Project description:Methylation of chromosomal DNA in animals and plants is a fundamental mechanism of epigenetic regulation, and the maize genome, with its diverse complement of transposons and repeats, is a paradigm for transgenerational mechanisms such as paramutation and imprinting. We have determined the genome-wide cytosine methylation map of two maize inbred lines, B73 and Mo17, at high coverage and at single nucleotide resolution. Transposon methylation is highest in CG (65%) and CHG (50%) contexts (where H = A, C or T), while methylation in CHH (5%) contexts is guided by 24nt small interfering RNA (siRNA), and not by 21-22nt siRNA. We have found that CG (8%) methylation seems to deter insertion of Mutator transposons into exons, while CHH and CHG methylation at splice donor and acceptor sites strongly inhibits RNA splicing. Methylation differences between parents are inherited in recombinant inbred lines, but methylation switches, guided by siRNA, are widespread and persist for up to 8 generations. These differences influence splicing, and recurrent switching suggest that paramutation is much more common than previously supposed, and may contribute to heterosis. Our results provide a comprehensive high resolution resource for maize genome methylation, as well as a map of recurrent transgenerational epigenetic shifts (paramutation) in the two most commonly used inbred maize lines.

Project description:To acknowledge the molecular mechanisms underlying maize salt tolerance, two maize inbred lines, including salt-tolerant 8723 and salt-sensitive P138, were used in this study. Comparative proteomics of seedling roots from two maize inbred lines under 180 mM salt stress for 10 days was performed by the isobaric tags for relative and absolute quantitation (iTRAQ) approach. We obtained a total of 336237 spectra. 30616 peptides and a total of 7505 proteins were identified with 1% FDR. A total of 7505 differentially expressed proteins (DEPs) were identified. 626 DEPs were identified in line 8723 under salt stress, among them, 378 up-regulated and 248 down-regulated. 473 DEPs were identified in P138, of which 212 were up-regulated and 261 were down-regulated. Venn diagram analysis showed that 17 DEPs were up-regulated and 12 DEPs were down-regulated in the two inbred lines. In addition, 8 DEPs were up-regulated in line 8723 but down-regulated in P138, 6 DEPs were down-regulated in line 8723 but up-regulated in P138. In salt-stressed 8723, the DEPs were primarily associated with phenylpropanoid biosynthesis, starch and sucrose metabolism, and the MAPK signaling pathway. Intriguingly, the DEPs were only associated with the nitrogen metabolism pathway in P138. Compared to P138, the root response to salt stress in 8723 could maintain stronger water retention capacity, osmotic regulation ability, synergistic effects of antioxidant enzymes, energy supply capacity, signal transduction, ammonia detoxification ability, lipid metabolism, and nucleic acid synthesis. Based on the proteome sequencing information, changes in the abundance of 8 DEPs were correlated with the corresponding mRNA levels. Our results from this study may elucidate some details of salt tolerance mechanisms and salt tolerance breeding of maize.

Project description:Purpose: Breeding for gibberella ear rot resistance have been challenging due to the high complexity of the trait. The current study attempts to characterize defence responses to Fusarium graminearum infection in two maize inbred lines with different levels of resistance to the pathogen. Methods: RNA was extracted from developing kernels of two inbred lines, which had been either fungal (F. graminearum DAOM180378) or mock inoculated 11 days post sibcrossing, using a guanidine isothiocyanate method and ultra-centrifugation with cesium chloride. Isolated RNA was used to quantify whole genome gene expression using RNA-seq (Illumina TruSeq RNA library prep kit v2, Illumina HiSeq 2000). Paired end reads generated from RNA-seq were trimmed of adaptors and low quality reads, aligned with the B73 reference genome sequence version 2, expression levels (TPM) were computed and differential gene expression analysis were performed using CLC Genomics Workbench version 9. Results: Gene transcripts responding to fungal infection were captured by comparing gene expression levels in mock and fungal inoculated maize ears and gene ontology terms associated with significantly up-regulated gene transcripts were determined for each inbred. More genes were up regulated in the susceptible inbred relative to the resistant inbred, many of which are associated with oxidation-reduction processes potentially causing earlier programmed cell death in the susceptible inbred. Conclusions: This information helped to identify gene transcripts that were relevant in defense responses with potential applicability in routine breeding efforts and to propose an effective GER resistance mechanism.
