Project description:Head smut of maize, which is caused by the Sporisorium reilianum f. sp. Zeae (Kühn), has been a serious disease in maize. In order to find head smut resistant candidate genes, microarrays were used to monitor the gene expression profiles between disease resistant near isogenic lines (NIL) L282 and L43, highly resistant inbred line Q319 and highly susceptible inbred line Huangzao4 after 0 to7 days post inoculation of S.reiliana by artificial inoculation method.

Maize leaves were selected at 0d, 1d, 2d, 4d, 7d post inoculation for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain different expression genes of different varieties at each inoculation stage in order to find head smut resistant candidate genes.

Project description:Southern corn rust (SCR) is one of destructive diseases in maize caused by Puccinia polysora Undrew. (P. polysara), widely occurring in warm-temperate and tropical regions globally. To identify candidate SCR resistance-related proteins and understand the molecular mechanism underlaying the maize and P. polysara interaction, comparative proteomic analysis of susceptible and resistance maize lines was performed. A total of 6,612 proteins were successfully identified using an iTRAQ-based proteomic approach. Fold changes and statistical analysis demonstrated that 687 proteins increased and 802 proteins decreased in the resistant line, while 571 increased and 464 decreased in the susceptible line. One remorin protein, namely ZmREM1.3 (B4G1B0), was significantly induced by SCR in the resistant genotype, while decreased in susceptible genotype after P. polysara infection. Plant-specific remorin proteins have been shown to play important roles during microbial infection and plant signaling processes. Transgenic analysis showed that overexpression of ZmREM1.3 in maize confers enhanced resistance to the biotrophic fungal pathogen SCR. Upon pathogen challenge, the ZmREM1.3-overexpressing plants accumulated higher levels of defense hormones, SA and JA. Moreover, stronger induction of defense gene expression was also observed in ZmREM1.3-overexpressing maize plants in response to SCR infection. Taken together, our results support that ZmREM1.3 plays a positive role in regulating the maize defense against SCR likely through SA/JA-mediated defense signaling pathways. This is the first attempt for large scale analysis of the molecular mechanisms underlaying the maize and P. polysara interaction at the proteomic level, and the first evidence for remorin protein family in resistant to fungal disease.

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:In this study, the resistant and susceptible monoclonal CIK cell lines were first established which would be the ponderable research models for the nosogenesis mechanism of the hemorrhagic disease. C1 (CIK cells), R2 (resistant cells) and S3 (susceptible cells) samples were carried out RNA-Seq, MeDIP-Seq and small RNA-Seq by the next-generation sequencing strategy, bioinformatics analysis as well as experimental verification. It was discovered that the aboriginality of CIK cells were gravitated to the susceptible trait. And the discrepancies between resistance and susceptibility against GCRV could primarily attribute to antioxidant activity, cell killing activity and cell proliferation regulation. Here we comprehensively present the profiling and characteristics of DNA methylation and microRNA in the resistant and susceptible CIK cells and proposed that high mCHH methylation distribution might be a characteristic modulator in C. idella. What’s more, a series of genes modulated by DNA methylation or microRNA were designated as potential biomarkers for the resistance breeding. This study laid the foundation and opened novel avenues for nosogenesis research on hemorragic disease of C. idella.

Project description:Aflatoxin contamination occurring after infection by Aspergillus flavus is a major concern in maize production both pre- and post-harvest. A recent gene expression study of imbibed kernels highlighted induced resistance and gene regulation in kernels. In the present study, stored mRNA was profiled using oligo-nucleotide array. This comparison of stored mRNAs would enhance our understanding of the difference between resistant and susceptible lines at the kernel storage phase. To minimize the effect of different genetic backgrounds on the differential genes between resistant and susceptible lines, two closely related inbred lines were used. Of the two lines, Eyl25 is aflatoxin-resistant (R), and Eyl31 is –susceptible (S). These were derived from a cross between two resistant lines, 1368 and GT-MASK:gk, in the IITA and USDA- ARS collaborative breeding project.
