Keywords: Direct comparison

Transcriptional changes in Aspergillus flavus-infected maize kernels

Project description:Maize kernels are susceptible to infection by the opportunistic pathogen Aspergillus flavus. Infection results in reduction of grain quality and contamination of kernels with the highly carcinogenic mycotoxin, aflatoxin. To understand host response to infection by the fungus, transcription of approximately 9,000 maize genes were monitored during the host-pathogen interaction with a custom-designed Affymetrix GeneChipÂ® DNA array. More than 1,000 maize genes were found differentially expressed at a fold change of 2 or greater. This included the up regulation of defense-related genes and signaling pathways. Transcriptional changes also were observed in primary metabolism genes. Starch biosynthetic genes were down regulated during infection, while genes encoding maize hydrolytic enzymes, presumably involved in the degradation of host reserves, were up regulated. These data indicate that infection of the maize kernel A. flavus induced metabolic changes in the kernel, including the production of a defense response, as well as a disruption in kernel development. Maize kernels were mock inoculated at the blister (R2) or dough (R4) stage or inoculated with A. flavus at the blister (R2), milk (R3), dough (R4), or dent (R5) stage, and harvested 4 days later. Each treatment consisted of three biological replications. For each biological replication, 8 kernels were ground and RNA was isolated and further processed.

Human corneal epithelial cells internalize Aspergillus flavus spores by actin mediated endocytosis

Project description:Mycotic leratitis is the corneal inflammation predominantly caused by Fusarium and Aspergillus species. Corneal epithelium is the earliest cell type encounter the invading pathogen. The innate immune responses of human corneal epithelial cells against Aspergillus flavus is not known. Here we studied the role of human corneal epithelial cells against Aspergillus flavus infection. The results showed that corneal epithelial cells internalized Aspergillus flavus conidia through actin mediated polymerization surrounding the conidia. Further the actin inhibitor cytochalasin D treatment reduced the formation actin ring around the conidia. The engulfed conidia acquired endosomal proteins as revealed by immunofluorescence analsyisis. Mass spectromtery of phagosomal proteins confirmed the recruitment of endosomal proteins and other proteins involved in phagocytosis. These results show the involvement of corneal epithelial cells in anti fungal defense.
