Project description:Fusarium verticillioides is a detrimental fungus that can contaminate maize grains with mycotoxins that are harmful to human and animal health. Breeding and growing resistant genotypes is one alternative to reduce contamination and subsequent production of mycotoxins by this fungus. However, little is known about the resistant mechanism relevant to breeding in this pathosystem. Therefore, our aim was to identify genes and metabolites that may be related to Fusarium ear rot resistance using resistant and susceptible maize inbreds. Kernels of the resistant inbred showed significantly reduced disease severity, and reduced levels of total fumonisin and ergosterol content compared with the susceptible one. Gene expression data were obtained from microarray hybridizations using F. verticillioides inoculated and non inoculated maize kernels. Differentially expressed sequences were identified and classified into 36 functional categories. Most of the differentially expressed genes were assigned to the categories “protein, RNA, DNA, stress, transport, signaling and cell metabolism”. These genes encode for PR proteins, detoxification and primary metabolism enzymes. Fungal inoculation did not produce considerable changes in gene expression and metabolites in the resistant L4637 inbred, probably due to a preformed or constitutive resistance mechanism. Defense-related genes were induced or repressed in kernels of the susceptible inbred L4674, responding specifically to the pathogen infection. The qRT-PCR in infected silks showed that glucanase, lipid transfer, xylanase inhibitor, PR1 and 26S proteosome transcripts had higher expression ratios in the susceptible line compared to the resistant one in response to fungal infection. Through this study, a global view of differential genes expressed and metabolites concentration during resistance and susceptibility to F. verticillioides inoculation has been obtained, giving additional information about the mechanisms and pathways conferring resistance to this important disease in maize. Global view of differential genes expressed during resistance and susceptibility to F. verticillioides inoculation. Two maize inbred lines : one resistant (L4637) and one susceptible (L4674) to F. verticillioides infection. Two-condition experiment, Inoculated (I) vs. non-inoculated (NI) lines. Biological replicates: 3 . One replicate per array.

Project description:An gene-expression comparison of the wild type and strain delta-fst1 of Fusarium verticillioides grown on autoclaved maize kernels for six days was conducted. Comparison of gene-expression between the wild type and strain delta-fst1 of Fusarium verticillioides grown on autoclaved maize kernels for six days. For each strain, RNA was isolated from four biological replicates. Sequences was obtain by HiSeq Illumina sequencer.

Project description:Investigation of whole genome gene expression level changes in F. verticillioides FRC M-3125 when exposed to 50 ug/ml 2-benzoxazolinone (BOA). Cultures were harvested two hours after exposure. Assessed in reference to control cultures of M-3125 exposed to ethanol (1% final concentration) since BOA was dissolved in ethanol. A four chip study using total RNA recovered from two separate control cultures of F. verticillioides FRC M-3125 in PDB containing 1% ethanol and two separate experimental cultures of M-3125 grown in PDB plus the added treatment of 50 ug/ml ethanolic BOA. The cultures were incubated for two hours on a rotary shaker (200 rpm) at 27C in the dark and then harvested by vacuum filtration and frozen in liquid nitrogen. The chips were a F. verticillioides custom 14K array based on platform GPL14669.

Project description:Investigation of whole genome gene expression level changes over time of Fusarium verticillioides wild-type in liquid fumonisin inducing media (GYAM). Fusarium verticillioides produces a polyketide derived mycotoxin, fumonsin, over time in liquid media (Proctor et al, Co-expression of 15 contiguous genes delineates a fumonisin biosynthetic gene cluster in Gibberella moniliformis, Fungal Genetics and Biology, 38:237-249). A twelve chip study using total RNA recovered from twelve wild type cultures of Fusarium verticillioides. Each chip measures the expression level of 13,288 genes with thirteen 60-mer probe pairs per gene.
