Project description:A proteomic and metabolomic approach was conducted to decipher the biochemical bases of silage maize N utilization and metabolism in relation to growth and productivity. Leaf samples were collected on plants cultivated in the field, where they were subjected to optimal and low N fertilization treatments. The proteomic and metabolomic responses to low N was thus analyzed in 29 hybrids (29 different dent inbred lines crossed with the same flint inbred line). Ecophysiological and agronomic traits were measured on plants cultivated in the same fields. Multivariate analyses allowed us to connect the data obtained at these different levels of integration and to analyse the genetic variation of susceptibility to low N.

Project description:We applied a custom 2k micro-array with 2232 oligonucleotide sequences (50-70 nt) to a factorial with 29 parental inbred lines (16 Dent,13 Flint) of European maize (Zea mays L.). The selection of oligonucleotides was based on 47k-array expression data from a 14x7 factorial with 98 hybrids (GSE17754). The main fraction of oligonucleotides (1639) represents genes that showed differential expression between the parental genotypes in the 14x7 factorial and consistent association with HP for GY in cross validation runs to estimate prediction accuracies for this trait. In addition the array contains partial overlapping fractions of genes that correlated with HP/GY (378), HP/GDMC (200), or MPH/GY (345) and 205 representatives of the 6 most overrepresented biological processes among genes correlated with HP/GY in the 14x7 factorial.

Project description:We applied a custom 2k micro-array with 2232 oligonucleotide sequences (50-70 nt) to a factorial with 29 parental inbred lines (14 Dent, 15 Flint, 26 hybrids selected for their heterosis levels so that the extreme values and also the average values were covered) of European maize (Zea mays L.). The selection of oligonucleotides was based on 47k-array expression data from a 14x7 factorial with 98 hybrids (GSE17754). The main fraction of oligonucleotides (1639) represents genes that showed differential expression between the parental genotypes in the 14x7 factorial and consistent association with HP for GY in cross validation runs to estimate prediction accuracies for this trait.

Project description:BACKGROUND: Climate change will lead in the future to an occurrence of heat waves with a higher frequency and duration than observed today, which has the potential to cause severe damage to seedlings of temperate maize genotypes. In this study, we aimed to (I) assess phenotypic variation for heat tolerance of temperate European Flint and Dent maize inbred lines, (II) investigate the transcriptomic response of temperate maize to linearly increasing heat levels and, (III) identify genes associated with heat tolerance in a set of genotypes with contrasting heat tolerance behaviour. RESULTS: Strong phenotypic differences with respect to heat tolerance were observed between the examined maize inbred lines on a multi-trait level. We identified 607 heat responsive genes as well as 39 heat tolerance genes. CONCLUSION: Our findings indicate that individual inbred lines developed different genetic mechanisms in response to heat stress. We applied a novel statistical approach enabling the integration of multiple genotypes and stress levels in the analysis of abiotic stress expression studies.

Project description:In the current study a microarray (46k, University of Arizona, USA) analysis of 21 European maize (Zea mays L.) parental inbred lines (14 dent and 7 flint) was applied. The aim was the identification of parental genes which expression levels are correlated to heterosis and/or hybrid performance for grain yield (GY) and grain dry matter content (GDMC) in the hybrid progeny (F1). Therefore gene expression profiles of differentially expressed genes of the parental inbred lines at the seedling stage were correlated with GY- and GDMC-field data of 98 flint x dent factorial crosses gained at six different locations in Germany. The identification of heterosis-correlated genes is an approach for the characterization and also for the prediction of this phenomenon. For the analyses total RNA of seven days old seedlings was extracted and aminoallyl-labeled RNA probes were synthesized. RNA labeling (Cy3, Cy5) and hybridizations were performed according to the protocol of the maize oligonucleotide array project (http://www.maizearray.org). The microarrays were scanned (AppliedPrecision ArrayWorx Scanner, Applied Precision Inc., USA) and data were evaluated using the Software GenePix Pro 4.0 (Molecular Devices, Sunnyvale, USA). An experimental interwoven loop design was developed aiming to yield in a preferably low average variance among the hybridizations, especially between intergroup (dent lines vs. flint lines) hybridizations. As a result 12288 (28.3%) of the genes showed differential expression between any combination of inbred lines. These differentially expressed genes were used for subsequent field data correlation analyses.

Project description:Eighteen genetically-diverse maize hybrids (Zea mays, dent lines crossed to a flint inbred-line) were cultivated in the field. Two conditions of cultivation were analyzed: normal sowing and early sowing. Upon early sowing plants grew under lower temperatures than upon normal sowing. Young leaves were harvested for proteomics quantitative analysis after a thermal time (equivalent number of days after emergence at 20°C) of 17 to 18. Three replicates per genotype/condition combination were analyzed. Each replicate was made up of the mix of leaf samples of five different plants.

Project description:We report de novo genome assemblies, transcriptomes, annotations, and methylomes for the 26 maize inbreds that serve as the founders for the maize nested association mapping population. The data indicate that the number of pan-genes in maize exceeds 103,000 and that the ancient tetraploid character of maize continues to degrade by fractionation to the present day. Excellent contiguity over repeat arrays and complete annotation of centromeres further revealed the locations and internal structures of major cytological landmarks. We show that combining structural variation with SNPs can improve the power of quantitative mapping studies. Finally, we document variation at the level of DNA methylation, and demonstrate that unmethylated regions are enriched for cis-regulatory elements that correlate with known QTLs and changes in gene expression.
