By Ruben Rellan-Alvarez, , 0

Several studies on maize natural variation of metabolomics traits.

1.Genomic and metabolic prediction of complex heterotic traits in hybrid maize from Riedelsheimer et al., 2012

Data summary:

  • Study description: 285 Dent inbreds crossed with two testers. Samples taken from plants grown in the field for metabolite analysis. Using ~56K SNPs and data from 130 metabolites authors calculate general combining abilities for 7 biomass and bioenergy related traits.
  • Genotypic Data: MaizeSNP50, data not available.
  • Metabolite Data: 130 metabolites measured See supplementary material. Raw data not provided.
  • Sample Size: 285 Dent inbreds testcrossed with two testers giving a total of 570 testcrosses. In the trials of each of the three maturity groups, 100 genotypes, including five common check genotypes, were randomized in a 20 × 5 α-lattice design with two replications and were planted in 2-row plots.
  • Tissue: 5 cm cuts from fully developed third leaf collected 33 days after sowing.

2.Genome-wide association mapping of leaf metabolic profiles for dissecting complex traits in maize from Riedelsheimer et al., 2012

Data summary:

  • Study description: 285 Dent inbreds. Samples taken from plants grown in the field for metabolite analysis. Authors perform GWAS analysis with the metabolite abundance data.
  • Genotypic Data: MaizeSNP50, data not available.
  • Metabolite Data: 130 metabolites measured. Raw data not provided.
  • Sample Size: 285 Dent inbreds and five additional 4 additional European Flint lines. In the trials of each of the three maturity groups, 100 genotypes, including five common check genotypes, were randomized in a 20 × 5 α-lattice design with two replications and were planted in 2-row plots.
  • Tissue: 5 cm cuts from fully developed third leaf collected 33 days after sowing.

3.The maize leaf lipidome shows multilevel genetic control and high predictive value for agronomic traits from Riedelsheimer et al., 2013

Data summary:

  • Study description: 285 Dent inbreds. Samples taken from plants grown in the field for metabolite analysis. Authors perform GWAS analysis with the lipidome abundance data.
  • Genotypic Data: MaizeSNP50, data not available.
  • Metabolite Data: 563 lipids measured. Raw data not provided. Average mean intensity for each of the lipids can be found on the supplementary pdf
  • Sample Size: 285 Dent inbreds and five additional 4 additional European Flint lines. In the trials of each of the three maturity groups, 100 genotypes, including five common check genotypes, were randomized in a 20 × 5 α-lattice design with two replications and were planted in 2-row plots.
  • Tissue: 5 cm cuts from fully developed third leaf collected 33 days after sowing.
